<1> Cutting/rapid feed-forward switching function
The position feed-forward coefficient and the velocity
feed-forward coefficient can also be changed without using fine
acc./dec. To do this, use the cutting/rapid feed-forward switching
function.

<2> TCMD filter switching
When high frequency vibration occurs only in rapid traverse, use
of the TCMD filter, rather than the resonance elimination filter,
is sometimes effective. On the other hand, in cutting feed,
inserting an unnecessary TCMD filter lowers the vibration limit
of the velocity loop gain because of the delay in the filter. In
such a case, using the TCMD filter only for rapid traverse is
effective.
