Basic Functions / Parameters; Rated Operational Current - Siemens SIRIUS M200D Manual

Self-protection
The motor protects itself against fatal damage by means of the thermal motor model and
temperature measurements for electronic switching elements. If the self-protection responds,
● the motor and the brake output are switched off immediately!
● the "switching element overload" signal is generated.
Switching on with "emergency start" is not possible.

Note
All current values (e.g. blocking current, current limit values) are percentages of the rated
operating current set on the device (e.g. I

Basic functions / parameters

Definition
Basic parameters are "central" parameters required by a range of device functions.
3.3.1

Rated operational current

Here, you can enter the rated operating current that the branch (switchgear and motor) can
carry without interruption. This is usually the rated motor current. The setting range depends
on the output class of the M200D motor starter (0.15 ... 2 A or 1.5 ... 12 A).
Note
The rated operating current is one of the key parameters.
The rated operating current must always be set if motor protection is to be ensured via the
electronic overload relay.
The overload relay can be deactivated.
In this case, motor protection must be ensured by means of a thermistor in the motor.
