1. Error Messages
[Format]
Error No. : [<location where error occurred>,] error message
… Displays the error message on screen.
Code
: … Displays the error code in hexadecimal numbers.
Meaning/Cause
: … Displays the meaning and cause of the error.
Action : … Displays a message explaining action needed to eliminate
or avoid error status.
Dedicated output : … Refer to “(2) Dedicated output status”.
* The beginning of the error message may sometimes include information on the
location (axis, option unit, etc.) where the error occurred. An "M" in this
information indicates the main group axis No., an "S" indicates the sub group axis
No., a "D" indicates the driver axis No., and an "OP" indicates the option unit slot
No.
For example, a message "2.1:M1, Soft limit over" indicates that the preset soft limit
values have been exceeded on axis 1 of the main group robot. Likewise, the
message, "17.4:D2, Overload" indicates that an overload has occurred in axis 2 of
the driver unit. The axes viewed by the robot and the axes viewed by the driver are
normally a one-to-one match with each other, but when dual-drive axes are used,
one axis viewed by the robot may sometimes be treated as 2 axes by the driver.
