Stationary or Rotating Autotune?
Will the motor spin freely, i.e. not connected to a load, during the Autotune?


Necessary Data
You MUST enter values for the following parameters before an Autotune can be carried out:
MOTOR CURRENT
BASE FREQUENCY
MOTOR VOLTAGE
NAMEPLATE RPM
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 (
2. Set the AUTOTUNE MODE (S CL20) parameter to ROTATING(1).
3. Set AUTOTUNE ENABLE (
Performing a Stationary Autotune
Before starting the stationary Autotune, you MUST enter the value of magnetising current for
the motor (

1. Set the AUTOTUNE MODE (S CL20) parameter to STATIONARY(0).
2. Set AUTOTUNE ENABLE (
