6.2.2
Parameterising of the motor and the current controller
In addition to the motor parameters (rated current, number of pole pairs), the
safety−relevant parameters (max. current, i
2
t tripping criterion) also have to be specified
in advance. The current controller parameters can be adapted as well.

Entry of the rated motor current
The rated motor current
(motor_rated_current) is entered in mA
(example: 5000 mA corresponds to
1388
h
)

Definition of the maximum current
To restrict the current (max_current) /
the maximum torque, the current is
limited to twice the rated motor current
(corresponds to 2000 / 07D0
h
).
