Description: Sets the integral-action time of the field-weakening controller.
Description: Displays the output of the field weakening controller.
The value is referred to the rated motor flux.
Description: Displays the effective flux setpoint.
The value is referred to the rated motor flux.
Description: Sets the static torque setpoint for sensorless vector control (SLVC).
This parameter is entered as a percentage referred to the rated motor torque (r0333).
For sensorless vector control, when the motor model is shut down, an absolute current is impressed. p1610 repre-
sents the maximum load that occurs at a constant setpoint speed.
Notice: p1610 should always be set to at least 10 % higher than the maximum steady-state load that can occur.
Note: For p1610 = 0%, a current setpoint is calculated that corresponds to the no-load case (ASM: rated magnetizing cur-
rent).
For p1610 = 100 %, a current setpoint is calculated that corresponds to the rated motor torque.
Negative values are converted into positive setpoints in the case of induction and permanent-magnet synchronous
motors.
