5.4.3 Reference Pulse Input Multiplication Switching Function

The input multiplier for the position reference pulses can be switched between 1 and n (n = 1 to 100) by turn-

ing the Reference Pulse Input Multiplication Switching Input signal (/PSEL) ON and OFF. The Reference

Pulse Input Multiplication Switching Output signal (/PSELA) can be used to confirm that the multiplier has
been 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).

(3) Input Signal Setting

Use 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 to

Input 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 position

reference pulse.

• If changing the setting of Pn218, disconnect the servomotor shaft from the machine and perform trial oper-

ation. Be sure that no problems will occur before connecting the shaft to the machine again.
