Synchronization/Registration Controller with PLC

The CX-1200 is a Synchronizing Controller. It controls the Follower machine in a Lead-Follow machine coordination process. It will command the Follower to match both speed and phase as it tracks the Lead machine, to achieve automatic synchronization between the machines.

Typical applications include:

• Packaging
• Filling
• Transfer conveyors
• Wicket ovens
• Flighted conveyors with cleats or pockets
• Overhead chains with hooks or grippers

The Lead and Follow machines may be of similar construction, or may be completely different designs, with different motor drives, gear ratios, or process functions.

The CX-1200 uses four 4 basic signals. An encoder device on each machine gives high resolution speed information, and also provides a tracking signal to assist the position control. Two marker pulses (photo eyes, or prox switches) give precise positional information. These synchronization pulses, also called job-space markers, permit automatic alignment of the correct machine phase or position lock. The follower machine can start/stop with the lead machine, or it can be started at random into a "running lead" and still achieve synchronization.

• Synchronization or Registration Control.
• Lead/Follow machines can be similar or very different designs or functions.
• Electronic Phase Shifting and Line Shafting functions.
• Learn and Trend Modes for web stretch or variable configurations.
• Pre-Programmed... no code to write.
• Menu Driven Operator Interface for Setup & Monitoring.
• Integrated PLC Control.
• On-the Fly Reconfiguration Parameter Blocks.
• Fully Isolated Analog and Digital I/O.
• Optional DeviceNet® Network Card.

The CX-1200 is a Universal Controller that can operate through a DC, DC Regen, AC Inverter, AC Vector Drive, or Servo controller. It can be used to retrofit old drives, or work with the latest digital drive products of any brand.

The built-in operator's interface, with keypad, multi-line display, and help screens make set-up and operation simple. A PLC function can help customize the application or coordinate with other machine control devices. Automatic Learn Mode, Trending Mode, or Fixed Ratio Modes allow it to adapt to any machine configuration. Multiple configurations or Set points can be pre-programmed, and changed on-the-fly.

Advance /Retard functions permit operator supervision when desired.

Serial link, or optional remote analog signal, or optional DeviceNet card further enhance integration with host control schemes.

The CX-1200 control is housed in a ½ DIN vertical instrument enclosure with embedded LCD multi-line operator interface. The integrated display and keypad panel gains access to numerous control and monitor parameters through a menu driven screen format. Individual application requirements are met by simply accessing the relevant screen and code parameter, and then entering the appropriate numerical value. Because the CX-1200 control is pre-programmed, applications can be commissioned in a matter of minutes once the control has been installed. A full compliment of monitor parameters are available to verify operation and assist with diagnostics.

The CX-1200 control has a serial port for RS485 communication. ContrexHost software, when installed on a Windows PC or laptop, allows you to initiate commands, change or monitor the complete set of CX-1200 parameters, and load/save setup values.

• Features:
  Pre-programmed control algorithms for Fixed machine designs, or Learn variable configurations, or Trend to adjust for web stretch or shrink.
• Up to eight user defined parameter configuration blocks with on-the-fly digital input for easy reconfiguration.
• Analog card accommodates remote input signals for some phase adjustment features.
• The precision Speed/Position frequency inputs utilize many types of encoder signals including quadrature, open-collector and differential line drivers.
• Phase sensors (Job Space Marker Pulses) can be photo-eyes, prox switches, etc. detecting a machine element (flag) or the target product itself.
• Eight programmable digital outputs are provided for drive control and alarm functions.
