In this situation, the rotary cut axis should decelerate first in the adjustment area and then accelerate to
the synchronous speed. If the cutting length is far greater than rotary cut roller circumference, the roller
may decelerate to 0 and stay still for a while; and then accelerate up to the synchronous speed. The
greater the cutting length is, the longer the roller stays.

Additionally, when rotary cut function is started or broken off, the cam curves used are different.

4. The entry curve
It is the rotary cut curve when rotary cut function is started.
The curve is the rotary cut function entry curve. When the rotary cut function is started up, the rotary cut
axis will follow the feed axis to rotate according to the curve. The entry position is based on the rotary cut
axis. For the single knife, the cutting position is directly below the rotary cut roller if the entry position is
over the rotary cut roller in the following figure. Before the rotary cut function is started up, the knife must
be turned to the upper of the rotary roller. Otherwise, the cutting may happen in the adjustment area.
