14.2.4 THREE-WIRE START/STOP CONTROL
A three-wire start/stop circuit can be accomplished by one of two methods on the MICRO Series drive.
Follow the appropriate procedure listed below:
FORWARD ROTATION ONLY
1.
Select REMOTE mode (see 14.2.1).
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 14.2.1).
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.
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.
