NOTES

• Close TB-1 to TB-4 to RUN FORWARD and open TB-1 to TB-4 to STOP.

Close TB-13A to TB-4 to RUN REVERSE and open to STOP.

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

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

must be set to RUN REVERSE (06).

If reverse rotation is not required, simply close TB-1 to TB-4 to RUN,

and open to STOP (no other wiring or programming is required).

• 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, 13C or 13D 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. This method

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