Reference Pulse Input Multiplication Switching

You can switch the input multiplier for the position reference pulses with the /PSEL (Reference
Pulse Input Multiplication Switch) signal. The number of reference pulses input to the SERVO-
PACK is multiplied by the reference pulse input multiplier. You can change the multiplier from 1
to a specified value n (n can be up to 100). You set the multiplier in Pn218 (Reference Pulse
Input Multiplier).
You can confirm if the multiplier was changed with the /PSELA (Reference Pulse Input Multipli-
cation Switching Output) signal.
This section describes the /PSEL (Reference Pulse Input Multiplication Switch) signal, the refer-
ence pulse input multiplier, and restrictions.
/PSEL (Reference Pulse Input Multiplication Switch) Signal
Use the /PSEL signal to change to the reference pulse input multiplier that is set in Pn218 (Ref-
erence Pulse Input Multiplier).
Type Signal
Input /PSEL
Note: You must allocate the /PSEL signal to use it. You can use the following parameters to allocate the signal to a
terminal.
• Pn50A = n.1 (Change the sequence input signal allocations.)
• Pn515 = n.X (/PSEL (Reference Pulse Input Multiplication Switching Input) Signal Allocation)
Refer to the following section for details.

/PSELA (Reference Pulse Input Multiplication Switching
Output) Signal
You can confirm if the reference pulse input multiplier was changed with the /PSELA (Reference
Pulse Input Multiplication Switching Output) signal.
Type Signal
Output /PSELA
Note: You must allocate the /PSELA signal to use it. You can use Pn510 = n.X (/PSELA (Reference Pulse
Input Multiplication Switching Output) Signal Allocation) to allocate the signal to a terminal. Refer to the fol-
lowing section for details.
6.1.2 Output Signal Allocations on page 6-7
 Always use the /PSELA signal to confirm that the reference pulse input multiplier has been
switched and make sure that there are no position reference pulses before you input a posi-
tion reference.
Unexpected operation may occur if position reference pulses are input before the reference
pulse input multiplier changes.
