Description: Sets the speed threshold value to detect a stalled motor.
If the adaptation controller output exceeds the parameterized speed difference, then in status word r1408.11 is set =
1.
Dependency: If a stalled drive is detected (r1408.11 = 1), fault F07902 is output after the delay time set in p2178.
Refer to: p2178
Note: Speed monitoring is only effective in operation with a speed encoder (refer to p1300).
Stalling is also identified if steps/jumps occur in the speed signal, which exceed the value in p0492.
Description: Sets the fault threshold in order to detect a motor that has stalled.
If the error signal (r1746) exceeds the parameterized error threshold, then status signal r1408.12 is set to 1.
Dependency: If a stalled drive is detected (r1408.12 = 1), fault F07902 is output after the delay time set in p2178.
Refer to: p2178
Note: Monitoring is only effective in the low-speed range (below p1755 * (100% - p1756)).
Description: Signal to initiate stall detection
Note: The signal is not calculated while magnetizing and only in the low speed range (below p1755 * (100 % - p1756)).
Description: Sets the lower speed for the transition "n_set -> n_act" in encoderless operation.
This value is entered as a percentage referred to p1749.
Dependency: Refer to: p1749, p1752
