September 2012 L01019511 4 Lead Motors Multiply the specifi ed series motor current by 1.4 to determine the current adjustment potenti- ometer value. 4 lead motors are usually rated with their appropriate series current, as opposed to the Phase Current, which is the rating for 6 and 8 lead motors. 8 Lead Motors Series Connection: When confi guring the motor windings in series, use the per phase (or uni- polar) current rating to determine the current setting potentiometer value. Parallel Connection: When confi guring the motor windings in parallel, multiply the per phase (or unipolar) current rating by 2.0 to determine the current setting potentiometer value. Note: After the current has been determined, according to the motor connections above, use Table 3 to choose the proper setting for the current setting potentiometer. Connecting the Step Motor Phase 1 and 3 of the Step Motor is connected between pins 1 and 2 on the motor connector (TB2). Phase 2 and 4 of the Step Motor is connected between pins 3 and 4 on the motor con- nector (TB2). The motors case can be grounded to pin 5 on the motor connector (TB2). Refer to fi gures 2, 3, & 4 for TYPICAL APPLICATION HOOK-UP. Note: The physical direction of the motor with respect to the direction input will depend on the connection of the motor windings. To reverse the direction of the motor with respect to the direc- tion input, switch the wires on Phase 1 and Phase 3. WARNING! Do not connect or disconnect motor wires while power is applied! Short-Circuit, Mis-Wire, and Over-Current Conditions If it is found that there is a condition that causes an over current in the driver phase transistors, the Red LED will turn on solid and power will be shut off to the motor. To reset the drive turn power off, check wiring, and turn power back on.
September 2012 L01019512 Methods of Communication There are two methods for sending commands to the DPY50601. One is to directly talk to the DPY50601 by using Direct Talk Mode. This is usually used with a computer or PLC (Programmable Logic Controller), where the computer or PLC gives the DPY50601 serial commands to off-load its processor. For example: A PLC can utilize its outputs to toggle the DPY50601’s inputs and gain con- trol of variable speeds, variable programs, variable distances, etc. Simply using the DPY50601 as the intelligent pulse generator, a PLC can remove some of the tasks that were not meant for ladder logic or any PLC processing time. The second way to give commands to the DPY50601 is to use the software program SMC60WIN to either manually control, or to write and send programs. This method is used when the DPY50601 is the main controller. For example: A DPY50601 can replace simple motion control and replace I/O functional when minimal quantities of I/O are required to control specifi c machinery. Simple motion profi les that can operate with 6 or less inputs and 8 or less outputs can utilize a DPY50601 controller. Baud Rate A term used frequently is serial data communications, a “baud” is defi ned as the reciprocal of the shortest pulse duration in a data word signal, including start, stop, and parity bits. This is often taken to mean the same as “bits per second”, a term that expresses only the number of “data” bits per second. Very often, the parity bit is included as an information or data bit. The DPY50601 accepts a baud rate of 38400 only. RS232 Protocol - Controller SW1 in RS232 Position The DPY50601 is a DCE device, therefore it will transmit on pin 2 and receive on pin 3 of the DB9 RS-232 connector. The RS232 serial communication mode is single ended. This means that for each signal there is one wire, and a common ground reference used by all the signals. The DPY50601 does not use handshaking, thus the CTS and RTS lines are internally connected, and the CD, DTR and DSR lines are internally connected inside the DPY50601. The signal line maintains levels of +5VDC to +15VDC and -5VDC to -15VDC. For a valid logic level in the controller, the voltage must be at least +/- 3 volts. RS232 works at distances of up to 50 feet maximum. RS232 is susceptible to electrical noise, and should not be used in noisy areas. Always use the shortest cable con- nection possible. NOTE: Keep Controller wiring separated from motor cable/wiring. RS485 Protocol - Controller SW1 in RS485 Position The RS485 protocol mode is as follows; On board receivers will remain in active mode indefi nitely. Trans- mitters must be turned off when the unit is not sending data, to prevent the line from sending and receiving data at the same time. Therefore when the PC is transmitting data its driver will be turned on and each of the units connected will have their drivers off. If they are requested to send data back to the PC, the selected unit will turn it’s driver on to send the data and then turn it off after it has completed transmission. Note: The above protocol is done internally between the converter and the DPY50601. The RS485 method of communication allows increased noise immunity and increased communication distance of up to 4000 feet without repeaters. RS485 repeaters allow an additional 4000 feet per repeater. The DPY50601 is designed for two wire confi guration. The 2 wire confi guration makes use of the tristate capabilities of RS485 to allow a single pair of wires to share transmit and receive signals for half duplex communications. This “two wire” confi guration (note that an additional ground conductor must be used) reduces cabling cost. Note: Keep control wiring separated from motor cable/wiring. Section 3: Controller Functions
