[Pr.5] Pulse output mode
Set the pulse output mode to match the servo amplifier used.
The only valid value of [Pr.5] Pulse output mode is the value at the moment when PLC READY signal [Y0] is
turned off and on for the first time after the power is switched on or the CPU module is reset. Once PLC
READY signal [Y0] is turned on, the value will not be reset even if another value is set to the parameter and
PLC READY signal [Y0] is turned off and on.
Use [Pr.23] Output signal logic selection to choose between the positive logic (pulse rising edge detection) and negative logic
(pulse falling edge detection). For the output specifications of each pulse output mode, refer to the following.

MELSEC iQ-R Positioning Module User's Manual (Startup)
The following shows examples of the pulse output modes for positive and negative logic.
■
PULSE/SIGN mode
■
CW/CCW mode
During forward run, the forward run feed pulse (PULSE F) is output.
During reverse run, the reverse run feed pulse (PULSE R) is output.
Pulse output mode Setting value
PULSE/SIGN mode 0
CW/CCW mode 1
A phase/B phase mode (multiple of 4) 2
A phase/B phase mode (multiple of 1) 3
Positive logic Negative logic
Forward run and reverse run are controlled with the on/off of the direction sign
(SIGN).
The motor will forward run when the direction sign is HIGH.
The motor will reverse run when the direction sign is LOW. Forward run and reverse run are controlled with the on/off of the direction sign
(SIGN).
The motor will forward run when the direction sign is LOW.
The motor will reverse run when the direction sign is HIGH.
