292 Parameters
95
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.
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.
Automatic /
not selected
Automatic / not
selected
No voltage range selected. The drive will not start
modulating before a range is selected, unless parameter
95.02 Adaptive voltage limits is set to Enable, in which
case the drive estimates the supply voltage itself.

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 IGBT supply
unit is active, the voltage limits are related to the DC
voltage reference from the IGBT supply unit. 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.

Disable Adaptive voltage limits disabled. 0
Enable Adaptive voltage limits enabled. 1
95.03 Estimated AC supply
voltage
AC supply voltage estimated by calculation. Estimation is
done every time the drive is powered up and is based on
the rise speed of voltage level of the DC bus while the
drive charges the DC bus.

95.04 Control board supply Specifies how the control board of the drive is powered. Internal 24V
Internal 24V The drive control board is powered from the drive power
unit it is connected to.
0
External 24V The drive control board is powered from an external
power supply.

95.15 Special HW settings Contains hardware-related settings that can be enabled
and disabled by toggling the specific bits.
Note: The installation of the hardware specified by this
parameter may require derating of drive output, or impose
other limitations. Refer to the hardware manual of the
drive.
