6.8.6.1
Stall protection
Function description
If the load of a standard induction motor exceeds the stall torque of the motor, the motor can
also stall during operation on the converter. A stalled motor is stationary and does not develop
sufficient torque to accelerate the load.
If the "Motor model fault signal stall detection" r1746 for the time p2178 is present via the "Motor
model error threshold stall detection" p1745, the converter signals "Motor stalled" and fault
F07902.

6.8.6.2
No-load monitoring
Function description
An inadequate motor current indicates an interruption in the power transmission from the motor
to the load.
If the motor current for the time p2180 lies below the current level p2179, the converter signals
"output load not available" and alarm A07929.
