When a PROFINET alarm occurs, the Servomotor will stop according to the setting of
object Fault Reaction Option Code (605Eh). The default setting is to 2, i.e. to slow down
on quick stop ramp and turn the servo off. Refer to the following section for details.

6.14 Motor Overload Detection Level
6.14.1 Overview
The motor overload detection level is the threshold used to detect overload alarms and
overload warnings when the Servomotor is subjected to a continuous load that exceeds
the Servomotor ratings.
It is designed to prevent Servomotor overheating.
You can change the detection timing for A.910 warnings (Overload) and A.720 alarms
(Continuous Overload). You cannot change the detection level for A.710 alarms (Instanta-
neous Overload).
6.14.2 Detection Timing for Overload Warnings (A.910)
With the default setting for overload warnings, an overload warning is detected in 20% of
the time required to detect an overload alarm. You can change the time required to detect
an overload warning by changing the setting of the overload warning level (Pn52B). You
can increase safety by using overload warning detection as an overload protection func-
tion matched to the system.
The following graph shows an example of the detection of overload warnings when the
overload warning level (Pn52B) is changed from 20% to 50%. An overload warning is
detected in half of the time required to detect an overload alarm.
