108Parameter DescriptionDetermines how the emergency power function is activated. The emergencypower function allows the drive to run off of a UPS or battery back upsystem, 460V units can be run from a 230V 1 phase supply. 230V unitscan be run from a 230V 1 phase supply.When active the under voltage fault level is reduced to 160VAC. The inputphase failure detection is shut off, and the torque limit is reduced to therated torque of the motor.If a speed is programmed for this function, then whenever the speed isselected, the drive automatically goes into emergency operation. If thefunction is triggered by a digital input (X2A.10), the input must be activewhen the drive is enable and must remain active for at least one second.Settings: Off = no functionSPd1 = Intermediate speed one serves as the emergencyoperation speed.SPd2 = Intermediate speed two serves as the emergencyoperation speed.SPd3 = Intermediate speed three serves as the emergencyoperation speed.di 1 = Digital input X2A.10 activates the emergency operation(This mode is not possible if LF.57 =2)Note: If a 460V unit is being powered from a 230V UPS system, themaximum car speed can be 50% of contract speed. Higher speedswill result in loss of control due to low DC bus voltageA setting of SPd1, SPd2 or SPd3 can not be used if the one floorpositioning function (LP.1 = P onE) of the drive is activated.iEmergency operationmode
