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 .
