Heed the following precautions when wiring the MC Unit to the servo drivers

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 designated sizes as specified in the in-

struction manual for the servo driver.

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.

Using the laminated ceramic capacitor of 1 µ F for the output of 24 VDC

power supply will improve noise-resistance.

Use shielded cables for control lines.

For inductive loads such as relays or solenoid valves, connect surge ab-
