P1611[3]
Acc. torque boost (SLVC)
Min: 0.0
CStat:
CUT
Datatype: Float Unit:
%
Def:
0.0
P-Group: CONTROL
Active: Immediately
QuickComm.: No
Max: 200.0
Enters the dynamic torque boost for the low frequency range for sensorless closed-loop vector control
(SLVC). The parameter is entered as a % referred to the rated motor torque (r0333).
Index:
P1611[0] : 1st. Drive data set (DDS)
P1611[1] : 2nd. Drive data set (DDS)
P1611[2] : 3rd. Drive data set (DDS)
Note:
-
When accelerating and braking, P1611 is added to P1610 and the resulting total torque is converted
into an appropriate current setpoint and controlled (closed-loop).
-
For pure accelerating torques, it is always more favorable to utilize the torque pre-control of the speed
controller (P1496).
