7.2.3 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 11 and 13)
• 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 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 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
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 auto-tune.
• 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)
Set
acceleration /
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).
Motor
thermistor
set-up
The motor thermistor connection is made through the drive encoder port
(terminal 15). The thermistor type is selected in P1 Thermistor Type
(03.118).
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
