General Power Stack Features:
Switching Frequency:
Minimum: 1kHz
Default:
- Frames 2 – 6: 4kHz
- Frame 7: 3kHz
- Frames 8 – 10: 2kHz
Maximum:
- Frames 2 – 6 (1.5 – 37kW): 10kHz

Linear derating of output current will apply above the default switching
frequency (varies by power rating. Refer to Chapter 13: Technical
Information for values).
Output Frequency:
Induction Motors:
- Maximum = Switching Frequency ÷ 8
PMAC Motors:
- Maximum = Switching Frequency ÷ 6
Note: Output frequency is limited to a maximum frequency of 590Hz
due to export rules.
