Precautions on auto-tuning
(1) Conduct auto-tuning only after the motor has been connected and operation completely stopped.
If auto-tuning is conducted immediately after operation stops, the presence of a residual voltage
may result in abnormal tuning.
(2) Voltage is applied to the motor during tuning even though it barely rotates. During tuning,

(3) Tuning is performed when the motor starts for the first time after
Tuning is usually completed within three seconds. If it is aborted, the motor will trip with the dis-
play of and no constants will be set for that motor.
(4) High-speed motors, high-slip motors or other special motors cannot be auto-tuned. For these
motors, perform manual tuning using Selection 2 described below.
(5) The resulting insufficient motor torque during tuning could create a risk of machine stalling/falling.
