Most specified motor currents are maximum values. Care should be taken to not exceed these ratings. 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 potentiometer value. 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. User’s Guide # L010167 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 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 connector (TB2). The motors case can be grounded to pin 5 on the motor connector (TB2). Refer to the figures for the hook-up drawings for TYPICAL APPLICATION HOOK-UPS. 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! Short-Circuit, Mis-Wire, and Over-Current Conditions If it is found that there is a condition that causes on 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 0wiring, and turn power back on. Over-Temperature and Over-Voltage Conditions If it is found that there is an over temperature on the internal heat sink, or an over voltage on the motor bus voltage, the Red 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.
