Use filters only if the P factor can be significantly increased!
After finding the oscillation frequencies, several filters can be activated.
On the control, enter the determined filter type (MP2562.x to MP2566.x),
the determined center frequency (MP2552.x to MP2556.x), the determined
bandwidth (MP2572.x to MP2576.x) and the determined damping
(MP2542.x to MP2546.x).
Adjusting
synchronous and
asynchronous
motors
Synchronous and asynchronous motors are adjusted as described in the
TNCopt User's Manual.
If a sufficiently short enough rise time is not achieved (approx. 3 ms), use a
filter (see "Setting the filters in the speed controller" on page 1134). Using a
filter also results in an increased P factor. The I factor must then be
redetermined.
In most cases automatic adjustment of synchronous and asynchronous
motors determine rise times that are too short (< 2 ms). Rise times that are
too short result in irregular control responses. In this case both the P and I
factors must be reduced (until a rise time of approx. 2 ms is achieved).
