Safe robot motion

Safety functions for Epson Robots
SAFE ROBOT MOTION

Safe and efficient robotic operations

Whether to increase operator safety or increase productivity, Epson’s safety functions allow the machine to keep running while operators perform their tasks. Operators can work in synchronisation with the machine by reducing risks through safe speed and position monitoring.

Increase your process flexibility and ensure safe robot motion

Monitor robot speed and position with SLS and SLP to increase the safety of the robot, as well as the flexibility of the production process. Completion with simple safety components (laser scanner, light curtain etc.) to fulfil even the highest safety requirements.

Key benefits

Reducing machine downtime

Using Epson’s safety functions, such as SLS and SLP, it is possible to keep the machine running while fulfilling even complex applications

Machine downsizing

Reduce the footprint of the machine by restricting the robot motion in the defined safety zones

More flexible machine layout

Use extended safety functions to make your machine more efficient. Create monitored areas where the robot’s speed is adjusted depending on the situation instead of permanently restrictions with safety fences

Meeting the latest safety requirements

Epson robot systems are certified by TÜV Süd, to meet the latest machine directives and harmonised industrial robot standards EN ISO 10218-1, ISO 13849-1 (PLd, Cat3) and NRTL certification

Safety Limited Speed (SLS)

SLS is a function to monitor the speed of the robot to prevent the robot from exceeding the preset speed limitation.

When triggering SLS via safety components like safety mats, light curtains, etc, the robot speed will be adjusted to a preset value to keep the worker safe while the machine is running.

Safety Limited Position (SLP)

SLP is a function to monitor the robot’s position and the joint angles to prevent the robot from entering the preset restricted area.

The robot avoids the restricted area or uses a different motion path to let the worker do the task in the restricted area and allow easier quality control or material supply.

Safety function manager

One software for all – Epson´s safety function manager is embedded in the robot development software RC+. All related safety functions can be also monitored with RC+ Express.

Easily configure different safe zones like restricted areas, walls and monitored areas of the various robot axis, set the speed parameters for safe limited robot speed and configure the corresponding safety I/Os.

Check the limited positions and restricted areas with the embedded SLP Viewer or monitor them in the RC+ simulator to ensure a smoother and more flexible production process.

See how it works

Configuration of Safe limited speed - SLS

Easily set the safety parameters for Robot speed, tool configuration and define Safety in-/outputs

Configuration of Safe limited position - SLP

Define the restricted areas, robot soft axis limiting and the monitored areas of the robot arm for making sure that synchronised working is possible

Checking Safe limited position with SLP Viewer and 3D Simulator

Use the SLP Viewer and 3D Simulator for a visual inspection of the monitored areas to ensure a smoother and more flexible production process
