A resistor between this pin and pin 2 (Connector P2, Current Adjust) will proportionately reduced the current in both windings (1 second after the last positive going edge of the step clock input). The amount of current reduction will depend on the value of the resistor used. 2Current Adjust: Phase Current Adjustment input. A resistor connected between this input...

#L010068#L010068 1112 STEP MOTOR CONFIGURATIONS4 Lead Motors Step motors can be configured as 4, 6, or 8 leads. Each configuration requires different currents. Shown below are different lead configurations and the procedures to determine their output current. 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) use the specified per Phase (or unipolar) current rating to determine the current adjustment resistor value. This...

Phase 2&4 of the Step Motor is connected between pins 5 and 6 on connector P2. Refer to Figure 1 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 direction input, switch the wires on Phase 1 & Phase 3....
