5 DATA USED FOR POSITIONING CONTROL
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.

Pr.5 Pulse output mode
Set the pulse output mode to match the servo amplifier being used.
IMPORTANT
The only valid value of the "
when the PLC READY signal [Y0] turns from OFF to ON for the first time after the
power is switched ON or the CPU module is reset. Once the PLC READY signal
[Y0] has been turned ON, the value will not be reset even if another value is set to
the parameter and the PLC READY signal [Y0] is turned from OFF to ON.
Pr.23
Use " Output signal logic selection" to choose between the positive logic
(pulse rising edge detection) and negative logic (pulse falling edge detection).
An example of the pulse output mode for positive and negative logic is shown
below.
