Stall protection (only for vector control)

If, for closed-loop speed control with encoder, the speed threshold set in p1744 for stall

detection is exceeded, then r1408.11 (speed adaptation, speed deviation) is set.

If the fault threshold value set in p1745 is exceeded when in the low speed range (less than

p1755 x (100% - p1756)), r1408.12 (motor stalled) is set.

If one of these two signals is set, then after the delay time in p2178, fault F07902 (motor

stalled) is returned.
