p1611[0...n] Supplementary accelerating torque (SLVC) / M_suppl_accel
Access level: 2
Can be changed: U, T
Units group: -
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
Access level: 4
Can be changed: U, T
Units group: -
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 injected for sensorless vector control.
r1623[0...1] Field-generating current setpoint (steady-state) / Id_set stationary
Access level: 4
Can be changed: -
Units group: 6_2
Min
- [Arms]
Description: Displays the steady-state field generating current setpoint (Id_set).
Note: Re index 1:
Displays the stationary field-generating current on the stator side in the case of separately excited synchronous
motors without the excitation current monitoring component (r1644).
r1624 Field-generating current setpoint, total / Id_setp total
Access level: 4
Can be changed: -
Units group: 6_2
Min
- [Arms]
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.
r1650 Current setpoint torque-generating before filter / Iq_set before filt
Access level: 4
Can be changed: -
Units group: 6_2
Min
- [Arms]
Description: Displays the torque generating current setpoint Iqset after the torque limits and the clock cycle interpolation is
ahead of the current setpoint filters.
