NOTES:

• To use a -10 to +10 VDC speed reference signal, the following parameters

must be set:

P07 BIPOLAR REFERENCE SELECTION must be set to ENABLE (02).

P17 ROTATION must be set to FORWARD AND REVERSE (02).

P45 SPEED AT MIN SIGNAL must be set to the maximum desired

speed in the reverse direction.

P46 SPEED AT MAX SIGNAL must be set to the maximum desired

speed in the forward direction.

• In this conﬁguration, all other speed references are disabled except JOG

FORWARD and JOG REVERSE.

• In this conﬁguration, the RUN and START functions on TB-13A and

TB-13D will only start the drive, they will not select direction. Direction is

determined by the polarity of the -10 to +10 VDC signal.
