6.2.4 RFC-S mode (with position feedback)
Permanent magnet motor with a position feedback
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 Drive User Guide.
Action Detail
Before
power-up
Ensure:
• The drive enable signal is not given (terminal 31)
• Run signal is not given
• Motor and feedback device are connected
Power-up the
drive
Verify that RFC-S mode is displayed as the drive powers up. If the mode
is incorrect see section 4.7 Changing the operating mode on page 20
Ensure:
Drive displays ‘inhibit’

parameters
Incremental encoder basic set-up
Enter:
• Drive encoder type in Pr. 03.038 = AB Servo (3): Quadrature
encoder with commutation outputs
• Encoder power supply in Pr. 03.036 = 5 V (0), 8 V (1) or 15 V (2).
• Drive encoder Pulses Per Revolution 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
Motor
thermistor
set-up
At factory default, terminal 8 is set-up for an analog voltage input. If a
thermistor is connected to terminal 8, then the Analog Input 3 Mode
(07.015) parameter must be set to Thermistor Short Cct (7), Thermistor
(8) or Therm No Trip (9).
Enter motor
nameplate
details
Enter:
• Motor rated current in Pr 00.046 (A)
Ensure that this equal to or less than the Heavy Duty rating of the
drive otherwise ‘Motor Too Hot’ trips may occur during the autotune.
• Number of poles in Pr 00.042
• Motor rated voltage in Pr 00.044 (V)
Set
maximum
speed
Enter:
• Maximum speed in Pr 00.002 (rpm)
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
The thermistor input will be disabled until Pr 07.015 is set to
one of the above.
