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.
Description: Enters the dynamic torque setpoint for the low-speed range for sensorless vector control (SLVC). This parameter is
entered as a percentage referred to the rated motor torque (r0333).
Note: When accelerating and braking p1611 is added to p1610 and the resulting total torque is converted into an appro-
priate current setpoint and controlled.
For pure accelerating torques, it is always favorable to use the torque pre-control of the speed controller (p1496).
Description: Displays the actual maximum possible electromotive force (EMF) of the separately-excited synchronous motor.
Dependency: The value is the basis for the flux setpoint.
The maximum possible EMF depends on the following factors:
- Actual DC link voltage (r0070).
- Maximum modulation depth (p1803).
- Field-generating and torque-generating current setpoint.
