Nidec Unidrive HS72 - RFC-A Mode (with Position Feedback)

38 Unidrive M702 / HS72 Control Getting Started Guide
Issue Number: 4
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 Control 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 4.7 Changing the operating mode on
page 21.
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
Enter motor
nameplate
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
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).
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.
