Control connection37 04/2019 - V01 DS 400.2Safety input RFE (rotating field enable) 5.2 Safety input RFE (rotating field enable)Stopp-Class 0Warning!If the input of the enable or of the rotating field enable areswitched off, the drive is free of torque. The drive could move ifthere is no mechanical brake or block provided.The motor conductors are not dead. Only the rotating field isdisabled. Prior to any work or maintenance on the motor orservo-drive, the servo-drive must be completely disconnectedfrom the mains power supply.Operation with RFE inputDS-BAxDPC/E-DS-400-REF-1-1/1-2/1-3Two-channel disable of the enable via asafety switching device.Enable input FRG/RUN + rotating fieldenable input RFESwitching onContacts of the safety device closed.Enable FRG/RUN 0.5s after RFESafety switch-offContacts of the safety device open:There is no FRG/RUN signal in the 1 st disablechannel to disable the PWM pulses in theprocessor,There is no RFE signal in the 2 nd disablechannel to disable the PWM pulses atthe output of the processor.RestartRelease the safety switching device.Contacts of the safety device closed.The motor can only move after a seconddisable FRG/RUN (after the rotating fieldenable RFE).Operation without RFE inputThe input RFE must be bridged with thelogic voltage.If the logic voltage corresponds to thesupply voltage, the RFE input is bridgedwith +24V.Enable FRG/RUN at least 0.5s after the RFEsignal.212019181716151413121110987654321CNC/SPSHardwarePNOZHardwareFRG / RUNRFE+24V=GND24X1DSxx, BAxxGNDEGND24+24V=+24GND24EnableSafityDeviceEnableRotationenableLogic-GND24V- Voltage212019181716151413121110987654321CNC/SPSHardwarePNOZHardwareFRG / RUNRFE+24V=GND24X1DSxx, BAxxGNDEEnableSafityDeviceEnableRotationenableLogic-GNDLogik - Voltage212019181716151413121110987654321CNC/SPSHardwareHardwareFRG / RUNRFE+24V=GND24X1DSxx, BAxxGNDEEnableEnableRotationenableLogic-GNDLogic - Voltage
