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
In Closed-loop Vector Mode set up the
encoder direction parameter
Necessary Data
You MUST enter values for the following parameters, found in the QUICK SETUP menu, before an Autotune can be carried
out:
MOTOR CURRENT
MOTOR BASE FREQ
MOTOR VOLTAGE
(maximum motor output voltage)
NAMEPLATE RPM (motor nameplate speed)
MOTOR POLES (the number of motor poles)
ENCODER LINES (if an encoder is fitted, enter the number of lines used by the encoder)
