2 Parameters
2.2 List of parameters
Negative values are converted into positive setpoints in the case of induction and permanent-magnet synchronous
motors.
p1611[0...n]

Additional acceleration torque (sensorless) / M_suppl_accel

VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: REL
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 pre-control of the speed controller (p1496).
p1612[0...n]

Current setpoint magnetizing open-loop controlled / Id_set ctrl

VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: ASM, PEM, REL
Min
0.00 [Arms]
Description: Sets the magnetizing current setpoint in the open-loop controlled encoderless operation.
The value is only valid during the current model orientation.
Dependency: Refer to: p1610, p1611
Note: The value is effective at speeds less than p1755 and represents a reserve for a possibly existing load torque or
torque error in the moment of inertia.

EMF maximum / EMF max

VECTOR_G (n/M) Can be changed: -
Data type: FloatingPoint32
P-Group: Displays, signals
Not for motor type: ASM, PEM, REL
Min
- [Vrms]
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.
p1616[0...n]

Current setpoint smoothing time / I_set T_smooth

VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: REL
Min
4 [ms]
Description: Sets the smoothing time for the current/torque setpoint in the open-loop-controlled operating range in the case of
sensorless vector control.
