3.6 Detailed explanation of signals
3.6.1 Position control mode
POINT
Adjust the logic of a positioning module and command pulse as follows.
MELSEC iQ-R series/MELSEC-Q series/MELSEC-L series positioning
module
Signal type
Command pulse logic setting
Positioning module
Pr. 23 setting
MR-JE-_A servo amplifier
[Pr. PA13] setting
Open-collector type
Positive logic
Positive logic (_ _ 0 _)
Negative logic
Negative logic (_ _ 1 _)
Differential line driver type
Positive logic (Note)
Negative logic (_ _ 1 _)
Negative logic (Note)
Positive logic (_ _ 0 _)
Note.
For MELSEC iQ-R series/MELSEC-Q series/MELSEC-L series, the logic means N-side
waveform. Therefore, reverse the input pulse logic of the servo amplifier.

(1) Pulse train input
(a) Input pulse waveform selection
You can input command pulses in any of three different forms, and can choose positive or negative
logic. Set the command pulse train form in [Pr. PA13]. Refer to section 5.2.1 for details.

For source input interface
Note. Pulse train input interface is comprised of a photocoupler.
If a resistor is connected to the pulse train signal line, it may malfunction due to reduction in current.
