STALL TRIP
The function block protects the motor from
damage that may be caused by continuous
operation beyond specification.
Functional Description
If STALL LIMIT TYPE is set to TORQUE and the estimated load exceeds the active TORQUE
LIMIT (refer to the TORQUE LIMIT function block) for a time greater than STALL TIME then
the stall trip will become active. The timer is reset whenever the estimated load is less than the
active Torque Limit.
Similarly, if the STALL LIMIT TYPE is set to CURRENT and the measured current exceeds the
active Current limit (i.e. the drive is in current limit) for a time greater than STALL TIME then
the stall trip will become active. The timer is reset whenever the measured current is less than the
active Current Limit.
Refer to the Installation Product Manual, Chapter 6 for a description of the trips supported by the
Inverter.
