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.
