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, so always take the following precautions.
You should assure that anything not described in this manual is not possible with this product.
Precautions
Disconnect the wire before checking for cable breakage. Even 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 motor from the mechanical system before checking the encoder signal.
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 emergency
stop even if it runs away.
