3.12.2.3 Bell Feed Acceleration

When the acceleration value is negative (high speed high precision activated), can additionally add bell feed acceleration. So that the axial motion of the feed is further buffered, but with the relative small loss of precision as expense. The larger the buffer, the greater the loss of accuracy. Bell feed acceleration setting value is time constant (ts). The unit is 0.001 second.

Note:

Bell feed acceleration can be set by "Machine Parameters→High Speed High Precision Profile", dialog box bell acceleration deceleration column.
