This parameter can be assigned to a programmable digital output.
The Overload control function allows an overcurrent for a limited time that can also exceed the rated current of
the inverter. It is used in order to provide the drive with an increased acceleration torque or for example to allow
peak loads, such as with cyclical loads characteristis.

Overload mode
Curr limited
The armature current is restricted to the limits set by the Over-
load control (size and duration of overcurrent).
Curr not limited
The armature current is not limited by the Overload con-
trol. However, an alarm is possible via the Overload state
parameter. This alarm indicates whether the current is within
the set limits or not.
I2t Motor
• If Motor I2t ovrld is set to Activity = Ignore,
the current is reduced from Overload current parameter value
to Base current parameter value when Motor I2t accum =
