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 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 00.079 to RFC-A, then press the
stop/reset button to save the parameters.
Ensure: The drive displays: Inhibit (enable terminals are
open)
Enter minimum and
maximum speeds
Enter:
• Minimum speed Pr 00.001 (Hz)
• Maximum speed Pr 00.002 (Hz)
Enter accel and
decel rates
Enter:
• Acceleration rate Pr 00.003 (s/100 Hz)
• Deceleration rate Pr 00.004 (s/100 Hz)

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 00.038 = 1 for a stationary autotune or set
Pr 00.038 = 2 for a rotating autotune
• Close the drive enable signal (apply +24 V to terminal
31 & 34). The drive will display ’Ready’.
• Give a Run command (apply +24 V to terminal 12 -
Run forward or terminal 13 - Run reverse). The lower
display will flash ’Auto Tune’ while the drive is
performing the autotune.
• Wait for the drive to display ‘Inhibit’ 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
00.038
will be set
to 0.
Tuning of frequency
controller gains
(RFC-A mode only)
Depending on the application, the frequency controller gains
(Pr
00.065
and Pr
00.066
) may need to be adjusted.
Save parameters
Save parameters
