10.2 Fault and warning handling during operation
10.2.1 Classification of faults and warnings
Servo faults and warnings are divided into two categories: Category 1 (simply called Gr.1) and Category 2 (simply
called Gr.2)
Stopping method in case of failure.
Gr.1:
The stopping method in the event of a fault depends on Pn004. the factory setting is free stop.
Gr.2:
The method of stopping in the event of a fault depends on Pn005. the factory setting is zero speed stop with
zero speed command.
Is the fault resettable?
Yes:
can be de-activated by a fault reset.
No: the
fault cannot be lifted by a fault reset.
"Can be lifted by fault reset" means that the user can stop the panel fault display by "resetting the signal". Specific
operation method:
Method 1
: Press the "Up" + "Down" keys on the keyboard panel at the same time.
Method 2:
Fault reset release via auxiliary function Fn303
Method 3:
Use the di input terminal x to clear.
Associated fault clearing terminal function no.

Cautions
For some of the troubles that can be removed, the relevant settings must be changed to remove
the cause of the fault.
Only then can it be reset.
● For some non
-removable faults, it is necessary to reproduce the upper control power (l1c, l2c)
in order to clear it, at the upper power.
Before you can do this, or before you can enable it, you need to investigate the cause of the
relevant fault.
