Various hardware-related settings.HW configuration95
- / uint16Selects the supply voltage range. This parameter is
used by the drive to determine the nominal voltage of
Supply voltage95.1
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.
Note: 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.
Note: This parameter cannot be changed while the
drive is running.
0No voltage range selected. The drive will not start
modulating before a range is selected.

(95.20 b15) / uint16
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.
Adaptive voltage
limits
95.2
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.
