FORWARD and REVERSE ROTATION with ONE RUN CONTACT
1. Follow 1-3 above and wire a normally open maintained contact between TB-
2 and the common of a single-pole, double-throw toggle switch. Wire the
poles of the toggle switch to TB-12A and TB-13C. Select the desired rotation
with the toggle switch. Close the maintained contact to RUN, and open to
STOP.
14.2.4 THREE-WIRE START/STOP CONTROL
A three-wire start/stop circuit can be accomplished by one of two methods on the
MC Series drive. Follow the appropriate procedure listed below:
FORWARD ROTATION ONLY
1. Select REMOTE mode (see above).
2. Wire a normally closed momentary STOP contact between TB-1 and TB-2.
Momentarily open this contact to STOP the drive.
3. Wire a normally open momentary START contact between TB-12A and TB-
2. Momentarily close this contact to START the drive.
FORWARD and REVERSE ROTATION with TWO START CONTACTS
1. Select REMOTE mode (see above).
2. Program Parameter 27 - ROTATION to FWD & REV.
3. Program Parameter 49 - TB13C to START REVERSE.
4. Wire a normally closed momentary STOP contact between TB-1 and TB-2.
Momentarily open this contact to STOP the drive.
5. Wire a normally open momentary START FORWARD contact between TB-
12A and TB-2. Momentarily close this contact to START the drive in
FORWARD.
6. Wire a normally open momentary START REVERSE contact between TB-
13C and TB-2. Momentarily close this contact to START the drive in
REVERSE.
NOTE: If the drive is operating in one direction, and is given the START command
for the opposite direction, the drive will decelerate to 0 Hz and then accelerate
back to the speed setpoint in the opposite direction.
