ROBOT MONITORING UNIT

The Robot Monitoring Unit (RMU 20-20 & RMU 20-30) is a Category 4 and PLe compliant system that monitors the robot position and speed so as to shut off the power to the robot when its position or speed are deemed to be irregular

ROBOT MONITORING UNIT

Technical Highlights  

  • Improved safety through dual safety-related signals

  • Utilizes robot position & speed monitoring functions

  •  Reduced safety signal cabling by using Safety Network CIP Safety on EtherNet/IP (Ethernet/IP Safety)

  •  Conforms to International Standard IEC 61508 SIL3 and Category 4 of ISO 13849-1 Ple

  •  ISO10218 Conformance supports collaborative work between humans & robots

  • The robot position monitoring system consists of safety circuits using microcomputers and semiconductors, and input/output signals, redundant safety signals, and other signals from the process control panel are connected as the input/output signals from outside the robot controller.   

 

  • Control signals of the emergency stop button, operation switches, and magnetic switch of the robot controller are connected as the internal input/output signals, and the unit has functions for monitoring the sequence and status. 

 

  •  The robot monitoring unit is connected by a cable to the position encoder of the drive motor so that the unit can monitor the robot operations, and the system ensures that the robot will stop safely when the robot has operated irregularly. 

 

  • User-defined work areas provide improved safety and flexibility not previously available with base limit zone rings and arm clear switches. 

 

  • Multiple work zones can be user-defined to interlock robot motion with peripheral safety equipment such as light curtains, laser sensors, and other equipment  

VISION SYSTEM -NV PRO

Features

High Speed,high-capability systems

  • A visual device has been embedded and unified with an AX control device, realizing high-speed processing. (Measuring Time (compared to conventional devices of our company):2D:60%,3D:83% increase in speed)

​​

Equipped with stereo recognition function

  • Equipped with a part search tool that is not affected by the direction, size, or exterior irregularities of parts         

  •  Uses NACHI developed stereo vision algorithm to measure the 3D position of work

           

  Cross laser 3D sensor

  • Cross laser irradiation makes it possible to recognize the tilt, height, and holes in 3D position. Optimal for removing bulk sheets and boxes                

Outstanding Environmental Resistance 

  • Environmental resistance has been increased 4 times through the automatic exposure function. Able to stably ascertain work even during changes in brightness

 

Easy Operation with robot teach pendant

  • Uses the same operation interface as the AX control device. The robot teach pendant can be used to perform simple operation for all visual devices, including condition settings and programming,

  •  A separate display is not required. Camera images can be displayed in color on the teach pendant, realizing compactness and easy operation
