Action Detail
Before
power-up
Ensure:
• The drive enable signal is not given (terminal 31)
• Run signal is not given
• Motor is connected

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 max

Enter:
• Maximum frequency in Pr 00.002 (Hz)
Set accel. /
decel. rates
• Acceleration rate in Pr 00.003 (s /100 Hz)
• Deceleration rate in Pr 00.004 (s /100 Hz) (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
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).
Autotune
The drive is able to perform either a stationary or a rotating autotune. The
motor must be at a standstill before an auto-tune is enabled. A rotating
autotune should be used whenever possible so the measured value of
power factor of the motor is used by the drive
To perform an autotune:
•Set Pr 00.040 = 1 for a stationary autotune or set Pr 00.040 = 2 for a
rotating autotune
• Close the Drive Enable signal (terminal 31). The drive will display
’Ready’.
• Close the run signal (terminal 26 or 27). The lower display will flash
’Autotune’ while the drive is performing the autotune.
• Wait for the drive to display ’Ready’ or ‘Inhibit’ and for the motor to
come to a standstill.
• Remove the drive enable and run signal from the drive.
Save
parameters
Select 'Save Parameters' in Pr mm.000 (alternatively enter a value of
1000 in Pr mm.000) and press red reset button or toggle the reset
digital input.

base speed in the direction selected regardless of the
reference provided. Once complete the motor will coast to a
stop. The enable signal must be removed before the drive can
be made to run at the required reference.
