7.4.2 RFC mode
Induction motor
Run Drive is now ready to run
Action Detail
Action Detail
Before power-
up
Ensure:
• 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 Closed Loop mode is displayed as the drive powers up. If the mode is incorrect see Chapter
7.2 Changing the operating mode on page 115.
If a motor thermistor is not connected and the drive trips on ‘th’ set Pr 0.21 = VOLt and press the red
reset button.
Ensure:
• Drive displays ‘inh’
• Set the drive to closed loop vector mode. See Chapter 7.2 Changing the operating mode on page 115
for more information.
If the drive trips, see Chapter 13 Diagnostics on page 250.
Enter motor

details
Enter:
• Motor rated frequency in Pr 0.47 (Hz)
• Motor rated current in Pr 0.46 (A)
• Motor rated speed (base speed - slip speed) in Pr 0.45 (rpm)
• Motor rated voltage in Pr 0.44 (V) - check if or connection
Set maximum
speed
Enter:
• Maximum speed in Pr 0.02 (rpm)
Set acceleration
/ deceleration
rates
Enter:
• Acceleration rate in Pr 0.03 (s/1000rpm)
• Deceleration rate in Pr 0.04 (s/1000rpm) (If braking resistor installed, set Pr 0.15 = FAST. Also
ensure Pr 10.30 and Pr 10.31 are set correctly, otherwise premature ‘It.br’ trips may be seen.)
Select or
deselect catch a
spinning motor
mode
If catch a spinning motor mode is not required then set Pr 6.09 to 0.
If catch a spinning motor mode is required then leave Pr 6.09 at the default of 1, but depending on the
size of the motor the value in Pr 5.40 may need to be adjusted.
Pr 5.40 defines a scaling function used by the algorithm that detects the speed of the motor. The default
value of Pr 5.40 is 1 which is suitable for small motors (<4kW). For larger motors the value in Pr 5.40
will need to be increased. Approximate values of Pr 5.40 for different motor sizes are as follows, 2 for
11kW, 3 for 55kW and 5 for 150kW. If the value of Pr 5.40 is too large the motor may accelerate from
standstill when the drive is enabled. If the value of this parameter is too small the drive will detect the
motor speed as zero even if the motor is spinning.
