Principal sequence of the motor parameter identification

1. The motor stator resistance (

C00084

) is measured.

2. The inverter error characteristic is measured.
3. The motor stator leakage inductance (

C00085

) is measured.

4. The V/f base frequency (

C00015

) is calculated.

5. The slip compensation (

C00021

) is calculated.

6. The V

min

boost (

C00016

) is detected.

7. Only for asynchronous motors:

The motor magnetising inductance (

C00092

) and the motor rotor resistance (

C00082

) are

measured.
The motor magnetising current (

C00095

) is measured.

From version 12.00.00:

8. If

C02865/1

- bit 4 = "0" (Lenze setting):

The current controller and field controller parameters are calculated. (See

table

.)

9. If

C02865/1

- bit 5 = "1":

The speed controller parameters are calculated. (See

table

.)

10. If

C02865/1

- bit 6 = "1":

Other controller parameters are calculated. (See

table

.)

Selection of the identification mode

From version 10.00.00 onwards

, two identification modes are available in

C02867/1

:

• "1: Basic identification" (previous mode)

• Only for asynchronous motors
• Duration approx. 30 s

• "2: extended identification"

• Stands out due to increased accuracy of the determined motor parameters.
• Also supports synchronous motors and asynchronous motors with a power of more than 11

kW.

• Duration approx. 80 s

Tip!
In the Lenze setting, a setting of "0: automatic" is selected in

C02867/1

. This setting ensures

that the controller automatically selects the optimum procedure for motor parameter

identification.
