Auto-Tuning for Permanent Magnet Motors
Note: PM motor control modes are not available on 600 V class drives, CIMR-Ao5oooooo.
Automatically sets the V/f pattern and motor parameters E1-oo and E5-oo when a PM motor is used. Additionally, the
feature also sets some F1-oo parameters for speed feedback detection in Closed Loop Vector.

Parameter Tuning
Table 4.30 lists the data that must be entered for Auto-Tuning. Make sure the data is available before starting Auto-Tuning.
The necessary information is usually listed on the motor nameplate or in the motor test report provided by the motor
manufacturer. Also refer to page

Table 4.29 Types of Auto-Tuning for Permanent Magnet Motors
Application Conditions and Benefits
• Motor does not rotate during Auto-Tuning.
• Motor test report or motor data similar to
available.
• A motor test report listing motor data is not available.
• Drive automatically calculates and sets motor parameters.
• Useful to tune the drive when the motor data were set up
manually or by motor code and the cable is longer than 50
m.
• Should also be performed if the cable length has changed
after prior tuning.
• PG encoder has been replaced. Calculates the Z Pulse offset.
• Requires the motor to rotate with no load or very low load.
• Use when a motor test is not available.
• Tunes the motor induction voltage only.
• Should be performed after motor data are set and the encoder
offset is adjusted.
• The motor must be uncoupled from the mechanical system
(remove loads).
