２.６.６ Setting the Command Pulse Logic
When carrying out positioning in the forward and reserve rotation pulse train setting for the MR-J4-_A_ servo
amplifier, it is necessary to adjust the command pulse logic of the positioning module to that of the servo amplifier.
Set as follows. This adjustment is unnecessary for a pulse train + symbol and an A-phase/B-phase pulse train.
CAUTION
●
Even though the command pulse logic of the existing MR-J2S-_A_ servo amplifier
is not the same as its positioning module, the motor will rotate, but in the MR-J4-
_A_ servo amplifier, when the logics are not set correctly, the motor will not rotate
normally. Make sure to check the information below to set the logics. Even when
another company's controller is used, check the logic setting.
(1) For A-series positioning modules
Command pulse logic setting (Note 1)
Signal type
A-series positioning module
Basic parameter 1 setting
MR-J4-_A_ servo amplifier
[Pr. PA13] setting
Open-collector type
Positive logic
Positive logic (_ _ 0 _ h)
Differential line driver type
Positive logic (Note 2)
Negative logic (_ _ 1 _ h)
Note 1. When a pulse train + symbol and an A-phase/B-phase pulse train are used, it is unnecessary to adjust the logics.
2. For A-series and Q-series positioning modules, this logic points to the N-side waveform. Therefore, reverse the
command pulse logic of the servo amplifier.
(2) For Q-series positioning module
Command pulse logic setting (Note 1)
Signal type
Q-series positioning module
Pr. 23 setting
MR-J4-_A_ servo amplifier
[Pr. PA13] setting
Positive logic
Positive logic (_ _ 0 _ h)
Open-collector type
Negative logic
Negative logic (_ _ 1 _ h)
Positive logic (Note 2)
Negative logic (_ _ 1 _ h)
Differential line driver type
Negative logic (Note 2)
Positive logic (_ _ 0 _ h)
Note 1. When a pulse train + symbol and an A-phase/B-phase pulse train are used, it is unnecessary to adjust the logics.
2. For A-series and Q-series positioning modules, this logic points to the N-side waveform. Therefore, reverse the
command pulse logic of the servo amplifier.
(3) For F-Series positioning module
Command pulse logic setting
Signal type
F-series positioning module
