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 is connected
Ensure:

deceleration set Pr 0.15 = FAST. Also ensure Pr 10.30 and Pr 10.31 are set
rates correctly, otherwise premature 'It.br' trips may be seen.)

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