Auto-Tuning for PM Motors

The following explains the method of Auto-Tuning for PM motors. Set the following parameters for Auto-Tuning.
• Motor parameters E1-xx, E5-xx
• Speed feedback detection-use F1-xx (only with Closed Loop Vector Control method for PM)

Table 3.9 Auto-Tuning for PM Motors
Applicable When/Advantages
• When information from the motor's test report or
nameplate is available.
• Rotational/Stationary Auto-Tuning that
energizes the motor is not carried out. Manually
input the necessary motor parameters.
• When information from the motor's test report or
nameplate is not available.
Note:
With Stationary Auto-Tuning, the drive remains
stopped while it is energized for about 1 minute.
During this time the necessary motor
parameters are automatically measured.
• After Auto-Tuning was carried out, the wiring
distance between the drive and motor changed
by 50 m or more.
• When the motor output and drive capacity are
different.
