Restrictions – special features
The FIR filters and the Vibration Guard are different independent functions with similar objectives. Both functions smooth the axis setpoint signal to avoid exciting the machine to vibrations. FIR filters achieve this in the broadband. On the other hand, the Vibration Guard filters specific critical frequencies selectively.
Attention
It is only possible to use FIR filters and the Vibration Guard simultaneously under certain conditions.
The following combinations are not possible and will result in the output of an error message:
- Configuring an FIR filter in one axis and at the same time activating the Vibration Guard in the same axis.
- It is not possible within an NC program to program both #FILTER and #VIB GUARD commands (Error ID 22060).
- If #FILTER commands are used, the Vibration Guard may not be activated in the axis lists.
- If #VIB GUARD commands are used, no filter types may be configured in the axes.
It is permitted to use:
- an FIR filter in one axis and the Vibration Guard in another axis but only if activation takes place exclusively in the axis lists. In this case, neither #FILTER nor #VIB GUARD commands can be used.
Axis exchange commands
Notice
Axis exchange commands disable FIR filters.
Axis exchange commands disable FIR filters that may be enabled at that time. If the filters should remain enabled after axis exchange, they must be re-enabled by a corresponding #FILTER command.
If the FIR filters were only enabled in the axis lists (P-AXIS-00573), the filters remain enabled even after axis exchange.
