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

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
