8.4Stall protection (only for vector control)

Description

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, in the low speed range (less than p1755 * p1756), the fault threshold value, set in p1745 is exceeded, then r1408.12 is set (motor stalled).

If one of the two signals is set, then after the delay time in p2178, fault F7902 (motor stalled) is output.
