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: Refer to: 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 de-activated.
Description: Displays the actual system deviation of the speed controller.
Description: Displays the slip frequency for induction motors (ASM).
Description: Display and connector output for the unsmoothed output frequency of the power unit.
Frequency components from the slip compensation (induction motor) are included.
Dependency: Refer to: r0024
Note: The output frequency is available smoothed (r0024) and unsmoothed (r0066).
