Description:
Sets the static torque setpoint for sensorless vector control in the low speed range.
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
represents the maximum load that occurs at a constant setpoint speed.
Dependency:
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
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
current, RESM: no-load magnetizing current).
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 as well as closed-loop controlled reluctance motors.
Description:
Enters the dynamic torque setpoint for the low-speed range for sensorless vector control.
This parameter is entered as a percentage referred to the rated motor torque (r0333).
Dependency:
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Note:
When accelerating and braking p1611 is added to p1610 and the resulting total torque is converted into an
appropriate current setpoint and controlled.
For pure accelerating torques, it is always favorable to use the torque precontrol 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.
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
