(2) High reliability
a) The built-in microcomputer continuously checks the I/O data and the manipu-
lator motion to ensure high-reliability.
b) Can detect power supply faults and software faults with its self-diagnosis func-
tions.
(3) When an error such as an operation error or a controller fault occurs, the alarm code
and message are displayed, and the date and time of the error occurrence with its
explanation are stored in the alarm history to help you take a quick, corrective
action.
Be sure to save the backup data for the controller, such as the data for jobs and con-
stants, on a PC card. If not, the necessary data for the manipulator may be lost if an inter-
nal memory fault occurs in the controller.
