s When a Pr
oblem Occurs
The following figure shows the 7-segment display when an error exists.
Numbers from 0 to F hex are displayed as follows.
When you check and verify I/O after a problem 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 con-
nected, test results may not be accurate due to conduction via bypassing circuit.
• If the encoder signal is lost, the Servomotor may run away, or an error may occur. Be sure to discon-
nect the Servomotor from mechanical systems before you check the encoder signal.
• When you perform 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 Servomotor runs away.
Before you perform the tests, verify that you can immediately stop the machine by the use of func-
tions such as the immediate stop in case the machine runs out of control.
