No Abbr. Parameter function and description Mode Default Range Unit
PC89 SPF1 PR special filter setting:
u z y x
yx: the acceleration time limit
PC89.yx = 00: invalid
PC89.yx = 1~7F: acceleration time limit: yx *
10[ms]
With acceleration time limit(0~1270 ms), if the PR(E-
Cam) command changes too drastically, it will cause
mechanical vibration and jeopardize the production.
This
function can control the
acceleration/deceleration within the limit in any time,
smooth the operation, reduce the noise and extend
the lifetime.
This function is different from the general filter: the
traditional filter works regardless the change of
command, which may cause command lag and
reduce system efficiency.
This function only filter when command change
exceeds the limitation. When the variation value is
small, the filter is invalid and no lag occurs. The
definition of this acceleration time is the motor
acceleration time from 0 to 3000rpm. Increasing time
will improve the effectiveness of filter, and also
improve the stability of the acceleration /deceleration
operation.
