LA CN3-6
Outputs pulses per servo motor revolution set in parameter No. PA15 in the
LAR CN3-16
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- and
LB CN3-7
B-phase pulses can be changed using parameter No. PC03.
LBR CN3-17
Output pulse specification and dividing ratio setting can be set. (Refer to
Section 5.1.9.)
LZ CN3-8
Outputs the zero-point signal in the differential line driver system of the
LZR CN3-18
encoder. One pulse is output per servo motor revolution. turns on when the
zero-point position is reached.
The minimum pulse width is about 400 s. For home position return using this
pulse, set the creep speed to 100r/min. or less.
MO1 CN3-4
Used to output the data set in parameter No. PC09 to across MO1-LG in terms
of voltage. Resolution 10 bits
MO2 CN3-14
Used to output the data set in parameter No. PC10 to across MO2-LG in terms
of voltage. Resolution 10 bits
Connector Pin
Symbol
No.
DICOM CN3-5
Used to input 24VDC (150mA) for input interface. The power supply capacity
CN3-10
changes depending on the number of I/O interface points to be used.
Connect the positive terminal of the 24VDC external power supply.
24VDC 10%
Pins are connected internally.
DOCOM CN1-46 Connect
CN1-47
Common terminal for input signals such as EM1. Pins are connected internally.
Separated from LG.
LG CN3-1 Common terminal of M01 M02
CN3-11 Pins are connected internally.
SD Plate
Connect the external conductor of the shield cable.
