9.14 Advanced Position Control (including Active Vibration Suppression)

Using APC in conjunction with One Button Tuning (OBT)

When using APC in conjunction with One Button Tuning function (OBT), the APC function must

first be deactivated.

It is only permissible that the APC function is executed after OBT has been applied.

Proceed as follows to deactivate the APC function:

1. In parameter p3700.0, set the value to "0".

2. In parameter p3754, set the value to "0".

Using the APC filter

The APC filters serve to stabilize the control.

SINUMERIK applications

For SINUMERIK, in HMI Operate screen form-based support is provided using menu

"Commissioning > Optimization/test > Active filter > Filter group".

STARTER commissioning tool

In the STARTER commissioning tool (from version 5.1.1), via the navigation path "Drive_x >

Technology > Active oscillation damping > Filter setting", you can parameterize the appropriate

filter in the "Filter setting" screen form. For older versions, you must use the expert list to make

the settings.

● For each filter you can individually select as to whether it should be a general 2nd order filter

- or a lowpass (PT2) filter (p3705).

● The transfer function can be found in Chapter "Current setpoint filter" under the sub-heading

"Transfer function: General 2nd order filter". The structure of the APC filter is identical to that

of current setpoint filters.

● The parameters required to assign the filter parameters are shown in the function block

diagram 7012.

● The filter subsampling is helpful for low filter frequencies (p3706 or p3707). Check the filter

effect by analyzing the frequency response.

Observe the phase rotation as a result of filtering. The phase rotation may mean that there is

not enough phase reserve for the APC control loop.

Dependency on the parameter set

Most APC parameters are dependent on DDS. You can find more detailed information on DDS-

dependent parameters of APC for example in the SINAMICS S120_S150_List_Manual. If a

DDS switchover is parameterized, then the corresponding APC parameters must also be

copied to the data sets.
