tOL M Application Overload time delay 0 to 100 s 0 s
This function can be used to stop the motor in the event of an application overload. This is not a motor or
drive thermal overload. If the motor current exceeds the Application Overload threshold LOC, an
Application Overload time delay tOL is activated. Once this time delay tOL has elapsed, if the current
is still greater than the overload threshold LOC -10%, the drive will stop running and display OLC
Process overload.
Overload detection is only active when the system is in steady state (speed reference reached).
A value of 0 will disable application overload detection.
FtO
T
M Time delay before automatic start for the
overload fault 0 to 6 min 0 min
If Atr = YES the drive restarts automatically after an overload fault OLC once this time delay has elapsed.
Minimum time permitted between an overload being detected and any automatic restart.
In order for an automatic restart to be possible, the value of Maximum restart time tAr page 91 must
exceed that of this parameter by at least one minute.
Visible only if Application Overload time delay tOL above is not set to nO.
LOC
T
M Application Overload threshold 70 to 150% of nCr 90% of of nCr
Visible only if Application Overload time delay tOL above is not set to 0.
This parameter is used to detect an "application overload". LOC can be adjusted between 70 and 150%
of the nominal drive current. This is not a motor or drive thermal overload.
TParameter that can be modified during operation or when stopped.
