P3.9.3.1 MOTOR STALL FAULT (ID 709)
Use this parameter to select the response of the drive to a 'Motor Stall' fault.
If the stall protection detects that the shaft of the motor is stalled, a motor stall fault occurs.
P3.9.3.2 STALL CURRENT (ID 710)
Use this parameter to set the limit above which the current of the motor must stay for a stall
stage to occur.
If the value of the motor current limit parameter changes, this parameter is automatically
set to 90 % of the current limit.
You can set the value of this parameter between 0.0 and 2*IL. For a stall status to occur, the
current must be higher than this limit. If parameter P3.1.3.1 Motor Current Limit changes,
this parameter is automatically calculated to 90% of the current limit.
NOTE!
The value of the Stall Current must be below the motor current limit.

P3.9.3.3 STALL TIME LIMIT (ID 711)
Use this parameter to set the maximum time for a stall stage.
This is the maximum time for the stall stage to be active before a motor stall fault occurs.
You can set the value of this parameter between 1.0 and 120.0 s. An internal counter counts
the stall time.
If the stall time counter value goes above this limit, the protection causes the drive to trip.
P3.9.3.4 STALL FREQUENCY LIMIT (ID 712)
Use this parameter to set the limit below which the output frequency of the drive must stay
for a stall stage to occur.
