WARNING!

STOP ( TB-1) and EXTERNAL FAULT ( TB-13D) circuitry may be

disabled if parameters are reset to factory defaults! The drive must be

reprogrammed after a RESET in order to insure proper operation (see

Parameter 65 - PROGRAM).

FAILURE TO DO SO MAY RESULT IN DAMAGE TO EQUIPMENT

AND/OR INJURY TO PERSONNEL!

14.2.2 TWO-WIRE START/STOP CONTROL

A two-wire start/stop circuit can be accomplished by one of three methods on the
MC Series drive. Follow the appropriate procedure listed below:
FORWARD ROTATION ONLY

1. Select REMOTE mode (see above).
2. Connect a jumper between TB-12A and TB-2 to provide a permanent START

command to the drive.

3. Wire a normally open maintained contact between TB-1 and TB-2. Closing

this contact will RUN the drive and opening this contact will STOP the

drive.

FORWARD and REVERSE ROTATION

1. Select REMOTE mode (see above).
2. Program Parameter 27 - ROTATION to FWD & REV to allow rotation in both

directions.

3. Program Parameter 49 - TB13C to START REVERSE. This will force TB-

12A to act as START FORWARD.

4. Select the desired rotation by closing the appropriate terminal (TB-12A for

forward, or TB-13C for reverse) to TB-2. This can be done with a toggle

switch or equivalent circuit.

5. Wire a normally open maintained contact between TB-1 and TB-2. Close

this contact to RUN the drive, and open this contact to STOP the drive.

14.2.3 ALTERNATE TWO-WIRE START/STOP CONTROL METHOD

WARNING!

This method requires TB-13C to be set for RUN REVERSE, which will

disable TB-1 as a STOP switch! Incorrect use of TB-1 may result in

damage to equipment and/or injury to personnel! Refer to Parameter

49 - TB13C.

FORWARD ROTATION ONLY

1. Select REMOTE mode (see above).
2. Program Parameter 27 - ROTATION to FWD & REV.
3. Program Parameter 49 - TB13C to RUN REVERSE. This will force TB-12A

to act as RUN FORWARD.

4. Wire a normally open maintained contact between TB-12A and TB-2. Close

this contact to RUN the drive in FORWARD, and open this contact to STOP

the drive.
