Servo Robots Feature Powerful Controllers

E-Series robots from Engel are designed for use with any make of injection molding machine. There are three models available: the standardERC-E servo robot for machines from 28 to 6000 tons, the high-speed ERC-EH servo robot for machines from 28 to 300 tons and the cost-effectiveERC-EA robot with asynchronous vector drive (ac motor) for machines from 28 to 300 tons (contact Engel directly for specific pricing information; use the Key Contact Directory on p 35).

To address space issues, Engel reduced the basic lengths of the linear arms without compromising available stroke.

The control system is based on a 64-bit RISC-based controller, upgraded from the previous 32-bit architecture. This upgraded processing capacity is said to increase the precision of the E-Series, with repeatability rated at ±0.002 in.

E-Series robots can have up to six independently programmable servo-driven axes (three linear and three rotational), and the controller has the processing power to deliver simultaneous motion along all six axes.

There are a number of intuitive software programs offered with these robots, including a menu-driven interface with a library of standard sequences and teach programming. When mounting an E-Series robot on an Engel machine, the robot can be set up through the machine control and both machine and robot programs can be stored together on a floppy disk.

For non-Engel machines, the robots come with the new HT511 pendant controller, which has a 640 x 400 VGA electro-luminescent display. The 64-bit CPU is integrated into the pendant.

The control system also offers two CAN fieldbus ports, which allow molders to easily tie upstream and downstream automation into the robot control system for a completely automated cell.
