p1740[0...n] Gain resonance damping for encoderless closed-loop control / Gain res_damp
Access level: 3
Can be changed: U, T
Units group: -
Min
0.000
Description: Defines the gain of the controller for resonance damping for operation with sensorless vector control in the range
that current is injected.
p1744[0...n] Motor model speed threshold stall detection / MotMod n_thr stall
Access level: 4
Can be changed: U, T
Units group: 3_1
Min
0.00 [rpm]
Description: Sets the speed threshold value to detect a stalled motor.
If the adaptation controller output exceeds the parameterized speed difference, then bit 11 in status word p1408 is
set.
Dependency: If a stalled drive is detected (p1408.11 set), fault 7902 is output after the delay time 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.
p1745[0...n] Motor model error threshold stall detection / MotMod ThreshStall
Access level: 3
Can be changed: U, T
Units group: -
Min
0.0 [%]
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)).
r1746 Motor model error signal stall detection / MotMod sig stall
Access level: 3
Can be changed: -
Units group: -
Min
- [%]
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)).
