* With Heatsink

M2-D drives supply 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.

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

* Heatsink (part number 223-0159) is required if one side provides more than 5A or the total output of both
sides is more than 6.5A.
Line Fuse
If 115 VAC input line is used, wire an external line fuse in the hot leg between the stop switch
(if installed) and the L1 terminal. If 230 VAC input is used, fuse both legs.
Speed Potentiomenter Connections
Speed adjustments are supplied by speed potentiometers connected to J507 and J506
(Factory supplied pot kit includes two sets of potentiometer hardware. Part number: 202-0112).

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 J503)
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.
INHIBIT
Short inhibit terminals A(B) to bring motor A(B) to a stop. Inhibit A(B) is independant of inhibit B(A). The inhibit A
and inhibit B can be paralleled together.
J501
J501 is used by the factory to program the M2-D drive. Do NOT add any jumpers to J501.
TORQUE MODE (Jumper on pins 1 & 2 of J502 and pins 1 & 2 on J503)
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). The MIN SPEED A (B) and MAX SPEED A (B) are used to adjust the minimum and maximum torque
available.
C15
INDEPENDENT MODE (Jumper on pins 1 & 2 of J503)
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 for speed mode:
