Basic functions / parameters
Definition
Basic parameters are "central" parameters required by a range of device functions.
3.3.1
Rated operating 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.
Current motor current
The latest current in the motor starter is returned via the process image for analysis.
The current is measured in all 3 phases and the highest value is calculated. The returned 6-
bit value specifies the motor current ratio I
curr
/ I
rated
(I
rated
= parameterized rated operating
current).
The value is represented by one digit before the decimal point (DI 1.5) and five digits after
the point (DI 1.0 to DI 1.4). This results in a maximum ratio for I
curr
/ I
rated
of 1.96875
(approx.197%).
The resolution is 1/32 per bit (3.125%).
