CO: Outp. field weak. controller
Min: -
Datatype: Float Unit:
%
Def:
-
P-Group: CONTROL
Max: -
Displays output signal of field weakening controller in [%] relative to rated motor flux.
r1598
CO: Flux setpoint (total)
Min: -
Datatype: Float Unit:

P1610[3]
Continuous torque boost (SLVC)
Min: 0.0
CStat:
CUT
Datatype: Float Unit:
%
Def:
50.0
P-Group: CONTROL
Active: Immediately
QuickComm.: No
Max: 200.0
Sets the constant torque boost for the low frequency range when sensorless closed-loop vector control is
being used (SLVC). The parameter is entered as a % referred to the rated motor torque (r0333).
For sensorless closed-loop vector control, when the motor model is disabled, an absolute current is
impressed. P1610 represents the maximum load that occurs at a constant setpoint.

Index:
P1610[0] : 1st. Drive data set (DDS)
P1610[1] : 2nd. Drive data set (DDS)
P1610[2] : 3rd. Drive data set (DDS)
Caution:
P1610 should always be set at least 10% higher than the maximum steady-state load that occurs.
Note:
-
For P1610 = 0 %, a current setpoint is calculated that corresponds to the no-load case (rated
magnetization current).
-
For P1610 = 100 %, a current setpoint is calculated that corresponds to the rated motor torque.
