UV Alarm Level
[A402]
(Undervoltage Alarm Level)
The nominal DC bus voltage is
equal to 1.414 times the input line-
to-line voltage (i.e. 1.414*Input L-L
Volts (A4) ). This parameter sets the
level (as a percentage of the
nominal DC bus voltage) at which
an undervoltage alarm will be
declared.

PWM
Frequency
[A404]
(Carrier Frequency)
This parameter sets the PWM or
‘carrier’ frequency of the drive. The
carrier is defaulted at 10.0 kHz,
which is well out of audible range.
The drive does not derate when the
PWM frequency is set to 10kHz or
below.
For more information on
derating see page 16.

Id Reg Diff Gain
[A406]
(Current Regulator Differential Gain
for Flux Generation)
The differential gain for the current
regulator flux generation. This
parameter is meant for advanced
operation; therefore, the parameter
will rarely need to be changed from
the default value.
