FORWARD and REVERSE ROTATION with TWO RUN CONTACTS

1. Follow 1-4 above and also wire a normally open maintained contact between

TB-13C and TB-2. Close this contact to RUN the drive in REVERSE, and

open this contact to STOP the drive.

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 set point in the opposite direction.

FORWARD and REVERSE ROTATION with ONE START CONTACT

1. Follow 1-4 above and wire a normally open momentary 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. Refer to the wiring

diagram in Section 15.3.
