August 2012 L01044011 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 the potentiometer setting table to choose the proper setting for the current setting potentiometer. Connecting the Step Motor The MBC25SI1TB is designed to accept one motor. For wiring of the motor refer to the pages containing the connector descriptions and hookups diagrams. 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! Circuit Protection This driver is equipped with over current protection. Note: When drive experiences a fault condition, it will seize to function. Power down, inspect wiring, motors, etc. and allow for a 30 second pause to resume functioning. If driver is too hot, additional ventilation and airfl ow should be added to prevent temperature to exceed recommended temperature limit.
August 2012 L01044012 Functions Hard Limit Switches: When a hard limit switch is encountered, the pulses will stop. Hard limits are intended as an emergency stop for your system. Soft Limit Switches: These switches cause the indexer to ramp down to the base speed and fi nish the index, unless encountering a hard limit switch. Profi le Inputs: These inputs are used to select and begin the specifi ed motion profi le. Only 1 input should be activated at a time. Motion Profi les: The indexer will accept two different speed or motion profi les. Each profi le has its own programmable Accel/Decel, Base speed and distance value. These values are stored in EEProm for standalone use and must be programmed before the pulse generator is ran. Acceleration/Deceleration: The acceleration and deceleration are by default the same value. This function controls the time that the motor will take to move from base speed to max speed. The higher the value, the slower the motor will accelerate. The same principle applies for the deceleration which is controlling the time it takes to go from maximum speed to base speed. The higher the value, the slower the pulses will decelerate. The different accel/decel profi les are stored in EEprom for standalone use. (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. The different base profi les are stored in EEprom for standalone use. (Range:1 to 5000) Max Speed: The max speed is the top speed the user wants the pulses to run at. This speed must always be equal or greater than the base speed. It is entered directly as the number of steps/ second. The different max profi les are stored in EEprom for standalone use. (Range:1 to 50,000) Index Number: The index number is the number of steps that the motor will take when the motion profi le starts. It is entered directly as the number of steps to take. The different index profi les are stored in EEprom for standalone use. (Range: 0 to 8,388,607) Direction Input: If this input is open then the unit will be running in the clockwise direction. If this input is active then the unit will be running in the counterclockwise direction. This pin can be overridden by the programmable software direction. It will activate the direction output when the pin is changed. This means, that if you start the profi le from the software, the unit will look at the software direction. If you start the indexer from the inputs, then the unit will look at the direction input. Busy Input: This output will be pulled low when the indexer is operating. It is an open drain output so when the indexer is not running the pin is open. Clock Output: The external clock is the output of the internal pulse that can be used to daisy chain other step motor drivers together. This is an open collector output that is capable of sink- ing 10mA.

August 2012 L01044016 Direct Talk Mode Direct mode is used to directly control the motion for real time movements through serial com- munication. The pulse generator has 14 commands which are easy to remember for direct movement of a step motor. COM Port Settings Baud Rate: 38400 Parity: None Data Bits: 8 Stop Bits: 1 Flow Control: Xon/Xoff Unit Selection In order to select a unit the @ command followed by 0 (address of the unit) must be sent. NOTE: There should be no spaces between the @ and the 0. How to select the unit: @0 (Unit is selected) How to get a response from the unit: @0$ (Carriage Return) After the $ command, the pulse generator will return a SMSI10 + the current version number Note: In direct talk mode each command is followed by a carriage return. The unit communicates in half duplex mode, therefore proper setup of hyper terminal is neces- sary to view characters, if characters are to be echoed back to the screen. Instructions All instructions require that no spaces be sent between the command and the parameter followed by a carriage return. The commands are also case sensitive and are all sent as capitals.
