Description: Displays the currently smoothed speed setpoint at the input of the speed controller or U/f characteristic (after the
interpolator).
Dependency: Refer to: r0060
Note: Smoothing time constant = 100 ms
The signal is not suitable as a process quantity and may only be used as a display quantity.
The speed setpoint is available smoothed (r0020) and unsmoothed (r0060).
Description: Displays the smoothed actual value of the motor speed.
For U/f control and when slip compensation is deactivated (see p1335), the synchronous speed to the output
frequency is shown in r0021.
Dependency: Refer to: r0022, r0063
Note: Smoothing time constant = 100 ms
The signal is not suitable as a process quantity and may only be used as a display quantity.
The speed actual value is available smoothed (r0021, r0022) and unsmoothed (r0063).
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.
Description: Displays the smoothed actual value of the motor speed.
r0022 is identical to r0021, however, it always has units of rpm and contrary to r0021 cannot be changed over.
For U/f control and when slip compensation is deactivated (see p1335), the synchronous speed to the output
frequency is shown in r0022.
Dependency: Refer to: r0021, r0063
Note: Smoothing time constant = 100 ms
The signal is not suitable as a process quantity and may only be used as a display quantity.
The speed actual value is available smoothed (r0021, r0022) and unsmoothed (r0063).
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.
