Motor Connections

The 170-101-0212 drive supplies motor voltage from A+ and A- terimnals. It is assumed that

when A+ is positive with respect to A-, the motor will rotate clockwise (CW) while looking at the

output of the shaft protruding from the front of the motor. If this is opposite of the desired

rotation, reverse the wiring of the A+ and A- terminals.

Power Input

Connect the AC power leads to terminals L1 and L2, or to a double-pole single-throw master

power switch (recommended).

Line Fuse

Wire an external line fuse between the stop switch (if installed) and the L1 terminal.

Speed Potentiomenter Connections

Speed adjustments are supplied by speed potentiometers connected to J1 and J2 (Factory

supplied pot kit includes two sets of potentiometer hardware).

CALIBRATION / OPERATION

INDEPENDENT MODE (Jumper on pins 1 & 2 of J3)

There are two sets of potentiometers independently used to adjust each motor operation. Each set

consists of five on board trimmer potentiometers and one external potentiometer (commonly called

SPEED POT). To calibrate one side (A or B), use the following procedure:

1. Turn the SPEED POTENTIOMETER A (B) to full CCW. Use MIN SPEED A (B) trimmer

potentiometer to adjust minimum speed for motor A (B).

2. Turn the SPEED POTENTIOMETER A (B) to full CW. Use MAX SPEED A (B) trimmer

potentiometer to adjust maximum speed for motor A (B). Repeat steps 1 and 2 a few times due

to a level of interaction between MIN SPEED and MAX SPEED pots.

3. Set the CUR LIM A (B) to full CCW. Turn the SPEED POTENTIOMETER A (B) to full CW. Stall

the motor shaft and turn the CUR LIM A (B) CW until the desired current limit is reached.

4. Set the IR COMP A (B) to full CCW. Set the motor speed at approximately half of the rated

speed. Load motor to its full load. Keep turning the IR COMP CW until the speed equals the no

load speed.

5. Use ACC/DEC A (B) trimmer potentiometer to adjust acceleration (deceleration) ramp time.

RATIO MODE (Jumper on pins 2 & 3 of J3)

In RATIO MODE, SPEED POT A is used to adjust the speed of both motors, while SPEED POT B sets

the ratio between speeds. Turning the SPEED POT B CW will increase speed of motor B thus increasing

the ratio speed B/speed A. MIN SPEED B and MAX SPEED B are now used to adjust minimum and

maximum ratio.

TORQUE MODE (Jumper on pins 1 & 2 of J4)

TORQUE MODE regulates motor current (torque). In TORQUE MODE, the external potentiometer A (B)

sets the torque reference for Motor A (B) and the CUR LIM trimmer potentiometer A (B) sets the speed

limit for Motor A (B).

STOPPING: DECEL vs. COAST (J5)

There are two methods of stopping: DECEL and COAST.

DECEL - Placing a jumper on pins 1 and 2 of J5 and closing the inhibit terminals will cause the motor

to decelerate at a rate set by ACC/DEC pot.

COAST - Placing a jumper on pins 2 and 3 of J5 and closing the inhibit terminals will stop the

application of voltage to the motor, causing the motor to coast to a stop. This option is also

set for both motors simultaneously.

* NOTE: Deceleration time is a function of load inertia and friction. High inertia loads will decelerate

slower than high frictional loads.

Rotation: CW = Clockwise CCW = Counterclockwise
