Operating the Drive
4-5
650G AC Drive
Stationary or Rotating Autotune?
Will the motor spin freely, i.e. not connected to a load, during the Autotune?

If it can spin freely, use a Rotating Autotune (preferred)

If it cannot spin freely, use a Stationary Autotune
Action Requirements
Rotating Autotune
Preferred method
Spins the motor up to
the maximum speed
set by the user to
identify all necessary
motor characteristics Motor must spin freely during Autotune
Stationary Autotune
Only used when the
motor cannot spin
freely during the
Autotune feature
Motor does not spin
during Autotune. A
limited set of motor
characteristics are
identified You must enter the correct value of
magnetising current
Do not subsequently operate the drive above
base speed
Necessary Data
You MUST enter values for the following parameters before an Autotune can be carried out:
MOTOR CURRENT
BASE FREQUENCY
MOTOR VOLTAGE
(maximum motor output voltage)
NAMEPLATE RPM (motor nameplate speed)
MOTOR POLES (the number of motor poles)
Performing a Rotating Autotune
Check that the motor can rotate freely in the forward direction. Ensure also that the motor is
unloaded. Ideally, the motor shaft should be disconnected. If the motor is connected to a gearbox
this is ok, provided that there is nothing on the output of the gearbox which could load the
motor.
1. Set MAX SPEED (
P
2) to the maximum speed at which you will operate the drive in normal
operation. The Autotune will characterise the motor up to 30% above this speed. If you
later wish to run faster than this, you will need to carry out another Autotune.
2. Set the AUTOTUNE MODE (S CL20) parameter to ROTATING(1).
3. Set AUTOTUNE ENABLE (
S
CL21) to 1 (TRUE), and start the drive. The drive will carry
out a Rotating Autotune, indicated by the Run and Stop led’s flashing on the blank cover
when fitted, or by flashing
on the keypad. This may take several minutes, during
which the motor will be accelerated to maximum speed and then brought to a stop. When
complete, the drive is returned to the stopped condition and the AUTOTUNE ENABLE
parameter is reset to 0 (FALSE).
Performing a Stationary Autotune
Before starting the stationary Autotune, you MUST enter the value of magnetising current for
the motor (
S
CL14). This may be available on the motor nameplate. If not, you may need to
contact the motor supplier.
1. Set the AUTOTUNE MODE (S CL20) parameter to STATIONARY(0).
2. Set AUTOTUNE ENABLE (
S
CL21) to 1 (TRUE), and start the drive. The drive will carry
out a Stationary Autotune, injecting current into the motor but not turning the shaft. The
Run and Stop led’s will flash on the blank cover when fitted, or
will flash on the
keypad. When complete, the drive is returned to the stopped condition and the AUTOTUNE
ENABLE parameter is reset to 0 (FALSE).
