15.3 THREE-WIRE START/STOP CONTROL
Shown below is the wiring diagram for a typical three-wire start/stop control scheme, using
momentary contacts (such as pushbuttons) for START and STOP commands. Also shown is
the wiring for a 0-10 VDC or 4-20 mA speed reference signal.
NOTES:
1. Momentarily close TB-12A to TB-2 to START, and momentarily open TB-1 to TB-2 to
STOP.
2. Program TB-13A, 13B, or 13C to select desired speed reference signal. Close the
selected TB-13 terminal to TB-2 to cause the drive to respond to the selected speed
reference signal. In the diagram above, TB-13A is the terminal programmed to select the
speed reference (either 0-10 VDC or 4-20 mA).
3. If the contact closure is not made between TB-13A and TB-2, the drive will default to
keypad speed control.
