Procedure
1. Determine the following values using the motor data sheet:
– Set the current value of the saturation characteristic iq[0] ... iq[4].
– Determine the flux values psiq[0] ... psiq[4] associated with the current values.
Figure 7-9
If the saturation characteristic of the third-party motor is not available, leave parameters
p356 and p362 ... p369 in their factory settings.
Commissioning usually leads to a satisfactory control behavior only with a correctly set
saturation characteristic.
2. Set p0356 = psiq[0] / (20 % · p0305)
3. Set the following parameters:
– p0362 = psiq[1] / (p0356 · p0305) · 100 %
– p0363 = psiq[2] / (p0356 · p0305) · 100 %
– p0364 = psiq[3] / (p0356 · p0305) · 100 %
– p0365 = psiq[4] / (p0356 · p0305) · 100 %
– p0366 = iq[1] / p0305 · 100 %
– p0367 = iq[2] / p0305 · 100 %
– p0368 = iq[3] / p0305 · 100 %
– p0369 = iq[4] / p0305 · 100 %
Alternatively, you can calculate parameters p0362 ... p0365 based on inductances L1 ... L4:
– p0362 = L1 / p0356 · p0366
– p0363 = L2 / p0356 · p0367
– p0364 = L3 / p0356 · p0368
– p0365 = L4 / p0356 · p0369
