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 In
put 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 po
sition reference pulse is 0. If the position refer-
ence pulse is not 0 when the multiplier is switch
ed, 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).

(2) Timing Chart for Reference Pulse Input Multiplication Switching
(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, be sure that no problems will occur upon operation before configuring the
servomotor and other parts of the machine system.
