11.4 THREE-WIRE START/STOP CONTROL

This wiring diagram shows a typical three-wire start/stop control scheme, using momentary

contacts (such as push-buttons) for START and STOP commands, and a selector switch to

select rotation direction.

NOTES

• Momentarily close TB-13A or TB-13D to TB-4 to START the drive in the

desired direction and momentarily open TB-1 to TB-4 to STOP the drive.

• For this conﬁguration, ROTATION DIRECTION (Parameter 17) must be

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

set to START REVERSE (07), and TB-13D (Parameter 49) must be set to

START FORWARD (05).

If reverse direction is not required, wire the START push-button

directly between TB-4 and TB-13D, and do not program TB-13A for

START REVERSE.

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

- Program Parameter 05 - STANDARD REFERENCE 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.

- Program one of the TB-13 terminals (13B or 13C are available in

this example) for 0-10 VDC (02) or 4-20 mA (03). When that TB-13

terminal is closed to TB-4, the drive will respond to the selected

speed reference signal. If that TB-13 terminal is not closed to TB-

4, the drive will respond to the speed control source selected in

Parameter 05 - STANDARD REFERENCE SOURCE.
