Auto-Tuning for Permanent Magnet Motors
Note:
PM motor control modes are not available on 600 V class drives, CIMR-Ao5oooooooo.
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.

T2-01 = 0
• Motor does not rotate during Auto-Tuning.
• Motor test report or motor data similar to Table 4.18 are
available.

T2-01 = 2
• 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.
YES YES YES
Z Pulse Offset Tuning T2-01 = 3
• PG encoder has been replaced. Calculates the Z Pulse offset.
• Requires the motor to rotate with no load or very low load.
– – YES
Table 4.18 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 95 for details on the Auto-Tuning process and selection.
