11. ERROR CODES STORED AT THE PCPU
Errors detected at the PCPU include servo program setting errors, positioning
errors, and control mode switching errors.
(1) Servo program setting errors
Servo program setting errors consist of errors in the positioning data
designated at the servo program. A check occurs for these errors each time a
servo program is started. When positioning data is designated indirectly, an
error will occur if the designated data violates the prescribed range.
When an error is activated, the following occur:
• The servo program setting error flag (M9079) switches ON.
• The error occurrence program is recorded in the error program No. storage
register (D9189).
• The error code is recorded in the error information storage register (D9190).
(2) Positioning errors
(a) Positioning errors occur at positioning START, or during the positioning
operation. There are three types of positioning error: minor errors, major
errors, and servo errors.
1) Minor error......... These errors are caused by the sequence program or
servo program. The error code range for these errors is
1 to 999 for drive modules, and 4000 to 9990 for output
modules. The cause of these errors can be eliminated
by correcting the sequence program or servo program
in accordance with the error code.
2) Major errors ...... These errors are caused by external input signals or by
control commands from the SCPU. The error code
range for these errors is 1000 to 1999 for drive
modules, and 10000 to 11990 for output modules.
Eliminate the cause of these errors in accordance with
the error code.
3) Servo errors...... These are errors detected by the servo amplifier or
servo power supply module. The error code range for
these errors is 2000 to 2999. Eliminate the cause of
these errors in accordance with the error code.