September 2012 L01019513 RS232 to RS485 for Multiple units or cables longer than 50ft The DPY50601 can be connected to your PC serial port via a RS485 converter (model number: 485SD9TB sold separately). This converter will convert the RS232 voltage signals to the com- patible RS485 differential signals. Only one converter box is needed per serial port. Contact the factory or use the website www.anaheimautomation.com for RS485 converter information and sales. Terminating Resistor To eliminate noise on the transmission lines or when using a 4000 ft. or longer cable, a terminat- ing resistor is suggested. If used, the termination resistor need only be added to the last (furthest from the converter box) DPD75601 in the network between pins A(-) and B(+) on the RS485 Terminal Block. The value of this resistor should be 120 ohms. Axis Selection Each DPY50601 is addressed using a programmable register allowing the PC to address up to 99 DPY50601’s from one port. The Default axis is “0”. To change the axis, use the SMC60WIN software or the “~” command. To verify or check the axis, use the SMC60WIN software or the “%” command. The axis designation is nonvolatile and will remain the same until changed by the user. Controller Status LED When powered and operated properly, the status LED will be green. When an error occurs, the LED will change to RED, and an error code will be generated in the error code register. To read and clear the error with software, click on the “Verify Parameters” button located in the “Motion Tab”. To read and clear the error while in “Direct Mode”, use the error code “!” command. Once the error has been read and cleared, the LED will return to green and the error code register will be cleared to 0. Refer to the table on page 39 for a complete list of the error codes. Technical Support Everyone needs assistance on occasion. If you have problems using any of the equipment cov- ered by this manual, please read the manual to see if it will answer your questions. Be sure to look in the Trouble-shooting Section located near the back of this manual. If you need assistance beyond what this manual can provide, you may call the factory direct for application assistance. If possible, have this manual in hand. It is often helpful to have the controller connected to a computer with the software installed.
September 2012 L01019514 Move Number of Steps: This command causes the motion to start in the direction last specifi ed. This command will move the motor the number of steps given. (Range: 1 to 8388607) Move to Position: The move to position command specifi es the next absolute position to go to. The DPY50601 controller automatically sets the direction and number of steps needed to go to that posi- tion. (Range: -8388607 to +8388607) Slew: The slew command will accelerate the motor up to maximum speed and continue to run at that speed until reaching a registration mark, hard limit switch, soft limit switch, receiving a “.” (stop hard) or “,” (stop soft) command. Set Position: The set position command sets the position register to a designated value. The number will be the new absolute position of the motor. The default value is 0. (Range: -8388607 to +8388607) Limit Switch Inputs: The limit switch inputs are internally pulled up by a resistor making them normally +5V. To activate the input, the pin must be grounded to (0VDC). All limit switch inputs are internally clamped to +5V, thus allowing voltages of up to +24VDC to be used. Hard Limit Inputs: When a hard limit switch is encountered, the motion will stop immediately. The position counter will also cease counting. Hard limits are intended as an emergency stop for your system. It should not be used to do any positioning type functions. These limits are directional. Soft limit Inputs: These switches should be used exclusively for homing. Once positioned properly with the appropriate parameters, it causes the motor to ramp down to the base speed before encoun- tering the home limit switch. However, the soft limit switch will work for any type of motion command. These limits are directional. NOTE: Whenever a soft limit switch is activated, the motor will decelerate and run at base speed during an indexing move, or stop during a slewing move. Be sure to come back past the soft limit switch to set any origins, otherwise the motor will decelerate as it goes past the soft limit switch dur- ing normal operation. Home Limit Input: This switch is used to establish a position designated “home” or datum position using the following: home to soft and home limit, or home to home limit. This limit is not directional. Home to Soft, Home Limit (2 Switch Operation): This type of homing routine requires two ground- ing type limit switched called home and soft. The fi rst limit switch seen is the soft limit. This will decelerate the motor down to base speed. The motor will then continue to run at base speed until it contacts the home limit switch input causing the motor to stop. The home limit switch activates as a hard limit if a soft limit is not sensed. The soft limit is directional, meaning that it will work in only one direction as specifi ed. The soft limit switch will work for any type of motion command. The home limit switch will work only for the two home motion commands. NOTE: There should be suffi cient distance between the two limit switches, as to let the motor reach base speed. Home to Home Limit (1 Switch Operation): This type of homing differs in that only one limit switch is needed. In this homing routine the motor moves toward the home limit switch. When the home limit switch is contacted the motor will ramp down to base speed, reverse direction and continue at base speed until the limit switch is released. This is a good way to compensate for any backlash in a system. It is also useful for minimizing the number of limit switches needed for homing. NOTE: The home switch needs to be low during the entire deceleration and reversing time.
