(1)These power ratings are for a switching frequency of 4 kHz, in continuous operation. The
switching frequency is adjustable from 2 to 16 kHz.
Above 4 kHz, the drive will reduce the switching frequency if an excessive temperature rise
occurs. The temperature rise is detected by a probe in the power module. Nonetheless,
derating should be applied to the nominal drive current if continuous operation above 4 kHz
is required:
• 10% derating for 8 kHz
• 20% derating for 12 kHz
• 30% derating for 16 kHz
