5 Operation5.4.2 Clear Signal Setting5-345.4.2 Clear Signal SettingThe clear input signal sets the error counter in the multi-winding drive unit to zero.(1) Connecting the Clear Signal(2) Clear Input Signal FormSet the clear input signal form using Pn200.1.The following items will be changed in the multi-winding drive unit after the error counter has been reset tozero.• The error counter in the multi-winding drive unit is set to 0.• The position loop operation is disabled.Note: Holding the clear status may cause the servolock to stop functioning and the servomotor to rotate slowly due to driftin the speed loop. Pulse Width of Clear SignalWhen parameter Pn200.1 is set to 0 or 2, the width of the clear signal must be at least 250 μs to reset the errorcounter.When parameter Pn200.1 is set to 1 or 3, the width of the clear signal must be at least 20 μs to reset the errorcounter.(3) Clear OperationThis parameter determines when the position error should be set to zero according to the condition of themulti-winding drive unit. Any of three clearing modes can be selected with Pn200.2.Type Signal Name Connector Pin Number NameInput CLR CN1-15 Clear input/CLR CN1-14Parameter Description Clear Timing WhenEnabled ClassificationPn200n.0[Factory setting]Clears at ON.Position errors do notaccumulate while the sig-nal is ON.After restart Setupn.1 Clears at the rising edge.n.2Clears at OFF.Position errors do notaccumulate while the sig-nal is OFF.n.3 Clears at the falling edge.Clears atON.CLR(CN1-15)ONClears here just once.CLR(CN1-15)OFF.CLR(CN1-15)Clears atOFFClears here just once.CLR(CN1-15)Parameter Description WhenEnabled ClassificationPn200n.0[Factory setting]Sets the position error to zero during a baseblock whenan alarm occurs or when the servo ON signal (/S-ON)turns OFF.After restart Setupn.1 Does not set the error counter to zero. Clears the posi-tion error only with the CLR signal.n.2 Sets the position error to zero when an alarm occurs.
