Limitations, 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.
Notice | |
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
 | Axis exchange commands deactivate the Vibration Guard. |
Axis exchange commands deactivate a Vibration Guard if it was activated at that time. If the Vibration Guard is to remain activated after an axis exchange, it must be re-activated by a corresponding #VIB GUARD command. If the Vibration Guard was only activated in the axis lists (P-AXIS-00588), the Vibration Guard will remain activated automatically after an axis exchange.
