Wiring Section 2-3
The circuit in the table below is used to interface phase inputs A, A, B, B, Z,
and Z (for X to U) and MPG-A, MPG-A, MPG-B, and MPG-B.
The circuit in the table below is used to interface outputs OUT (X to U).
2-3-8 Wiring Precautions
Heed the following precautions when wiring the MC Unit to the servo drivers
and motors.
Electronically controlled equipment may malfunction because of noise gener-
ated by power supply lines or external loads. Such malfunctions are difficult to
reproduce; hence, determining the cause often requires a great deal of time.
The following tips should aid in avoiding noise malfunction and improving sys-
tem reliability.
Use electrical wires or cables of 0.2 mm
2
or as specified in the instruction
manual for the servo driver.
Use larger size cables for the FG lines of the PLC or the driver and ground
them over the shortest possible distance.
Separate power cables (AC power supply lines and motor power supply lines)
from control cables (pulse output lines and external input signal lines). Do not
group the two types of cable together or place them in the same conduit. Use
shielded cables for control lines.
