Error information in this area indicates errors that have occurred in individual
axes.
The Axis error code is indicated as 3
@@@
hex or 4
@@@
hex.
If an Axis Error Flag turns ON, error processing must be performed for the
corresponding axis.
Determine the cause of the error using the indicator display and error code,
isolating the location of the error as either in the PCU or in the Servo Drive/
Machine.
12-4-2 List of Error Codes
PCU Common Errors
The above errors for which the RUN indicator is not lit occur when starting
PCU operations, such as turning ON the power or restarting the Unit. The
PCU system does not start correctly if any of these errors occurs, so the Error
Flags and error codes cannot be checked from the CPU Unit.
