Overview

The Robot Safety Module is the interface between Vention’s MachineMotion 2 controller & Vention’s partner robots’ safety interfaces. The Robot Safety Module manages the safety fault events that happen on the machine to safely stop both the MachineMotion 2 controller and the robot. With the Robot Safety Module connected in Vention’s safety chain, a safety event from the robot will stop the MachineMotion 2 controller and a safety event from Vention’s safety chain will also stop the robot. The Robot Safety Module also serves as an Ethernet switch between Vention’s Pendant, MachineMotion 2 controller and the robot.

Features

Safety Data

The Robot Safety Module is used to propagate safety signals between :

  • The SAFETY IN port to the TO ROBOT port
  • The FROM ROBOT port the SAFETY OUT port; and
  • The SAFETY IN port to the SAFETY OUT port.

For each of these functions performed by the Robot Safety Module, safety data can be found in the following table:

Function PL Cat. MTTFd DCavg
From Robot to Safety OUT e 3 128.3 98.72%
From Safety IN to To Robot e 3 65.8 98.90%
From Safety IN to Safety OUT e 3 126.1 98.81%

The above information have been calculated based on the following operation conditions:

dop 365 days/years
hop 24 hours/days
tcycle 8640 s/cycle
