Parameter list
p1611[0...n] Supplementary accelerating torque (SLVC) / M_suppl_accel
VECTOR (n/M) Can be changed: U, T
Data type: Floating Point
P-Group: Control
Min
0.0 [%]
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).
p1616[0...n] Current setpoint smoothing time / I_set T_smooth
VECTOR (n/M) Can be changed: U, T
Data type: Floating Point
P-Group: Control
Min
4 [ms]
Description: Sets the smoothing time for the current setpoint.
The current setpoint is generated from p1610 and p1611.
Note: This parameter is only effective in the range where current is impressed for sensorless vector control.
r1623 Field-generating current setpoint (steady-state) / Id_set stationary
VECTOR (n/M) Can be changed: -
Data type: Floating Point
P-Group: Displays, signals
Min
- [Aeff]
Description: Displays the steady-state field generating current setpoint (Id_set).
r1624 Field-generating current setpoint, total / Id_set total
VECTOR (n/M) Can be changed: -
Data type: Floating Point
P-Group: Displays, signals
Min
- [Aeff]
Description: Displays the limited field-generating current setpoint (Id_set).
This value comprises the steady-state field-generating current setpoint r1623 and a dynamic component that is only
set when changes are made to the flux setpoint.
p1654[0...n] Current setpoint torque-generating smoothing time / Isq_set T_smooth
VECTOR (n/M) Can be changed: U, T
Data type: Floating Point
P-Group: Control
Min
0.1 [ms]
Description: Sets the smoothing time constant for the setpoint of the torque-generating current components.
Note: The smoothing time does not become effective until the field-weakening range is reached.
