The CLPC^TM  is a series of microprocessor based Closed Loop Positioning Controls. They are commonly used with a clutch/brake indexing drive to accurately stop the drive in position each time, every time. The control counts pulses from an encoder to determine the ultimate time to bring on the brake. The CLPC^TM Control monitors each stop and will make an adjustment to the trigger point to maintain the stop position. This eliminates the need for manual, or other adjustments to compensate for changes in the speed, load, environment, or temperature.

The controls all incorporate a manual adjustment that allows the user to offset the index from the mechanical home position by up to 25% of the total index in either direction.

There are several models of CLPC^TMClosed Loop Positioning Controls to fit a variety of applications.

CLPC^TM Model LC FTL
Feed - to - Length Position Control

• Utilizing a CLPC® LC and PLC the feed to length unit is used to index product to length, stop send an output signal process the next step.
• Closed Loop Positioning feature of the CLPC® LC assures accurate indexing under all conditions.
• Includes HAND OFF AUTO

• A larger freestanding control often used for retrofit applications where the control is added with the clutch/brake.
• Highly noise-resistant with on-board data buffering and differential line driven quadrature signal.
• Zero-power RAM stores encoder position on loss of power, eliminating need to recalibrate after power loss.
• Up to 1000-ft. cable length with differential line driver.
• Includes JOG and HAND OFF AUTO switches
• Adjustable index length and offset from home position on front panel.

• Same as the CLPC® II with the addition of an "In Position" and 4 "Programmable Limit Switch" ouputs.
• Eliminates need to trigger auxiliary devices with rotary limit switches tied to drive shaft, reducing system cost and wiring.
• Allows machine tasks to be done in parallel, with coordinated motion.
• Greatly improves overall machine cycle.
• Delivers an "In Position" signal on completion of the index
• The allowable window for "In Position" is adjustable.

CLPC® ^TM Series III
"Bumpless" dual-speed position control

• Use low speed for soft starts and super-accurate stops.
• Control logic allows programmable overlap of signals to high-speed and low-speed sides of the drive for bumpless speed changes.
• Simple setup using front panel control.
• Available (Model IIIC) with "in position" and programmable limit switch outputs.

CLPC® ^TM Series II Feed-and-Cut
With integrated cut-to-length position control

• Same as the CLPC® II with the addition of an "In Position" and 4 "Programmable Limit Switch" ouputs.
• Eliminates need to trigger auxiliary devices with rotary limit switches tied to drive shaft, reducing system cost and wiring.
• Allows machine tasks to be done in parallel, with coordinated motion.
• Greatly improves overall machine cycle.
• Delivers an "In Position" signal on completion of the index
• The allowable window for "In Position" is adjustable.
