e 117 [V Imbalance Time]
Sets the time delay in detecting a voltage imbalance between phases. A fault or
alarm may be generated if the calculated imbalance is greater than the limit set
by parameter 116 - [V Imbalance Limit] for this amount of time.

[PWM Frequency]
Sets the PWM carrier frequency. The value is entered in kHz. When the power
structure allows more than one setting for the carrier frequency, the power must
be cycled off/on to have the new value take effect.
