Theoretically, the maximum torque must decrease at sufficient high current in the
d-axis according 1/x characteristic.

This means: ds11 torque mode Bit 0/1 field weak curve limit must be set to 0: 1/x.
A 1/x function is defined by specifying a single point which is passed through. This
point is determined by parameters dr13 and dr25.

dr13
breakdown torque %
Torque and speed for the definition of the limiting
characteristic
0x2219
dr25
breakdown speed %
dr25 defines the speed and dr13 defines the limit characteristic (max.) torque
which is appropriate to this speed.)
The torque value is entered in dr13 breakdown torque % in % of the motor rated
torque.
The speed value is entered in dr25 breakdown speed % in % of the rated field
weakening speed . This is calculated as follows:
