Troubleshooting Procedure
Section 12-2
Timing Chart for Axis Errors and Warnings
Note
If an axis warning occurs (Warning Flag = 1), the PCUs’ command response
time will be delayed due to the warning processing. The PCU processing time
required from receiving a command from the CPU Unit until the command is
sent using MECHATROLINK communications is one MECHATROLINK com-
munications cycle if an axis warning has not occurred, and three MECHA-
TROLINK communications cycles if an axis warning has occurred. If the
machine's operation is affected by the PCU's command response time, clear
the axis warning status using ERROR RESET or disable the warnings using
the Servo Drive settings.
For details on the PCU's command response time, refer to
Command
Response Time
in
Appendix A Performance Characteristics
.
12-2 Troubleshooting Procedure
The basic flow of troubleshooting errors that occur in the PCU is as follows:
ERROR RESET Bit
(word a, bit 12)
Warning Flag
(word b, bit 11)
Error Flag
(word b, bit 12)
Busy Flag
(word b, bit 13)
Axis error code
(word b+4)
0000
4096 (Hex)
0000
4096 (Hex) 40E6 (Hex)
(Example)

error
The Busy Flag remains ON for at
least one cycle time when ERROR
RESET is executed.
If the Error Flag turns ON while the
Warning Flag is already ON, the axis
error code will be overwritten.
a = Beginning word of Axis Operating Output Areas specified in Common Para (Axis No.
