11.2 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.

NOTES:

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

2. If reverse direction is also required, ROTATION DIRECTION (Parameter 17) must be set to

FORWARD AND REVERSE (02), and TB-13A (Parameter 10) must be set to START REVERSE

(06). If reverse direction is not required, TB-12 must be wired directly to TB-2.

3. For 0-10 VDC or 4-20 mA speed control, use one of the following methods:

1. Program one of the TB-13 terminals (13A, 13B, or 13C) for 0-10 VDC (02) or 4-20 mA

(03). When that TB-13 terminal is closed to TB-2, the drive will respond to the selected speed

reference signal. If that TB-13 terminal is not closed to TB-2, the drive will respond to the

speed control source selected in Parameter 05 - STANDARD SPEED SOURCE. This

method must be used if it is necessary to toggle between two speed sources.

2. Program Parameter 05 - STANDARD SPEED SOURCE for 0-10 VDC (03) or 4-20 mA

(04). This method is preferable if only one speed source is required, as this method leaves the

TB-13 terminals free to be used for other functions.
