94.41 Power gen limit on
net loss
Defines the maximum shaft power for generating upon a
supply network failure when supply unit control is active (bit 11
or 15 of 95.20 HW options word 1 is on).
The value is given in percent of nominal motor power.
-600.00%
-600.00 … 0.00% Maximum shaft power for generating mode upon a supply
network failure.

95 HW configuration
Various hardware-related settings.
95.01 Supply voltage Selects the supply voltage range. This parameter is used by
the drive to determine the nominal voltage of the supply
network. The parameter also affects the current ratings and
the DC voltage control functions (trip and brake chopper
activation limits) of the drive.
WARNING! An incorrect setting may cause the motor
to rush uncontrollably, or the brake chopper or resistor
to overload.
Notes:
• The selections shown depend on the hardware of the drive.
If only one voltage range is valid for the drive in question, it
is selected by default.
• This parameter cannot be changed while the drive is
running.
-
Not given No voltage range selected. The drive will not start modulating
before a range is selected.

95.02 Adaptive voltage
limits
Enables adaptive voltage limits.
Adaptive voltage limits can be used if, for example, an IGBT
supply unit is used to raise the DC voltage level. If the
communication between the inverter and the IGBT supply unit
is active (95.20 HW options word 1), the voltage limits are
related to the DC voltage reference transmitted to the supply
unit (94.20 DC voltage reference) assuming that the reference
is high enough. Otherwise, the limits are calculated based on
the measured DC voltage at the end of the pre-charging
sequence.
This function is also useful if the AC supply voltage to the
drive is high, as the warning levels are raised accordingly.

95.04 Control board
supply
Specifies how the control unit of the drive is powered.
The default value depends on the type of the control unit and
the setting of parameter 95.20.
Internal 24V
(ZCU);
External 24V
(BCU;
95.20 b4)
Internal 24V The drive control unit is powered from the drive power unit it is
connected to.
Note: If reduced run (see page 93) is required, select External
24V or Redundant external 24V instead.
