OLW
When reaching the overload setting, this DO is ON.
t
OL
= Overload allowable time of the servo x Setting
value of P1-56, when the overload accumulative
time exceeds
t
OL,
it will output pre-overload warning
(OLW). However, if the overload accumulative time
exceeds the overload allowable time of the servo, it
will output pre-overload error (ALRM).
For example:
The setting value of pre-overload warning is 60%
(P1-56=60).
When the output average load of the servo drive is
200%, if the output time exceeds 8 seconds, the servo
drive will show the overload alarm (AL.006).
t
OL
= The output average load of the servo exceeds
200% for 8 seconds x parameter setting value =
8sec x 60% = 4.8sec
Result: When the output average load of the servo
drive exceeds 200% for 4.8 seconds, this DO is ON. If it
exceeds for 8 seconds, then, DO.ALRM is ON.
