6.3.1

Basic functions/parameters during first commissioning

The default settings listed in the following two chapters apply to first commissioning and as
defaults for the programming devices (exception: rated operational current). When a motor
starter is set to the commissioning mode again, it uses the values that were valid when the
technology supply voltage was last lost.
6.3.2

Rated operational current

This parameter is used to set the rated operational current that the feeder can carry without
interruption. Usually, the rated operational current of the motor is specified on the rating plate
of the motor. The adjustment range depends on the performance class of the
ET 200SP motor starter.
Note
Rated operational current
The rated operational current is one of the key parameters.
You cannot disable motor protection completely. However, you can prevent the shutdown of
the motor by selecting the parameter Overload protection (Page 76).
In this case, motor protection must be ensured by other measures
(e.g. a thermistor in the motor).
Note
Functional switching
Observe the minimum loads for the ET 200SP motor starters.
The minimum loads are specified in the technical specifications of the relevant device. You
can find more information on the minimum loads in chapter "Minimum load current
(Page 72)".
