7.2.2 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 Detail
Before
power-up
Ensure:
• Drive Enable signal is not given (terminal 11 and 13)
• Run signal is not given
• Motor and feedback device are connected
Power-up
the drive
• Verify that RFC-A mode is displayed as the drive powers up. If the
mode is incorrect see section section 5.6 Changing the operating
mode
on page 44.
Ensure:
• Drive displays ‘Inhibit’

parameters
Incremental encoder basic set-up
Enter:
• Drive encoder type in Pr 03.038 = AB (0): Quadrature encoder
• Encoder power supply in Pr. 03.036 = 5 V (0), 8 V (1) or 15 V (2).
• Drive encoder Lines Per Revolution (LPR) in Pr 03.034 (set
according to encoder)
• Drive encoder termination resistor setting in Pr 03.039:
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

details
Enter:
• Motor rated frequency in Pr 00.047 (Hz)
• Motor rated current in Pr 00.046 (A)
• Motor rated speed in Pr 00.045 (rpm)
• Motor rated voltage in Pr 00.044 (V) - check if or connection

Enter:
• Maximum speed in Pr 00.002 (rpm)

/
deceleration
rates
Enter:
• Acceleration rate in Pr 00.003 (s/1000 rpm)
• Deceleration rate in Pr 00.004 (s/1000 rpm) (If braking resistor
installed, set Pr 00.015 = FAST. Also ensure Pr 10.030, Pr 10.031
and Pr 10.061 are set correctly, otherwise premature ‘Brake R Too
Hot’ trips may be seen).
If output voltage from the encoder is >5 V, then the
termination resistors must be disabled Pr 03.039 to 0.
NOTE
Setting the encoder voltage supply too high for the encoder
could result in damage to the feedback device.
