11-1 Introduction
The errors detected by the Position Control Unit can be divided broadly into the
following categories.
The following checks are performed when the Unit is turned on or restarted.
•
Hardware check
•
Common parameters check
•
Flash memory check
•
Axis parameters check
The error status is retained when an error occurs. Refer to the tables for the
error-clearing procedure and clear the error.
When two or more errors have occurred, the next error will be detected when the
first error is cleared. Repeat the error-clearing procedure until all of the errors
have been cleared. When an error hasn’t been cleared, all commands will be
invalid except for the all-axis data transfer and data save operations.
An error check is performed when a command is executed or a data irregularity
is detected during operation. An error check is also performed when a software
limit, emergency stop, or limit signal is detected.
Refer to the tables in
11-4 Error Code Lists
for details on the Unit operation when
an error has occurred. If an emergency stop or limit signal error is detected when
an error has occurred, an emergency stop or limit signal error will be output.
Refer to the tables for the error-clearing procedure and clear the error.
Note
A command such as START can be performed after removing the cause of the
command execution error. Errors occurring during data transfers from the SYS-
MAC-NCT Support Tool or by the IORD/IOWR instructions can be cleared only
when the transfer was completed normally.
