Question:
Can, in case of vector control, a different setting of code C0086 modify the drive behaviour although all motor data are set identically (C0081, C0087, C0088, C0089, C0090 und C0091)?
Answer:
Yes. In operating mode vector control (C0006 = 1) code C0086 influences the magnetising current Iµ and consequently the calculation of the internal motor parameters.
- C0086 > 0 always means LENZE motor --> Magnetising current is taken from a Lenze motor parameter table.
- C0086 = 0 always means third party motor --> Magnetising current is calculated from the entered motor data.
The applied magnetising current also influences the calculation of the internal motor parameters during identification (C0148) run. Consequently, the setting C0086 modifies the vector control / the drive behaviour (it becomes obvious e. g. by a different open circuit power consumption or a different smooth running).
A permanent drive behaviour can only be obtained, when all motor data (C0086 included) are identical. In this case code C0086 can be considered as a name plate indication.
