292 Parameters9595 HW configuration Various hardware-related settings.95.01 Supply voltage Selects the supply voltage range. This parameter is usedby the drive to determine the nominal voltage of the supplynetwork. The parameter also affects the current ratingsand the DC voltage control functions (trip and brakechopper activation limits) of the drive.WARNING! An incorrect setting may cause themotor to rush uncontrollably, or the brake chopperor resistor to overload.Note: The selections shown depend on the hardware ofthe drive. If only one voltage range is valid for the drive inquestion, it is selected by default.Automatic /not selectedAutomatic / notselectedNo voltage range selected. The drive will not startmodulating before a range is selected, unless parameter95.02 Adaptive voltage limits is set to Enable, in whichcase the drive estimates the supply voltage itself.0200…240 V 200…240 V, available for ACS380-04-xxxx-1 drives 1380…480 V 380…480 V, available for ACS380-04-xxxx-4 drives 295.02 Adaptive voltage limits Enables adaptive voltage limits.Adaptive voltage limits can be used if, for example, anIGBT supply unit is used to raise the DC voltage level. Ifthe communication between the inverter and IGBT supplyunit is active, the voltage limits are related to the DCvoltage reference from the IGBT supply unit. Otherwisethe limits are calculated based on the measured DCvoltage at the end of the pre-charging sequence.This function is also useful if the AC supply voltage to thedrive is high, as the warning levels are raised accordingly.EnableDisable Adaptive voltage limits disabled. 0Enable Adaptive voltage limits enabled. 195.03 Estimated AC supplyvoltageAC supply voltage estimated by calculation. Estimation isdone every time the drive is powered up and is based onthe rise speed of voltage level of the DC bus while thedrive charges the DC bus.-0.0…1000.0 V Voltage. 10 = 1 V95.04 Control board supply Specifies how the control board of the drive is powered. Internal 24VInternal 24V The drive control board is powered from the drive powerunit it is connected to.0External 24V The drive control board is powered from an externalpower supply.195.15 Special HW settings Contains hardware-related settings that can be enabledand disabled by toggling the specific bits.Note: The installation of the hardware specified by thisparameter may require derating of drive output, or imposeother limitations. Refer to the hardware manual of thedrive.-No. Name/Value Description DefaultFbEq 16
