pleted input signal turns ON after positioning has been completed.

3-5-4 Wiring Precautions
Operational errors such as dislocation can occur in most electronic control
devices if they are subjected to electronic noise from nearby power lines or
loads. Recovery from such errors is usually very difficult and time consuming.
To avoid such noise-generated operational errors and improve system reliabil-
ity, always observe the following precautions in wiring the system.
Be sure to use the sizes and materials indicated in the specifications when
connecting power lines and cables.
Power lines (e.g., AC power supply, motor power line) and control lines (e.g.,
pulse output lines, external I/O signal lines) must be wired separately. Never
put these lines into the same duct or make them into a single bundle.
• Attach a multi-layer ceramic capacitor of a thickness of less than 1
µ
F to
the pulse output power supply to improve noise resistance.
• Do not use a 24-V DC or 5-V DC power supply for pulse output in com-
mon with the power supply for other I/O.
• Use shielded cable for control lines.
• Connect the shielded cable to the frame ground at both the PCU and the
driver.
