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.

NOTES:

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

If REVERSE is not required, jumper TB-2 to TB-12A and eliminate the FWD/REV switch.

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 MANUAL speed control, which is determined by Parameter 29 - MANUAL.
