The function "Following error compensation" is an
option. It is an integral part of the "Extended thread
package".
With this function, the following error which occurs during thread cutting is compensated for. It
is thus possible to cut a thread using different speeds and without entering a following error.
This compensation only works with threads with a constant pitch.
The speed should be kept constant within one cut. If the compensation cannot be applied
because no servo gain factor has been entered, alarm 3089 "KV factor for thread too small" is
output.
