Setting The Command Pulse Logic - Mitsubishi Electric MELSERVO-J2S Series Manual

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
(1) For A-series positioning modules
Signal type
Open-collector type
Differential line driver type
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
Signal type
Open-collector type
Differential line driver type
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
Signal type
Open-collector type
● 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.
