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 assume that anything not described in this manual is not possible with this product.
• 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 alarm may occur. Be sure to disconnect
the motor from mechanical systems before checking the encoder signal.
• When measuring the encoder output, perform the measurement based on the SGGND (CN1 pin 13).
When an oscilloscope is used for measurement, it will not be affected by noise if measurements are
performed using the differential between CH1 and CH2.
• 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.