September 2012 L01019515 Jog Inputs: The jog switch inputs are internally pulled up by a resistor making them normally +5 volts. To activate the input, the pin must be grounded to (0VDC). All jog switch inputs are internally clamped to +5V, thus allowing voltages of up to +24VDC to be used. Jog is a manual function. The user can select the direction and speed (fast or slow) by grounding the appropriate combinations of inputs. To jog a mo- tor, it is necessary to ground the jog input for the direction desired. For fast jog, both the fast input and jog input for the appropriate direction must be low at the same time. By grounding one of the jog inputs, the user causes the motor to run at base speed. When the fast input is grounded, the motor will then ac- celerate to the programmed jog speed. The position register will keep track of the number of steps that are taken during jogging. Once a +jog or a -jog function has been performed, the direction register will retain the last direction of movement; that is, a subsequent go command will be in the same direction as the last jog command. Inputs: All inputs (except input 1) are internally pulled up by a resistor making them normally +5V. To activate the input, the pin must be grounded to (0VDC). All inputs are internally clamped to +5V, thus al- lowing voltages of up to +24VDC to be used. Six inputs are provided per axis. The inputs are TTL, CMOS and 24V compatible. The inputs may be used to initiate a machine cycle, for inter-axis coordination (in stored program mode), for operator intervention, for sensing a machine condition such as out of stock or wait temperature to be reached, etc. A ground input will read a “0” and an open or high input will read as a “1”. Input 1 is a special input that is capable of reading an analog voltage between 0 and +5VDC. Since this input does not have a pull-up resistor, biasing of this input is needed if it is not used as an analog input. Inputs 5 and 6 are used together with the thumbwheel switch. To use inputs 5 and 6, SW2 of the controller must be in the IN5/6 position. If SW2 of the controller is in the TWS position, then these two inputs are not connected to the input port of the processor. Analog Input: Input 1 can be confi gured to read an analog voltage to either set the absolute position of the motor or to set the maximum speed of the motor. The set the position, when told via the go to analog position command, the input will read a voltage between 0 and +5VDC and based on the “upper and lower” limits of the function, a move will occur to a calculated position between the two limits. The motor must fi nish the move before it can be told to read the input again for the next position. For example, if the lower limit is set to 0 and the upper limit is set to 5000 and the analog position is set at +2.0VDC, then the motor will move to position 2000. Changing the lower limit to 1000 and the voltage to +3.2VDC, the motor will move to position 3560. See examples below for calculations of the analog inputs. (Range of limits: 0 to 65535 and the lower limit < upper limit) To set the max speed, when told via the set analog speed command the input will read a voltage between 0 and +5VDC, and based on the “upper and lower” limits of the function, a max speed can be obtained based on a calculated frequency between the two points. The speed however can not be changed when the DPY50601 is busy (moving). See examples below for calculations of the analog inputs. (Range of limits: 0 to 50000 and the lower limit < upper limit) Outputs: Eight outputs are provided per axis. Outputs may be used to operate relays, coolant valves, air cylinders, or, with the correct interfacing, any electronically controlled device. The outputs can drive all types of common peripheral power loads, including lamps, relays, solenoids, LED’s, printer heads, and heaters. For inductive loads, it will be necessary to connect a clamping diode (refer to specifi cation sec- tion) from the output to the power source in order to provide adequate fl y-back protection. The outputs are current sinking, open collector darlingtons. They are capable of sinking up to 100mA per output with voltages up to 40VDC. Turning an output on will pull the output pin to ground and turning an output off will make the output pin open. Output 1 has a special function (output on the fl y) that will enable it to be triggered at a certain absolute position during a move. Output 8 has a special function that will trigger when the encoder retries function fails. Analog Calculations Example 1: Example 2: (Upper-Lower) * (Voltage/5) = X (5000 - 0) * (2/5) = 2000 (5000 - 1000) * (3.2/5) = 2560 Lower + X = Position or Frequency 0 + 2000 = 2000 1000 + 2560 = 3560
September 2012 L01019516 Output on the fl y: This special function enables output 1 to turn on during a relative index or absolute move. There are three critical portions of information needed to make this function work correctly. First, output 1 will turn on (0VDC) for a preset delay of 50uS at a specifi c absolute position set by the 1 st output position command. Second, the output can then repeat this after a preset amount of steps set by the number of steps between outputs command, and third a predetermined amount of times to set the output is required by the number of outputs command which determines the preset amount of times to trigger the output. So if you start at position 0 and want to move to an absolute position of 10,000, you can set output 1 to turn on at position 2000, and every 1000 steps after that 5 times. So at position 2000, 3000, 4000, 5000, and 6000 output 1 will turn on for 50uS. To only have the output turn on at one position set both the “number of steps between outputs” and the “number of outputs” commands to 0. This function must be enabled, and will only work during a relative index or absolute position move. The output will trigger while going in either direction. If you do not want the output to trigger in the negative direction, the function must be turned off before the index