6.2.2 RFC-A mode (with position feedback)
Induction motor with position 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 Drive User Guide.
Action
Ensure:
Before
• Drive Enable signal is not given (terminal 11 and 13)
power-up
• Run signal is not given
• Motor and feedback device are connected
• Verify that RFC-A mode is displayed as the drive powers up. If the
mode is incorrect see section section 4.7

If output voltage from the encoder is >5 V, then the
termination resistors must be disabled Pr 03.039 to 0.
Setting the encoder voltage supply too high for the encoder
could result in damage to the feedback device.
0 = A-A\, B-B\, Z-Z\ termination resistors disabled
1 = A-A\, B-B\, termination resistors enabled, Z-Z\ termination
resistors disabled
2 = A-A\, B-B\, Z-Z\ termination resistors enabled
