Figure 9. Stall time count.
P10.4 STALL FREQUENCY LIMIT
Stall is recognized when the current limiter has reduced the output frequency below P10.4, for
the time in P10.3.
P10.5 U
NDERLOAD FAULT
0: No action
1: Warning
2: Fault
Underload is recognized when torque is above the minimum curve defined by P10.6 and P10.7,
for the programmed time P10.8.
P10.6
UNDERLOAD FAULT: FIELD WEAKENING AREA LOAD
The torque limit can be set between 10.0-150.0% x T
nMotor
.
This parameter gives the value for the minimum torque allowed when the output frequency is
above the field weakening point.
