SECTION 2 QUICK START

STEP3 - Connect a Motor

Connect the step motor. Use Section 3, Motor Hook Up to assist. Set the Kick Current to match the

motors rated phase current. The kick current potentiometer is located on the driver side labeled Kick

Current Adjust. Whenever you are connecting wires to the Driver Pack, be certain that the power is

off or significant damage can occur.

STEP 4 - Connect the Switch and (Optional) LED

This switch is used as a “start switch” to cause the Driver Pack to begin sequencing through the program.

Connect one side of the switch to Pin #1 (Input #1) and the other side of the switch to Pin #5 (0 VDC).

The LED is optional. The LED demonstrates how an Output can be turned on and off. Connect the

Anode side of the LED to Pin # 11 (+5 VDC) and the Cathode side of the LED to Pin #13. Note: A

resistor must be placed in series with the LED to limit the current. A +5V LED has the series resistor

internally connected.

STEP 5 - Connect the Serial Cable to the Driver Pack

To connect your computer to the Driver Pack you need to connect the serial ports (usually COM1 or

COM2) to the units lower DB9 connector. This connector is labeled RS232/RS422 IN (P1). It is helpful

to know which communications port (Com Port) is in use when we setup the software. In most

computers, a 9 pin Male to Female cable will work.
