6.8 Manual Zero-adjustment of Analog Monitor Output (Fn00C)6-156 Utility Functions (Fn)6.8 Manual Zero-adjustment of Analog Monitor Output (Fn00C)This function is used to manually adjust the offsets for the analog monitor outputs (force reference monitoroutput and motor speed monitor output). The offsets for the force reference monitor output and motor speedmonitor output can be adjusted individually. The offset values are factory-set before shipping. Therefore, theuser need not usually use this function.(1) Adjustment ExampleAn example of offset adjustment to the motor speed monitor is shown below.• Offset adjustment cannot be made if write protection is set in Fn010.• The adjustment value will not be initialized when parameter settings are initialized using Fn005.• Make offset adjustment with a measuring instrument connected, so that the analog monitor output is zero.An example of settings for a zero analog monitor output is shown below.• While the motor is not turned ON, set the monitor signal to the force reference.• In speed control, set the monitor signal to the position error.(2) Operating ProcedureFollow the steps below to perform the manual zero-adjustment of analog monitor output.Item SpecificationsZero-adjustment Range -2 V to + 2 VAdjustment Unit 18.9 mV/LSBAnalog monitor outputvoltageMotor speedOffsetaddjustmentStep Display Example Keys Description1 Press the Key to open the Utility Function Modemain menu and select Fn00C.2Press the Key.The display is switched to the execution display ofFn00C.Note: If the display is not switched and "NO-OP" isdisplayed in the status display, the Write Prohib-ited Setting (Fn010 = 0001) is set.
