This section takes a new user through all the essential steps to running a motor for the first time.
Table 7-1 Open Loop and RFC-A
Action Detail
Before power up
Ensure:
• The drive enable signal is not given, terminal 31 and 34 is
open
• The run signal is not given, terminal 12/13 is open
• The motor is connected to the drive
• The motor connection is correct for the drive Δ or Y
• The correct supply voltage is connected to the drive
Power up the drive
The default setting is Open Loop vector mode. For RFC-A
mode set Pr 79 to RFC-A, then press the stop/reset
button to save the parameters.
Ensure: The drive displays: inh (enable terminal(s) is open)
Enter minimum and
maximum speeds
Enter:
• Minimum speed Pr 01 (Hz)
• Maximum speed Pr 02 (Hz)
Enter accel and
decel rates

Ready to autotune
Autotune
The drive is able to perform either a stationary or a rotating
autotune. The motor must be at a standstill before an autotune
is enabled.
To perform an autotune:
•Set Pr 38 = 1 for a stationary autotune or set Pr 38 = 2 for
a rotating autotune
• Close the drive enable signal (apply +24 V to terminal 31
& 34). The drive will display ’rdy’.
• Give a Run command (apply +24 V to terminal 12 - Run
forward or terminal 13 - Run reverse). The display will
flash ‘tuning’ while the drive is performing the autotune
• Wait for the drive to display ‘inh’ and for the motor to
come to a standstill.
• Remove the drive enable and run signal from the drive.
Autotune complete
When the autotune has been completed,
Pr
38
will be set to 0
Tuning of frequency
controller gains
(RFC-A mode only)
Depending on the application, the frequency controller gains
(Pr
65
and Pr
66
) may need to be adjusted.

Save parameters
Select ‘SAVE’ in Pr 00 or Pr mm.000 (alternatively enter a
value of 1001) and press the Stop / Reset button to save
