Robot Monitoring Unit

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

Vision System NV-Pro

VISION SYSTEM -NV PRO

The advanced features of the Nachi FD11 Controller features allows for simple connection to any vision system using an Ethernet or Serial connection.   For even more performance, the Nachi FD11 Controller also features extended vision guidance capabilities with the fully integrated vision system NV-Pro.

Users can develop application software to connect to the FD controller and external devices, such as joysticks and cameras.

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

NV Pro is Nachi’s proprietary vision system, built into the controller and Teach pendant for ease of use. NV Pro is a wholly integrated solution capable of 2D & 3D vision functions.

Technical highlights:

  • The automatic exposure function improves tolerance to ambient light fluctuations

  • Improved hardware performance and faster I/O control significantly shorten measuring time

  • Camera images can be displayed on the teach pendant

  • It can be programmed from the teach pendant

This product is an API (Application Programming Interface) designed to create a software tool for controlling a NACHI-Fujikoshi robot from a computer. Connecting a laptop and a CFD controller with an Ethernet cable makes it possible to develop software for controlling the robot from the computer. It enables the development of applications to meet different requirements, such as enhancing the functionality of current features, like interacting with a visual device (user task) and designing a customized interface screen, enabling remote control from a computer, and ensuring traceability. Examples of programming languages could include C++ and Labview."

Monitoring function of robot operation

• Indication of robot move command

• Acquisition of robot status (Input/output signals, Variables, Shift Values)
