Corrected from:
Inverter Drives 8400 StateLine, HighLine, and TopLine from firmware version 14.00.00.00
Response of the new version?
The recording and transfer of the rotor displacement angle to the motor control has been improved. With activation of the current controller feedforward control (C079), jitter-free operation up to 1000Hz is possible for SC-PSM.
Which products are affected?
Inverter Drives 8400 StateLine, HighLine, and TopLine with a firmware version lower than 14.00.00.00
What happens?
The synchronous machine jitters at very high output speeds.
When does the problem occur?
If the SC-PSM control mode is set and at an output speed higher than approx.700Hz. Activation of the current controller feedforward control (C079/1) does not provide any improvement either.
Short-term measures/recommendations?
None
Evaluation:
For operation of a motor in SC-PSM control mode with a setpoint speed higher than 700 Hz, a FW update must be carried out.
