July 2002 2 DPV80001 Microstep Driver Pack Features Introduction The DPV80001 Microstep Motor Driver has an output current capability of 3.0 Amps minimum to 8.0 Amps maximum (Peak Rating). The inputs are optically isolated with a minimum sourcing of 1.0mA per input (+5VDC minimum to +24VDC maximum). The clock input is set to receive either positive or negative edge clocks with a maximum frequency of 100KHz. The DPV80001 driver offers direction control and motor current ON/OFF capabilities. The Reduce Current Enabled automatically reduces motor current to 70% of set value after the last step is made (20msec delay). The driver has built-in features to indicate power on (Green LED) and Clocks being received, greater than 100 Hz (Yellow LED). With the DPV80001, various step resolutions can be implemented by the onboard dip switch. These divisions range from 200 steps per revolution to 3200 steps per revolution. The bipolar drive configuration handles 4, 6, and 8 lead motors. Protection devices have been added to this driver for Phase to Phase Short-Circuit and Motor Miss-Wire conditions. Pin Descriptions The inputs on the DPV80001 are optically isolated with the anode (+) and cathode (-) both brought out to the user. With no current going through the opto-diode the input is considered high. To enable the input, a minimum of 1.0mA needs to be sourced or sinked through the opto-diode. This is done simply by placing a voltage of +5 to +24VDC across the two inputs of the opto-diode. If sourcing current in to the inputs, then all three cathodes (-) should be tied together and grounded as shown in the hookup drawing for sourcing. If sinking current, then all three anodes (+) should be tied together to the +voltage as shown in the hookup drawing for sinking. Provided on the DPV80001 is an external +5VDC out which can be used to power the inputs for sinking mode only. However if you use this voltage, isolation is not preserved. •Integrated MBC08161, 300W Power Supply, and Cooling Fan Universal Input, 90-265VAC Input Output Current 8.0 Amps Peak 200 to 3200 steps/rev (1,2,5,10 and 16 selectable step operations) Short Circuit Protection Motor Miss-Wire Detection No minimum Inductance Optical Isolation Motor ON/OFF Input TB2: 5 Pin Terminal Description Pin #Descrip tion 1Pha se A: Ph ase 1 of the step moto r 2Pha se A: Ph ase 3 of the step moto r 3Pha se B: Ph ase 2 of the step moto r 4Pha se B: Ph ase 4 of the step moto r 5Mo to r G r o u nd

July 2002 5 Optically Isolated Inputs The following inputs to the DPV80001 are Optically Isolated. To enable an input, apply a DC voltage source of +5VDC to +24VDC across the inputs. The Anodes (+) are pins 1,3,and 5 and the Cathodes (-) are pins 2, 4, and 6. Hook Up for Current Sourcing Inputs Motor Selection The DPV80001 is a Bipolar Microstep Driver that is compatible with both Bipolar and Unipolar Motor Configurations, (i.e. 8 and 4 lead motors, and 6 lead center tapped motors). Step motors with low current ratings and high inductance will perform better at low speeds, providing higher low-end torque. Motors with high current ratings and low inductance will perform better at higher speeds, providing more high-end torque. Since the DPV80001 is a constant current source, it is not necessary to use a motor that is rated at the same voltage as the supply voltage. What is important is that the DPV80001 is set to the appropriate current level based on the motor being used. Higher voltages will cause the current to flow faster through the motor coils. This in turn means higher step rates can be achieved. Anaheim Automation offers a comprehensive line of step motors in 17, 23, 34 and 42 frame sizes.

July 2002 7 Setting the Output Current The output current on the DPV80001 is set by an onboard potentiometer. This potentiometer determines the per phase peak output current of the driver. The relationship between the output current and the potentiometer value is as follows: Reducing Output Current Reducing the output current is accomplished by setting switch 1 of the DIP switch to the ON position and occurs approximately 1 second after the last positive going edge of the clock input. The amount of current per phase in the reduction mode is approximately 70% of the set current. When the current reduction circuit is activated, the current reduction resistor is paralleled with the current adjustment potentiometer. This lowers the total resistance value, and thus lowers the per Phase output current. Step Motor Configurations Step motors can be configured as 4, 6, or 8 leads. Each configuration requires different currents. Refer to the lead configurations and the procedures to determine their output current. WARNING! Step motors will run hot even when configured correctly. Damage may occur to the motor if a higher than specified current is used. Most specified motor currents are maximum values. Care should be taken to not exceed these ratings. Determining Output Current The output current for the motor used when microstepping is determined differently from that of a full/half step unipolar driver. In the DPV80001, a sine/cosine output function is used in rotating the motor. The output current for a given motor is determined by the motors current rating and the wiring configuration of the motor. There is a current adjustment potentiometer used to set the output current of the DPV80001. This sets the peak output current of the sine/cosine waves. The specified motor current (which is the unipolar value) is multiplied by a factor of 1.0, 1.4, or 2.0 depending on the motor configuration (series, half-coil, or parallel).

July 2002 8 4 Lead Motors Multiply the specified series motor current by 1.4 to determine the current adjustment potentiometer value. Four 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. 6 Lead Motors When configuring a 6 lead motor in a half-coil configuration (connected from one end of the coil to the center tap), multiply the specified per Phase (or unipolar) current rating by 1.4 to determine the current setting potentiometer value. This configuration will provide more torque at higher speeds when compared to the series configuration. When configuring the motor in a series configuration (connected from end to end with the center tap floating) use the specified per Phase (or unipolar) current rating to determine the current setting potenti- ometer value.
July 2002 9 8 Lead Motors Series Connection: When configuring the motor windings in series, use the per Phase (or unipolar) current rating to determine the current setting potentiometer value. Parallel Connection: When configuring 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 step motor selection guide 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 connector TB2. Phase 2 and 4 of the Step Motor is connected between pins 3 and 4 on connector TB2. The motors case can be grounded to pin 5 on connector TB2. 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 direction input, switch the wires on Phase 1 and Phase 3. WARNING: Do not connect or disconnect motor wires while power is applied! Miss-Wire Detection When power is applied to the DPV80001 there is a brief moment for miss-wire checks of the motor cables. If it is found that there is a miss-wire, the yellow LED will blink and power will be shut off to the motor. To reset the drive turn power off, check wiring, and turn power back on.
