Siemens SINAMICS G120X - CO: Ramp-Function Generator Acceleration; RFG Acceleration; CO: Speed Controller Setpoint Sum; Speed Setpoint Sum; Fixed Speed Setpoint Number Actual; N_Set_Fixed no Act

Note
In the U/f mode, ramp-function generator tracking is not active.
The speed difference is reduced if the integral component of the speed controller is not maintained when the torque limit
is reached (p1400.16 = 1).
p1148[0...n] Ramp-function gen. tolerance for ramp-up and ramp-down active / RFG tol HL/RL act
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: 3_1 Unit selection: p0505 Function diagram: 3070
Min:
0.000 [rpm]
Max:
1000.000 [rpm]
Factory setting:
19.800 [rpm]
Description: Sets the tolerance value for the status of the ramp-function generator (ramp-up active, ramp-down active).
If the input of the ramp-function generator does not change in comparison to the output by more than the entered
tolerance time, then the status bits "ramp-up active" and "ramp-down active" are not influenced.

r1149 CO: Ramp-function generator acceleration / RFG acceleration
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: - Scaling: p2007 Dynamic index: -
Unit group: 39_1 Unit selection: p0505 Function diagram: 3070
Min:
- [rev/s²]
Max:
- [rev/s²]
Factory setting:
- [rev/s²]
Description: Displays the acceleration of the ramp-function generator.

r1170 CO: Speed controller setpoint sum / Speed setpoint sum
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: - Scaling: p2000 Dynamic index: -
Unit group: 3_1 Unit selection: p0505 Function diagram: 3001, 3080,
6300
Min:
- [rpm]
Max:
- [rpm]
Factory setting:
- [rpm]
Description: Display and connector output for the speed setpoint after selecting the ramp-function generator.
The value is the sum of speed setpoint 1 (p1155) and speed setpoint 2 (p1160).
r1197 Fixed speed setpoint number actual / n_set_fixed No act
Access level: 4 Calculated: - Data type: Unsigned32
Can be changed: - Scaling: - Dynamic index: -
Unit group: - Unit selection: - Function diagram: 3010
Min:
-
Max:
-
Factory setting:
-
Description: Displays the number of the selected fixed speed/velocity setpoint.
Dependency: See also: p1020, p1021, p1022, p1023
Note
If a fixed speed setpoint has not been selected (p1020 ... p1023 = 0, r1197 = 0), then r1024 = 0 (setpoint = 0).
