Pro-Set 200 Injection Molding Control System

Advanced Process Control with ERC2 – Expert Response Compensation

ERC2 is the second generation of Allen-Bradley’s patented Expert Response Compensation closed-loop control technology. It is an advanced control algorithm which provides automatic tuning of the pressure and velocity loops associated with clamp, injection, and ejector motion. It: •

eliminates the need to manually tune pressure and velocity loops, resulting in simplified machine setups in less time

•

measures machine performance during each cycle and compares it with desired molding parameters. Based on profile configuration, ERC2 provides the control outputs to achieve desired setpoints

•

informs an operator if machine performance appears to fall outside of calculated machine capabilities

ERC2 is a one-button automatic tuning feature that frees you from the tedious and complex process of tuning control systems and lets you concentrate on the quality of parts being produced. As a result, you will experience: •

greater process stability • increased production yields • lower scrap rates • simplified machine operation

Profiled Action for Better Injection and Faster Cycles

Profiling lets you configure the operation of screw, clamp, and ejectors for faster, smoother, molding cycles. We provide profiling screens where you subdivide machine action into position segments, each having a pressure or velocity setpoint. This lets you manipulate hydraulic pressure and/or velocity of the injection ram, allowing you to mold even the most complex parts with the most difficult of materials. For example, you can divide the injection phase into 5 segments and tailor the speed of the injection shot to the characteristics of your mold and/or material. Injection Profile segment 5

There is a corresponding velocity setpoint and pressure setpoint associated with each position setpoint. You use the corresponding velocity and pressure setpoints to go from one position to theprofile next (and to theeither next velocity (Vel) or The entire controls profile). Transfer a transition to the velocity or pressure (psi) iswith a corresponding nextpressure selectedsetpoint profile. associated with each position (Pos) setpoint.

System Expansion to Match Your Machine

Pro-Set 200 software runs on an SLC 5/04P processor, part of Allen-Bradley’s standard SLC architecture This architecture offers expansion and configuration flexibility. System I/O can range from as few as 7 I/O slots in an SLC chassis to multiple chassis with up to 30 slots. This means that Pro-Set 200 can be used in applications requiring extremely high I/O counts or unique I/O configurations. All standard SLC I/O and specialty modules can be integrated into your Pro-Set 200 system.

Precise Temperature Control

The Allen-Bradley Barrel Temperature Module (1746-BTM) is specifically designed for the thermal characteristics of temperature zones associated with plastics molding machines and extruders. A patented cold- startup routine is designed to bring machine temperature zones up to setpoint faster than traditional tuning methods with less overshoot or temperature oscillation. The BTM’s autotuning functions ensure that temperatures are controlled even when process conditions change or environmental conditions would otherwise cause an undesired variance from setpoint. The BTM, when used in a Pro-Set 200 system, provides one-touch automatic temperature control and tuning. Machine operators need only turn on the temperature zones and BTM takes care of the rest. The BTM: •

is easy to use • has resolution of 0.1 degree C / F • is optimized for your process You would set up and monitor temperature control loops with this PanelView screen, included in the set of Pro-Set 200 operator screens.

An Easy-to-use Control System

Menu-driven screens step operators and setup personnel through a logical sequence of the displays necessary to configure a machine, set up a new mold, or diagnose processing problems. Pro-Set 200 offers mold/part storage making mold changes quick and easy.

Communication Networks and Software to Gather Process Data

Whether you need to gather information for process analysis, production monitoring, or integration into plant-wide information networks, Allen-Bradley networking strategies offer a variety of physical connection schemes and data transfer protocols. Since information processing requirements vary, it is extremely valuable to have choices. Allen-Bradley offers solutions including DeviceNet, ControlNet, Ethernet, Data Highway, and others which give you options when networking your injection molding operation. We also recommend Rockwell Software products such as RSTrend and RSView for production monitoring and process analysis.

Lower Cost

In addition to being a cost effective system at time of purchase, our SLC-based system offers lower life-cycle costs than most other control choices since it relies on the same modules and technologies employed in thousands of applications throughout the industry. You get the benefit of worldwide availability of replacement parts and support services from engineers who are experienced with Allen-Bradley / Rockwell Automation products.

This Hardware or Software:

Does the Following:

SLC 5/04P Processor (1747-L542P)

executes the sequence logic which controls the injection molding machine. Embedded within this processor are the ERC2 algorithms which control the pressure and flow valves for the injection, clamp, and ejector phases.

Fast analog I/O module (1746-FIO4V or 1746-FIO4I)

accepts position and pressure inputs and provide analog output signals to the proportional valves which control velocity and pressure. You need a least one FIO4V or FIO4I module for each controlled phase (pressure and position inputs and pressure and velocity outputs). To select these modules: – If your valves require and/or your sensors p roduce10V dc signals, use FIO4V – if your valves require and/or your sensors pr oduce 4-20mA signals, u se FIO4I To control all three phases (inject, clamp, eject) with pressure/position inputs and pressure/flow outputs, you need at least three modules. More may be required for other I/O combinations.

Temperature control module (1746-BTM)

provides temperature control for the barrel of the injection molding machine. These modules contain specialized start-up and auto-tuning algorithms which have been optimized for barrel temperature control. Each module controls four temperature loops using either J or K thermocouples (grounded or ungrounded). The ladder logic and PanelView screens accommodate eight temperature loops. Important: Separate output modules provide the time-proportioned (on/off) or analog outputs for the temperature loops. BTM modules do not have outputs.

PanelView 550 or 900 operator interface

lets you enter and modify profile and temperature setpoints, see alarms, view production data, etc.

How Pro-Set 200 Works

7

The following diagram illustrates how Pro-Set 200 works. Important: The processor uses selectable-timed-interrupt (STI) files to provide fast I/O updates from/to fast analog I/O modules. The processor interrupts the main program scan at timed intervals and goes to the STI file to read inputs and process outputs. This ensures a fast, repeatable response for STI functions. 2. Ladder logic scales position and pressure inputs and stores scaled values in the data table.
