Troubleshooting
Computer Monitor Software
• Install and use the SMARTSTEP A-series Servo Driver Computer Monitor Software for Win-
dows version 2.0 (WMON Win Ver. 2.0) (Cat. No.: SBCE-011). The following three items are
required: A Windows-compatible computer, the Computer Monitor Software, and a Connecting
Cable (R7A-CCA002P@).
• Refer to the SMARTSTEP A-series Servo Driver Computer Monitor Software for operation de-
tails.
5-1-2 Precautions
When checking and verifying I/O after trouble has occurred, the Servo Driver may
suddenly start to operate or suddenly stop, so take precautions. Also, do not attempt
operations not specified in this manual.
■ Precautions
• Disconnect any cables before checking if they have burned out. Even if you have checked the con-
duction of the wiring, there is a risk of conduction due to the return circuit.
• If the encoder signal is lost, the Servomotor may run away, or an error may be generated. Make
sure the Servomotor is disconnected from the mechanical system before checking the encoder sig-
nal.
• When performing tests, first check that there are no personnel inside the machine facilities, and that
the facilities will not be damaged even if the Servomotor runs away. Also, check that even if the Ser-
vomotor runs away, you can immediately stop the machine using an emergency stop before per-
forming the tests.
