Function and application
Digital I/F
Power supply input DICOM CN3-23 Input 24 V DC (24 V DC ± 10% 250 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 the 24 V DC external power supply.
Digital I/F
Common DOCOM CN3-26 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 the 24 V DC external power supply.
Control common LG CN3-1
CN3-14
This is for encoder output pulses (differential line driver).
Shield SD Plate Connect the external conductor of the shielded wire.
