Inovance MD320 Series - Group F1 Motor Parameters

MD320/MD320N User Manual Parameter Description
101
Two PWM carrier frequency adjustment modes, xed and random, are provided. The random
PWM motor noise has wide frequency range, while the fixed PWM motor noise has fixed
frequency.
When the carrier wave temperature adjustment is active, the inverter can automatically adjust
the carrier frequency according to its temperature. This function can reduce the possibility of
overheating alarm of the inverter.

Speed-up time 1 refers to the time “t1” required for the inverter to speed up from 0Hz to the
maximum output frequency (F0-10).
Speed-down time 1 refers to the time “t2” required for the inverter to Speed down from the
maximum output frequency (F0-10) to 0Hz, as shown in the following gure:
