Precautions When A Problem Occurs; Replacing The Servo Drive - Omron R88D-KN series User Manual

12-1-2 Precautions When a Problem Occurs

When checking and verifying I/O after a problem has occurred, the Servo Drive may suddenly start to
operate or suddenly stop. Always take the following precautions.
You should assume that anything not described in this manual is not possible with this product.
Precautions
• Disconnect the wiring before checking for cable breakage. If you test conduction with the cable
connected, test results may not be accurate due to conduction via bypassing circuit.
• If the encoder signal is lost, the motor may run away, or an error may occur. Be sure to disconnect
the loading equipment before checking the encoder signal.
• When measuring the encoder output, perform the measurement based on the GND (CN1 pin 16).
• When performing tests, first check that there are no persons in the vicinity of the equipment, and that
the equipment will not be damaged even if the motor runs away. Before performing the tests, verify
that you can immediately stop the machine using an immediate stop in case the machine runs out of
control.
