Siemens SINAMICS G120XA - CO: Actual Speed; Actual Speed; CO: Speed Controller System Deviation; N_Ctrl Sys Dev; CO: Speed Setpoint after the Filter; N_Set after Filter; Slip Frequency; F_Slip

Note
The speed setpoint is available smoothed (r0020) and unsmoothed (r0060).
r0062 CO: Speed setpoint after the filter / n_set after filter
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: - Scaling: p2000 Dynamic index: -
Unit group: 3_1 Unit selection: p0505 Function diagram: 6020, 6030,
6031, 6822
Min:
- [rpm]
Max:
- [rpm]
Factory setting:
- [rpm]
Description: Display and connector output for the speed setpoint after the setpoint filters.
r0063[0...2] CO: Actual speed / Actual speed
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: - Scaling: p2000 Dynamic index: -
Unit group: 3_1 Unit selection: p0505 Function diagram: 6020, 6730,
6799, 6841
Min:
- [rpm]
Max:
- [rpm]
Factory setting:
- [rpm]
Description: Display and connector output for the speed actual value.
Frequency components from the slip compensation (for induction motors) are not included.
Index: [0] = Unsmoothed
[1] = Smoothed with p0045
[2] = Calculated from f_set - f_slip (unsmoothed)
Dependency: See also: r0021, r0022
Note
The speed actual value r0063[0] – smoothed with p0045 – is additionally displayed in r0063[1]. r0063[1] can be used
as process variable for the appropriate smoothing time constant p0045.
The speed (r0063[2]) calculated from the output frequency and slip can only be compared with the speed actual value
(r0063[0]) in the steady-state.
For U/f control, the mechanical speed calculated from the output frequency and the slip is shown in r0063[2] even if slip
compensation is deactivated.
r0064 CO: Speed controller system deviation / n_ctrl sys dev
Access level: 3 Calculated: - Data type: FloatingPoint32

Unit group: 3_1 Unit selection: p0505 Function diagram: 6040, 6824
Min:
- [rpm]
Max:
- [rpm]
Factory setting:
- [rpm]
Description: Displays the actual system deviation of the speed controller.
r0065 Slip frequency / f_Slip
Access level: 3 Calculated: - Data type: FloatingPoint32

Max:
- [Hz]
Factory setting:
- [Hz]
Description: Displays the slip frequency for induction motors (ASM).
