December 2001 The Control Loop 6 – 117
7 7 7 7 With MP1095.x you select the single or double filter. The HSC filter is
switched on with MP1094.
MP1095.1 is effective in the Manual, Handwheel, Incremental Jog
Positioning and Reference Mark Traverse modes. MP1095.0 and MP1094
are effective in the Program Run, Single Block, Program Run, Full Sequence
and MDI modes. If MP1094 is used, MP1095.0 is without effect.
Example:
Set the double filter in the Program Run modes for a smooth traverse
(MP1095.0 = 1), or set the single filter in the Manual mode for a shorter
deceleration path (MP1095.1 = 0).
7 7 7 7 Test the three filter settings using a test part made of short line segments.
• Single filter
• Double filter
• HSC filter
The nominal position value filters function in all operating modes (even in rapid
traverse). For RIGID TAPPING (Cycle 17), the nominal position value filter is
automatically switched off.
Note
If you have selected the best nominal position value filter for your
application, please note that your input value can be overwritten by the
machine user through Cycle 32. If you have switched off the nominal
position value filter (MP1096 = 0), the machine user can also switch it on
using Cycle 32.
