As LA , LAR , LB and LBR , the pulses per servo motor revolution set
in the DRU parameter No. 38 of the corresponding slots are output in the
differential line driver system.
In CCW rotation of the servo motor, the encoder B-phase pulse lags the
encoder A-phase pulse by a phase angle of /2.
The relationships between rotation direction and phase difference of the A-
and B-phase pulses can be changed using DRU parameter No. 33.
As LZ and LZR the zero-point signals of the encoders of the
corresponding slots are output. One pulse is output per servo motor
revolution. The same signals as OP
in the DRU parameter No. 38 of the corresponding slots are output in the
differential line driver system.
In CCW rotation of the servo motor, the encoder B-phase pulse lags the
