Estimate optimum magnetising current
In case of the given L
h
saturation behaviour, there is (usually) a magnetising current where the
torque efficiency is highest. This magnetising current can be determined by the servo inverter.
•
Executing this function also compresses or extends the L
h
saturation characteristic (inter-
polation points
...
).
•
After the function has been executed, the determined magnetising current is entered in
.
Preconditions for the performance
•
Before this commissioning function is executed, the motor parameters and the L
h
satura-
tion characteristic must be identified
Motor equivalent circuit diagram data
•
The motor must be stalled.
Response of the motor during "standstill" performance
How to estimate the optimal magnetising current:
1
.
Start Axis commands: estimate optimum magnetising current parameter with = 1.
2
.
After the process has been completed, save the changed inverter parameters:
