dancer position change to calculate material diameter before running the drive.
This is a diameter preset feature without the need for external diameter sensing
devices.
• The PID control provides the flexibility to reset the PID starting point for winding
from the same starting size (empty core, mandrel, etc).
• Overwind/Underwind control is provided by detecting the direction of speed
reference and inverting the PID correction automatically.
• A diameter hold , using PID enable, can be commanded when transient conditions
are known to disrupt the PID regulator, or the feedback is suspected to be
incorrect. An example of this would be on a web break, where a dancer or load cell
would lose contact with the material.
• Regulator gains can be programmed to be dependant on speed, drive variables, or
other external means. This is important to account for varying torque requirements
at a speed point where the roll may have no material buildup or a lot of
material inertia.
• The PI and PD parts of the PID regulator are capable of being separately
enabled.
Examples follow in this section.
