The ReferencePulse Input Multiplication Switching Output signal (/PSELA) can be used to confirm that the multiplier hasbeen switched.To use this function, set the multiplier in Pn218.Switch the multiplier of the reference pulse only when the position reference pulse is 0. If the position refer-ence pulse is not 0 when the multiplier is switched, the servomotor position may shift.Note: The reference pulse input multiplication switching function is supported by software version 001A or later. The soft-ware version can be checked with Fn012. For details, refer to 7.14 Software Version Display (Fn012).(1) Related Parameter(2) Timing Chart for Reference Pulse Input Multiplication Switching(3) Input Signal SettingUse the /PSEL signal when switching to the multiplier of the input reference pulse that is set in Pn218.Note: Use parameter Pn515.1 to allocate the /PSEL signal for use. For details, refer to 3.3.1 Input Signal Allocationss toInput Terminals.CAUTION• Unexpected operation may occur if a position reference pulse is input before the multiplier changes.Always use the /PSELA signal to confirm that the multiplier has been switched before inputting a positionreference pulse.• If changing the setting of Pn218, be sure that no problems will occur upon operation before configuring theservomotor and other parts of the machine system.Pn218Reference Pulse Input Multiplication ClassificationSetting Range Setting Unit Factory Setting When Enabled1 to 100 1 time 1 Immediately SetupPosition×1 ×n(n = Pn218) ×1EnabledEnabledDisabledDisabledSERVOPACK internal status4 ms or less 4 ms or lessReference Pulse InputMultiplication Switching Input signal (/PSEL)Reference Pulse InputMultiplication Switching Output signal (/PSELA)AnalogType SignalNameConnectorPin Number Setting MeaningInput /PSEL Must be allocated ON (closed) Enables the multiplier of the input reference pulse.OFF (open) Disables the multiplier of the input reference pulse.
