Part 2: Review on Replacement of MR-J2S-_A_ with MR-J4-_A_
2 - 45
3.7 Important Points for Replacement (Command Pulse Logic Settings)
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 servo motor will rotate, but in the
MR-J4-_A_ servo amplifier, when the logics are not set correctly, the servo 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
Signal type
Command pulse logic setting (Note 1)
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 modules
Signal type
Command pulse logic setting (Note 1)
Q-series positioning module
[Pr. 23] setting
MR-J4-_A_ servo amplifier
[Pr. PA13] setting
Open-collector type
Positive logic
Positive logic (_ _ 0 _ h)
Negative logic
Negative logic (_ _ 1 _ h)
Differential line driver type
Positive logic (Note 2)
Negative logic (_ _ 1 _ h)
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 modules
Signal type
Command pulse logic setting
F-series positioning module
(fixed)
MR-J4-_A_ servo amplifier
[Pr. PA13] setting
Open-collector type
Negative logic
Negative logic (_ _ 1 _ h)
