Description
Overload limit is calculating by formula:
T = T * (I / I )
act set lim act
Where,
T = 79.91 Overload trip count down
act
T = 79.48 Overload delay time
set
I = 79.90 Overload actual limit
lim
I = 79.42 Overload supervision signal

T = T * (I / I )
act set lim act
Where,
T = 79.91 Overload trip count down
act
T = 79.48 Overload delay time
set
I = 79.90 Overload actual limit

Defines the time used as on-delay for the overload protection
function to react to the overload condition.
Overload delay in seconds.
Defines the response to the overload condition.
If the overload supervision signal is above active overload
limit in the defined delay time, then overload protection
function trigger the reaction defined in this parameter setting.
Overload event reaction is inactive.
Overload condition triggers the drive event
warning. It will stay on as long as overload condition is
present. The warning will automatically disappear if overload
supervision signal stays below the overload limit for the time
defined in parameter 79.48 Overload delay
Overload condition triggers the drive event
warning and immediate stop command. Drive will stop
according to parameter
Overload condition triggers the drive event
fault which immediately trips the drive.
In case recovery routine helps, the motor speed returns to
production speed. If not, drive generates the event
Overload warning. It will stay on as long as overload condition
is present. The warning will automatically disappear if
overload supervision signal stays below the overload limit for
the time defined in parameter
Overload condition triggers the overload recovery sequence.
In case recovery routine helps, motor speed returns to
production speed. If not, drive generates the event
Overload fault which immediately trips the drive.
