15.2 TWOWIRE START/STOP CONTROL

Shown below is the wiring diagram for a typical two-wire start/stop control scheme, using

one maintained contact (such as that from a PLC) for RUN and STOP commands. Close

the contact to RUN, and open the contact to STOP. Also shown is the wiring for a 0-10

VDC or 4-20 mA speed reference signal.

The TB-2 terminals are internally tied together

NOTES:

1. Close TB-1 to TB-2 to RUN, and open to STOP.

2. If REVERSE direction is required, TB-13C must be set to START REVERSE

(refer to Parameter 49 - TB13C). If REVERSE is not required, simply jumper

TB-12A to TB-2.

3. Program TB-13A, 13B, or 13C to select the appropriate speed reference signal

that will control the drive speed (refer to Parameters 47, 48, and 49). When that

TB-13 terminal is closed to TB-2, the drive will respond to the selected speed

reference signal. In the diagram above, TB-13A is programmed to select either

a 0-10 VDC or 4-20 mA signal.

4. If the contact closure is not made between TB-13A and TB-2 to select a speed

reference, the drive will default to keypad speed control.
