4. Motion Control Instructions
DVP-MC operating manual 4-145
In this situation, feed axis and rotary cut axis in sync area and non-sync area keep synchronous in speed.
The rotary cut axis does not need to make any adjustment.
Long material cutting
When the cutting length is greater than the knife roller circumference, the rotary cut curve for any cycle is
shown below.
In this situation, rotary cut axis should decelerate first in adjustment area and then accelerate to synchronous
speed. If the cutting length is far greater than rotary cut roller circumference, the roller may decelerate to 0
and then stay still for a while; finally, accelerate up to synchronous speed. The greater the cutting length is,
the longer the roller stays.
