p1416[0...n] Speed setpoint filter 1 time constant / n_set_filt 1 T
Access level: 4 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: 6020, 6030
Min:
0.00 [ms]
Max:
5000.00 [ms]
Factory setting:
0.00 [ms]
Description: Sets the time constant for the speed setpoint filter 1 (PT1).
r1438 CO: Speed controller speed setpoint / n_ctrl n_set
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: - Scaling: p2000 Dynamic index: -
Unit group: 3_1 Unit selection: p0505 Function diagram: 3001, 6020,
6031
Min:
- [rpm]
Max:
- [rpm]
Factory setting:
- [rpm]
Description: Display and connector output of the speed setpoint after setpoint limiting for the P component of the speed controller.
For U/f operation, the value that is displayed is of no relevance.
Note
In the standard state (the reference model is deactivated), r1438 = r1439.
r1445 CO: Actual speed smoothed / n_act smooth
Access level: 4 Calculated: - Data type: FloatingPoint32
Can be changed: - Scaling: p2000 Dynamic index: -
Unit group: 3_1 Unit selection: p0505 Function diagram: 6040
Min:
- [rpm]
Max:
- [rpm]
Factory setting:
- [rpm]
Description: Display and connector output for the actual smoothed speed actual value of the speed control.
p1452[0...n] Speed controller speed actual value smoothing time (sensorless) / n_C n_act T_s SL
Access level: 2 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: 6020, 6040
Min:
0.00 [ms]
Max:
32000.00 [ms]
Factory setting:
10.00 [ms]
Description: Sets the smoothing time for the actual speed of the speed controller for encoderless closed-loop speed control.
Note
The smoothing must be increased if there is gear backlash. For longer smoothing times, the integral time of the speed
controller must also be increased (e.g. using p0340 = 4).
