6.2.3.3 Application-specific data
Magnetising current in % of the rated motor current
Max. torque in % rated torque
Max. current in % rated motor current
Definition of the limiting characteristic by 1 point
(torque at speed) on the 1/x curve
DC reference voltage in V
Maximum current in the d-axis based on the maxi-
mum current (dr12).
For a synchronous motor dr08 should always be set to "off" (=> Chapter 6.2.5 Mag-
netizing current).
Manual setting of a magnetising current
The torque can be limited with dr11 in order to protect the mechanics against ex-
cessive torques.
This parameter is used together with dr12 to define the saturation characteristic, if
the influence of saturation should be considered (=> Chapter 6.2.13 Saturation
characteristic (SM)).
