p1616[0...n] Current setpoint smoothing time / I_set T_smooth
Access level: 3 Calculated: CALC_MOD_REG Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: 6721, 6722
Min:
4 [ms]
Max:
10000 [ms]
Factory setting:
40 [ms]
Description: Sets the smoothing time for the current setpoint.
The current setpoint is generated from p1610 and p1611.
Note
This parameter is only effective in the range where current is injected for sensorless vector control.
p1740[0...n] Gain resonance damping for encoderless closed-loop control / Gain res_damp
Access level: 3 Calculated: CALC_MOD_CON Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: -
Min:
0.000
Max:
10.000
Factory setting:
0.025
Description: Defines the gain of the controller for resonance damping for operation with sensorless vector control in the range that
current is injected.
p1745[0...n] Motor model error threshold stall detection / MotMod ThreshStall
Access level: 3 Calculated: CALC_MOD_REG Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: -
Min:
0.0 [%]
Max:
1000.0 [%]
Factory setting:
5.0 [%]
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.
See also: 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 Calculated: - Data type: FloatingPoint32
Can be changed: - Scaling: - Dynamic index: -
Unit group: - Unit selection: - Function diagram: -
Min:
- [%]
Max:
- [%]
Factory setting:
- [%]
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)).
