OP CN1-21 Outputs the zero-point signal of the encoder. One pulse is output per servo
motor revolution. OP and LG are connected 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.
LA CN1-15 Outputs pulses per servo motor revolution set in parameter No.27 in the
LAR CN1-16 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-
LB CN1-17
and B-phase pulses can be changed using parameter No.54.
LBR CN1-18
LZ CN1-19 The same signal as OP is output in the differential line driver system.
LZR CN1-20
MO1 CN3-4 Used to output the data set in parameter No.17 to across MO1-LG in terms
of voltage. Resolution 10 bits
MO2 CN3-6 Used to output the data set in parameter No.17 to across MO2-LG in terms
of voltage. Resolution 10 bits

VIN CN1-1 Used to input 24VDC for input interface.
Connect the positive terminal of the 24VDC external power supply.
24VDC 10
OPC CN1-2 When inputting a pulse train in the open collector system, supply this
terminal with the positive ( ) power of 24VDC.
SG CN1-13 Common terminal for output signals such as ALM and INP.
Separated from LG.
LG CN1-14 Common terminal for OP, MO1, and MO2.
Pins are connected internally.
SD Plate Connect the external conductor of the shield cable.
