Masking the Command Value
The masking windows (max. 4) that can be defined via
P-0-1207, Lower
limit of velocity masking window
and
P-0-1208, Upper limit of
velocity masking window
are used to suppress resonance phenomena
of a machine or in an installation. The drive should not be permanently
moved at velocities within these windows. A velocity command value
within the value range of one of the 4 definable windows is either reduced
to the lower limit P-0-1207 or increased to the upper limit P-0-1208.

The subsequent ramp generator passes the range of the velocity window;
the values indicated in
P-0-1209, Acceleration factors for velocity
masking window
have a multiplying effect on the acceleration values of
the ramp generator (P-0-1201, P-0-1203, P-0-1211 and P-0-1213).
