15.1.3 Clearing Errors/Warnings Using User Programs
Errors and warnings can be cleared by turning on the "error clear request" or "warning clear
request" allocated to the output control area using user programs.
Clearing errors/warnings using unit memories (output control area)
It is possible to clear errors and warnings on an axis-by-axis basis by turning on the
error/warning clear request flags allocated to the output control area. Some errors cannot be
cleared. Some system errors and communication errors of AMP cannot be cleared by this
operation. The power supply of the unit should be restored.
(Example) When clearing the error in the axis no.1 of FP7 MC Unit installed in slot 1
