These devices output pulses of encoder output pulse set in [Pr. PA15] in
the differential line driver type.
In CCW rotation of the servo motor, the encoder B-phase pulse lags the
encoder A-phase pulse by a phase angle of
ʌ /2.
The relation between rotation direction and phase difference of the A-
phase and B-phase pulses can be changed with [Pr. PC19].
Encoder Z-
phase pulse
(differential line
driver) LZ
LZR
CN1-8
CN1-9 The encoder zero-point signal is outputted in the differential line driver
type. One pulse is outputted per servo motor revolution. This turns on
when the zero-point position is reached. (negative logic)
The minimum pulse width is about 400
ȝ s. For home position return using
this pulse, set the creep speed to 100 r/min. or less.
DO-2
Encoder Z-
phase pulse
(open-collector) OP CN1-33 The encoder zero-point signal is outputted in the open-collector type. DO-2
Analog monitor 1 MO1 CN1-26 This is used to output the data set in [Pr. PC14] to between MO1 and LG in
terms of voltage.
Resolution: 10 bits or equivalent

supply input DICOM CN1-20
CN1-21
Input 24 V DC (24 V DC ± 10% 300 mA) for I/O interface. The power
supply capacity changes depending on the number of I/O interface points
to be used.
For sink interface, c of 24 V DC external power supply.
For source interface, connect - of 24 V DC external power supply.

input OPC CN1-12 When inputting a pulse train in the open-collector type with sink interface,
supply this terminal with the positive (+) power of 24 V DC.
Digital I/F
common DOCOM CN1-46
CN1-47
Common terminal of input signal such as EM2 of the servo amplifier. This
is separated from LG.
For sink interface, connect - of 24 V DC external power supply.
For source interface, c of 24 V DC external power supply.
Control common LG CN1-3
CN1-28
CN1-30
CN1-34
This is a common terminal for TLA, TC, VC, VLA, OP, MO1, and MO2.
Pins are connected internally.