move is started. Index on the fl y: This special function uses Input 2 when a motor is slewing to move a predetermined amount of steps, set with the registration index command, before stopping. This function must be enabled, and will only work during a slew move. The registration index must be set before movement begins. (Range: 1 to 8388607) End of Program: The end of program command, used within a stored program, stops execution of the program. This command must be used at the end of all programs. Wait: In stored program mode, the wait command pauses the program for the specifi ed number of mil- liseconds. (Range:1 to 65535) If/Then Statements: The if/then statements are conditional based on the values preset in the program. The user can either test each individual input or all inputs at once. If the input or input register matches the given value or values, then the program will execute the next line. If the input or input register does not match the given value, the program will skip the next line and execute the following line. An open input is read as a 1, and a grounded input is read as a 0. Branching or Goto statements: The go to instruction will have the program jump to the given label. If no label is in the program, it will error when trying to send. Return from Subroutine: This function can be placed anywhere in the program as long as a go to state- ment has already been executed. The program will jump back to the last go to statement encountered and executed the next line in the program. Inner and Outer Loop: The loop instructions allow the user to loop a program a variable number of times. The program will loop to the designated label location of the program. However, the label must always be at a lower line number than the loop instruction itself. You can only nest inner loops inside an outer loop. You may not nest an inner loop inside an inner loop, or an outer loop inside an outer loop. Multiple nested inner loops are allowed in one outer loop. Finish Move: When writing a program, the fi nish move command is used directly after every motion command. When using this command, the DPD75601 internally generates a busy signal and will wait until the move is complete before executing any further commands. Unless the fi nish move command is used, the DPD75601 will continue to execute the program. If it encounters a command that cannot be used when the motor is moving, the DPD75601 will error and stop the program prematurely. Repeat Last Move: This command will move the motor the number of steps given in the last indexing move. This command will not work correctly if the encoder auto correct function is enabled.
September 2012 L01019517 Encoder Commands: The DPY50601 controller is capable of using a quadrature incremental encoder with A and B channels. Encoder Auto Correct: This command will enable or disable the encoder feature of the DPY50601. When enabled, the encoder function will compare the desired position with the actual encoder position. If it is not in the correct position a correction move will be made. Encoder Delay: This sets the wait time, which is a specifi ed number of milliseconds after a relative index or absolute move is fi nished, prior to reading the encoder. This is used to remove the ringing that might be associated with the mechanics of the system. (Range: 0 to 65535) Encoder Motor Ratio: This represents the ratio for the number of encoder pulses to one motor step. This ratio must be a whole number. For example, given a 1000 line quadrature encoder and a 400 step/ revolution motor, the motor ratio is (1000 * 4)/400 = 10 (Range: 1 to 255 and must be a whole number). Encoder Retries: This is the number of times the DPY50601 will try to auto correct the motor shaft position before producing an error. When the error is produce, Output 8 is triggered. (Range: 0 to 255) Encoder Window: This is the allowable error in encoder pulses (either plus or minus) from the desired position that is allowed before the motor auto corrects. (Range: 0 to 255) Thumbwheel Index: This special function allows a thumbwheel with up to 7 decades to be used with the DPY50601 to set a relative index. To use the thumbwheel, SW2 must be in the TWS position or the thumbwheel will be disabled. Acceleration/Deceleration: The acceleration and deceleration are the same value. The acceleration is entered directly as steps/sec 2 and controls the time that the motor will take to move from base speed to max speed, and from max speed to base speed. The higher the value, the faster the motor will ac- celerate. The same principal applies for the deceleration which is controlling the time it takes to go from the max speed to base speed. (Range: 100 to 9,999,999) Base Speed: The base speed is the speed at which motion starts and stops. It is entered directly as the number of steps per second. This speed must always be less than the max speed and jog speed. (Range: 1 to 5000) Max Speed: The max speed is the top speed the user wants the motor to run. This speed must always be greater than the base speed. It is entered directly as the number of steps per second. (Range: 1 to 50000) Jog Speed: The jog speed sets the fast jog rate. Jog (+/-) is used to run at base speed. The FJOG pin when grounded, will ramp the motor to the set jog speed. This speed must always be greater than the base speed. It is entered directly as the number of steps per second. (Range: 1 to 50000) Motor Current: This command will control the ON/OFF output which is designed to connect to the ON/ OFF input of Anaheim Automation’s step motor drivers. To energize and allow current to fl ow through the coil of the motor, set the value to on. To de-energize and turn the current off to the motor, set the value to off. This is dedicated output and not controlled with the output register. Verify: The verify command causes the DPY50601 controller to send data back to the PC or PLC. The data is sent as an ASCII decimal string followed by a carriage return and a line feed. The verify com- mands are shown in the table on page 34.
