How to carry out automatic motor parameter identification:
1. Inhibit the controller if it is enabled, e.g. via the C00002/16 device command or a LOW
signal at the RFR terminal.
2. Wait until the drive is at standstill.
3. Transfer the nameplate data to the following codes:
• C00081 : Rated motor power
• C00087 : Rated motor speed
• C00088 : Rated motor current (according to the connection method /)
• C00089 : Rated motor frequency (according to the connection method /)
• C00090 : Rated motor voltage (according to the connection method /)
• C00091 : Motor cos ϕ
4. Start motor parameter identification via the C00002/23 device command.
5. Enable the controller again.
• Motor parameter identification starts.
• The motor parameter identification takes approx. 30 s.
• The identification is completed if the "0: Off / ready" message is displayed in
C00002/23 .
6. Inhibit controller again.

Note!
Motor parameter identification may be aborted by the controller if a special motor (e.g.
mid-frequency motor) is used or if there is a large deviation between inverter and motor
power.
Another cause for the abort of the motor parameter identification could be the
implausibility of the entered nameplate data, e.g. the entry P = 0 kW for the motor
power.
