We asked customers what they would like to see improved with our EH series heavy payload SCARA Robots. Two requests came out loud and clear. More payload and more J4 inertia capabilities. The E2H853S and E2H853C SCARA Robots are the answer to these customer requests. They are made for applications where heavy payload and high inertia specs are required. While holding a payload of up to 44 pounds (20 Kg), the E2H853S and E2H853C robots can maintain a +/- 0.025mm (0.001 inch) repeatability. We also improved the J4 inertia spec by over 4.5x as compared to the EH series robots making the E2H the most robust Heavy Duty SCARA robot in the industry. Bring this together with absolute encoders all running on our popular RC420 and RC520 PC based controllers and you've got a robot ready to perform at all new levels in new applications.

E2H853 Specifications

The E2H853 Robot is a four axis unit with high torque AC servo motors for reduced maintenance and harmonic drives for increased speed and reliability. E2H853 Robots come in two models: E2H853S (standard configuration) and E2H853C (cleanroom configuration). E2H853S robots have a horizontal reach of 850mm and a Z Axis vertical stroke of 340mm. The E2H853 Robots were made for applications which require heavy payloads and high J4 inertia capabilities. Our E2H853 robots are quickly becoming very popular as customers challenge our SCARA robots to handle heavier payloads for medium sized yet still high precision assembly and material handling.

Powerful Controls

EPSON is the leader in PC based controls with 2 basic offerings: the RC420 compact PC based controller, and the RC520 expandable PC based controller. Both the RC420 and RC520 controllers are based on our easy to use EPSON RC+ Robot Control Software. The fundamental difference between the 2 controllers is size (the RC420 is a single box controller just a little larger than an industrial PC and the RC520 is a 2 box solution) and expandability (the RC420 has 4/3 available ISA/PCI slots but the RC520 has 7 ISA and 4 PCI slots available for expansion). As a leader in PC based controls, our products not only give access to the thousands of 3rd party products available for the PC but we have focused on ease of use to help reduce learning and development time. As a result, many of our customers have experienced significant reductions in development time due to the ease with which our robots can be programmed. With integrated options such as Vision Guide for robot guidance and inspection applications, VB Guide Active X controls, Ethernet I/O, Force Sensing and others, EPSON RC+ is not only easy to use but also flexible in the different applications it helps to solve.

Z-Axis Stroke and Features

The Z-Axis for the E2H Robots comes standard with 340mm of stroke (290mm for the class 10 cleanroom models). This axis includes a brake that engages to hold tooling and payloads in place when servo motor power is removed. A brake release button is easily accessible on top of the axis for quick release and the quill is hollow which allows easy channeling of electrical and pneumatic lines.

Fast Tool Rotation

Cycle time is the name of the game and just moving quickly in the XY plane isn't enough to meet the tough cycle time requirements of today's applications. This is why U Axis (or the tool rotational axis) speed is so important for most applications. The E2H Robots U Axis travels a full + 360 degrees and with a top speed of 1428 deg/second is over 200 deg/second faster than most competitive models which translates to more parts processed per hour.

Absolute Encoders

All E2H Robots come standard with Absolute Encoders. This means that they don't have to be sent to a home position when first powering the controller up. This can save valuable time during startup each day. Just power the RC420 or RC520 controller on, and the E2H Robots are ready to begin their work for the day.

Class 10 Clean Room Capable

The E2H853C Robots are Class 10 cleanroom versions of the standard E2H853S Robots. The only specification difference is that the Z-Axis stroke is 290mm on the E2H cleanroom/ESD Robots vs. 340mm on the standard configuration E2H Robots. With the introduction of the E2 Series Robots all class 10 cleanroom robots now also come standard as ESD compliant which make them ideal for sensitive applications where static electricity can cause defective parts such as the hard disk industry. The E2H853C Cleanroom Robots are also available at remarkably affordable prices.
