Chapter 14 Common Functions
[2] Precautions during parameter setting
(1) When other than "1: External input signal of servo amplifier" and "2: Buffer
memory of LD77MS" is set, the error "External input signal selection error"
(error code: 936) occurs at turning when the PLC READY signal [Y0] ON, and
the READY signal [X0] is not turned ON.
[3] Control details
The following table shows the external signal that becomes valid by setting
"
Pr.80
External input signal selection
".
"

[4] Program example
The following shows the program example that is used to operate "
Cd.44
External input signal operation device
" of axis 1, axis 4, axis 8, and axis 16 using
the limit switch connected to the input module when "2: Buffer memory of
LD77MS" is set in "
Pr.80
External input signal selection
".
