7.2.3 Closed loop vector mode
Induction motor with incremental encoder feedback
For simplicity only an incremental quadrature encoder 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.
Action
Ensure:
Before
• Drive Enable signal is not given (terminal 31)
power-up
• Run signal is not given
• Motor and feedback device are connected
Ensure:
• Drive displays 'inh'
If the drive trips, see
Power-up
the 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:
• Drive encoder type in Pr 3.38 = Ab (0): Quadrature encoder
• Encoder power supply in Pr. 3.36 = 5V (0), 8V (1) or 15V (2)

Chapter 9 Diagnostics
Setting the encoder voltage supply too high for the
encoder could result in damage to the feedback device.
