(2) PLS/SIGN
Input the pulse signal for counting the increased/decreased pulse in the
pulse input (PLS). Input the signal for controlling forward run and reverse
run in the direction sign (SIGN).

Input signal logic selection
" is positive logic
• The motor will forward run when the direction sign is HIGH.
• The motor will reverse run when the direction sign is LOW.
2) "
Pr.22
Input signal logic selection
" is negative logic
• The motor will forward run when the direction sign is LOW.
• The motor will reverse run when the direction sign is HIGH.

External command/
Switching signal
(DI1) 11 • Input a control switching signal during speed-position or position-speed
switching control.
• Use this signal as the input signal of positioning start, speed change request,
skip request and mark detection from an external device.
Set the function to use this signal in "
Pr.42
External command function selection
".
(Note-1): Set the signal in "
Pr.95
External command signal selection
" at
LD77MS16 use.
(Note-2): There are no signals of DI3 and DI4 at LD77MS2 use.

• Common for external command/switching signals.
Forced stop input signal (EMI) 10 • This signal is input when batch forced stop is available for all axes of servo
amplifier.
EMI ON (Opened)
: Forced stop
EMI OFF (24VDC input) : Forced stop release
