3.5.3 Output signals
Refer to section 3.8.2 for the output interfaces (symbols in the I/O Division field in the table) of the
corresponding connector pins.

Encoder A-phase pulse
(differential line driver)
LA
LAR
CN6-11
CN6-24
Outputs pulses per servo motor revolution set in parameter No. PA15
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 parameter No. PC19.

CN6-13
CN6-26
Outputs the zero-point signal of the encoder in the differential line
driver system. One pulse is output per servo motor revolution. This
signal turns on when the zero-point position is reached. (Negative
logic)The minimum pulse width is about 400
s. For home position
return using this pulse, set the creep speed to 100r/min. or less.

power supply input
DICOM CN6-5
Used to input 24VDC (24VDC 10% 150mA) for I/O interface of the
servo amplifier. The power supply capacity changes depending on
the number of I/O interface points to be used. Connect the positive
terminal of the 24VDC external power supply for the sink interface.
