Open collector output is also available for phase Zand EXZ signals.Communication function(USB) Personal computer, etc. can be connected for parameter setting configuration and statusmonitoring.Front panel ①7 seg LED 2pcs ②RSW 1pcsRegeneration External resistorBasic SpecificationDynamic brake ProvidedControl input Deviation counter clear, command pulse input inhibition, electronic gear switching,damping control switching, etc.Control output In-position, etc.Maximum commandpulse frequency 500 kppsInput pulse train Differential input; parameter-selectable (1) Positive/Negative 2) Phase A/Phase B 3)Command/Direction)Command scaling(electric gear ratiosetting)1/1000 - thousandfoldEncoder resolution (numerator) and command pulse count per motor revolution (de-nominator) can be arbitrarily specified between 1-220 for numerator and 1-220 for de-nominator but use within the range above.Input pulseSmoothing filter Selectable between first order filter and FIR filter for command input.Position controlDamping control AvailableAuto tuning Identifying load inertia real-time and automatically setting gain that meets set stiffnesswhen the motor is driving by a operation command from the host or driveDividing encoder pulse Pulse count can be arbitrarily specified (up to encoder pulse count).Protective functionOvervoltage, undervoltage, overspeed, overload, overheat, overcurrent,encoder abnormalitiesPosition deviation fault, Command pulse division, EEPROM error, etc.FunctionCommonAlarm data trace back function Alarm data history can be viewed.
