Troubleshooting
Computer Monitor Software
• Install and use the Computer Monitor Software. The following three items are required: A Windows
95/98-compatible computer, Computer Monitor Software, and R88A-CCW002P@ Connecting
Cable.
• Refer to the Computer Monitor Software for operation details.
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 measuring the encoder output, measure using the ground (CN1-16 pin) as standard. If mea-
suring using an oscilloscope, measure using the differential between CH1 and CH2 to reduce inter-
ference from noise.
• 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.
Checking Alarm Codes at the Controller
■
• The alarm codes that occur at the Servo Driver with regard to CS1W-MCH71 and CJ1W-MCH71
Motion Control Units and CJ1W-NCF71 Position Control Units are stored in the Controller as shown
below.
● Controller Alarm Codes
• Alarm codes such as the following are stored at the Controller for alarms that occur at the Servo
Driver.
Controller alarm (error) code: 40@@ (Hex)
The leftmost two digits from the Servo Driver's 3-digit alarm code are entered at the two boxes
( ).
@@
Example: Deviation counter overflow alarm at Servo-ON (A.d01).
The alarm code stored at the Controller is 40D0 (hex).
