Corrected from:
Inverter Drives 8400 StateLine V16.00.00
Inverter Drives 8400 HighLine V16.00.00
Inverter Drives 8400 TopLine V16.00.00
Response of the new version:
No vibrations in the speed range higher than 650 Hz.
What happens?
Motor vibrations in the speed monitoring range.
When does this behaviour occur?
The behaviour occurs when selecting a frequency C0059 > 650Hz in the SLPSM control mode and travelling in this speed range.
Which products are affected?
Inverter Drives 8400 StateLine FW V14.00.00/V15.00.00
Inverter Drives 8400 HighLine FW V14.00.00/V15.00.00
Inverter Drives 8400 TopLine FW V14.00.00/V15.00.00
Short-term measures:
Reduce the PLL gain C0999 for fdmax=C0059 by factor 2
Evaluation/recommendations:
The vibrations may lead to high currents and voltages. High speed accuracy is no longer given.
