Note: PMSM: permanent-magnet synchronous motor
For bit 17:
Displays the enabled status of the rugged model feedback (p1784).
The feedback is used to increase the parameter ruggedness of the motor model and is effective in the operating
range of the two-component closed loop current control.
For bit 18:
Displays the status when enabling the differential current feedback in the current model for operation with encoder.
The function is automatically enabled with p1784 > 0 or p1731 > 0.
The feedback is used for a rugged change between the current model and complete machine model with active
rugged model feedback and combination current.
For bit 19:
Displays the currently active stator circuit feedback in current model operation.
For bit 20:
Displays the currently effective increase of the changeover limits by the value p1749 * p1755.
For bit 21:
For a blocked synchronous motor, the speed ramp-function generator is held in the open-loop speed controlled
operating range if the torque setpoint reaches the torque limit and the speed is less than the threshold value in
p2175.

Description: Sets the speed to change over the motor model for operation with encoder.
Dependency: In U/f characteristic mode the parameter is of no significance.
Using the friction characteristic for operation with encoder:
When changing the motor model changeover speed p1752, the points along the friction characteristic should be
recalculated (p0340 = 5) and the friction characteristic recorded again (p3845). For slight changes, only the
associated friction characteristic points must be recorded (see p3844).
