AC30 series Variable Speed Inverter
Minimum 2kHz (default)
Maximum 8kHz
Derating of output current will apply above the default switching frequency.
Maximum is Switching Frequency divided by 8. This is limited to 590Hz due to export rules.
e.g. for 2kHz switching frequency it is 2000/8 = 250Hz
Maximum is Switching Frequency divided by 6, in PMAC Motor Closed Loop Control.
If >590Hz is required, please contact your local Parker Sales representative.
