Error Reset
Section 12-6
12-6 Error Reset
The PCU indicates Unit common errors and individual axis errors in the Com-
mon Operating Memory Area and Axis Operating Input Memory Areas,
respectively, using Error Flags and error codes.
These errors can be cleared by removing the cause of the error and executing
ERROR RESET.
The methods for resetting Unit common errors and individual axis errors are
different.
12-6-1 Resetting Unit Common Errors
Unit common errors are cleared by turning ON (
) the UNIT ERROR RESET
Bit in the Common Operating Memory Area.
Reset Unit common errors when the Unit Busy Flag for the Position Control
Unit is OFF. If errors are reset when the Unit Busy Flag is ON, a multistart
error (Unit error code: 0021) will occur and it will not be possible to reset Unit
common errors.
When clearing Unit common errors, make sure that the UNIT ERROR RESET
Bit in the Common Operating Memory Area remains ON until the Unit Busy
Flag turns ON.
Common Operating Memory Area (Output)
n = CIO 1500 + (unit number
×

Common Operating Memory Area (Input)
n = CIO 1500 + (unit number
