Code Name Setting range Default Min. Attri.
C1.23 Leakage inductance 0.00...200.00 mH DOM 0.01 Stop
C1.24 Mutual inductance 0.0...3,000.0 mH DOM 0.1 Stop
For the applications with higher performance requirement in V/f control, motor
parameter auto-tuning is necessary.
The actual no-load current is limited to be less than 75 % of the motor rated cur-
rent.
Example
[C1.07] = 2.06, then set [C1.20] = 2.06, the actual setting value is 1.54.
[C1.07] = 655.00, then set [C1.20] = 655.00, the actual setting value is 491.22.
The application level and setting order of motor parameters
As shown in the table below, the motor control parameters are divided into 4 ap-
plication levels that are interrelated on certain computational basis. In the proc-
ess of parameter setting, the level attribute is a defining factor for the setting of
the parameter value.
Code Name Level
C1.01 Motor parameter tuning Top level
C1.05 Motor rated power
Nameplate level
C1.06 Motor rated voltage
C1.07 Motor rated current
C1.08 Motor rated frequency
C1.09 Motor rated speed
C1.10 Motor rated power factor
C1.12 Motor rated slip frequency
Physical parameter level
C1.20 Motor no-load current
C1.21 Stator resistance
C1.22 Rotor resistance
C1.23 Leakage inductance
C1.24 Mutual inductance
C2.43 Current limitation proportional gain
Control parameter level
C2.44 Current limitation integral time
Tab. 12-14: The application level of motor parameters
The user shall follow the order as specified below to set or modify the parame-
ters, Top level -> Nameplate level -> Physical parameter level -> Control parame-
ter level.
If the user does not conform to the order as specified above, this would cause
undesired change to the parameter setting.
