7.2.4 Servo
Permanent magnet motor with a speed and position feedback device
For simplicity only an incremental quadrature encoder with commutation outputs will be
considered here. For information on setting up one of the other supported speed
feedback devices, refer to Setting up a feedback device in the Unidrive SP User Guide
on the CD Rom supplied with the drive

drive
Size 0 only: If no internal braking resistor is fitted then the drive will trip
'br.th'. If no internal braking resistor is required then set Pr 0.51 to 8 to
disable the trip.
Incremental encoder basic set-up
Enter:

with commutation outputs
• Encoder power supply in Pr. 3.36 = 5V (0), 8V (1) or 15V (2)

Setting the encoder voltage supply too high for the
encoder could result in damage to the feedback device.
