Description:
Displays the effective flux setpoint.
The value is referred to the rated motor flux.
p1601[0...n]
Current injection ramp time / I_inject t_ramp
Access level: 3
Can be changed: T, U
Unit group: -
Min:
1 [ms]
Description:
Synchronous-reluctance motor:
Sets the ramp-up time of the current setpoint (p1610, p1611) when switching over from closed-loop controlled to open-
loop controlled operation.
p1610[0...n]
Torque setpoint static (sensorless) / M_set static
Access level: 2
Can be changed: T, U
Unit group: -
Min:
-200.0 [%]
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.
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.
p1611[0...n]
Additional acceleration torque (sensorless) / M_suppl_accel
Access level: 2
Can be changed: T, U
Unit group: -
Min:
0.0 [%]
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).
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).
