Blocked Rotor Detection (Menu Index 5.2.6)

6.6.3.4
Use the blocked rotor detection function to detect if the rotor is blocked by the application. This feature can protect the motor or
application and identify if something is preventing the drive from ramping up the motor to the desired speed reference. If the motor
is running in either torque or current limit for the set detection time, the blocked rotor function triggers an event. The function only is
active in the speed range from 0 up to the set blocked rotor maximum speed.
