Automatic calculation of the field weakening controller parameters for ASM servo control
From version 15.00.00 , the field weakening controller parameters are automatically calculated as
well after a successful motor parameter identification. Moreover, the special functions of the
internal motor control listed in the table are activated.
• If these parameters are not to be calculated/activated, bit 6 has to be set to "1" in C02864/1 .
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 .)
From version 15.00.00:
11. If C02864/1 - bit 6 = "0" (Lenze setting):
The field weakening controller parameters are calculated and certain special functions of the
internal motor control are activated. (See table .)

Activation of special functions of the internal motor control
C02864/1 Bit 5 is set to "1"
 Field/field weakening controllers are called in a 500-μs cycle.*

Bit 7 is set to "1"
 In case of servo control for asynchronous motors, the rated motor
speed ( C00087 ) is assumed for the calculation of the slip from the
nameplate ( C02879 /bit 1 = "0".*
