Control System for Tool Breakage and Object Monitoring with PROFIBUS Interface or Digital I/Os

BK MIKRO9 integrates almost all features of the known BK MIKRO systems. It is usable for tool monitoring and object or free space monitoring purposes.

The MIKRO9 system contents

• A control unit (BK MIKRO91, BK MIKRO92 oder BK MIKRO93; BK MIKRO9I/O as option)
• A scnanner (TK 7A/RL, TK 8A, TK91A, TK94...)
• Connection cable

The BK MIKRO9 models are suitable for a great variety of monitoring tasks:

• Profibus
  The monitoring is controlled by parameters (angle / tolerance, etc.) from the PROFIBUS master (PLC). In this case an unlimited number of tools can be scanned and the full functionality of the system is available.
  
  Typical application BK MIKRO91
• Parameterization with Desktop Software and Digital I/Os
  The parameterization of the tool / object data is performed on a PC and transmitted to the control unit via USB then actuated digitally (by the PLC) during the application. When connected to the I/0 extension module up to 512 objects / tools can be taught  and monitored via the selection inputs. Depending on the control unit used a full (premium) or limited (basic) functionality is provided.
  
  Typical application BK MIKRO92/93
• Basic Function and Digital I/Os
  For easy setup without a PC the most important functions (clockwise / counter-clockwise rotation of the wand, object or free-space monitoring, adjustment of scanning intensity) can be set on the I/O extension module.
  
  Typical application BK MIKRO92/93 with I/O module

Further Features:

• Setting all parameters via PROFIBUS or configuration software.
• The number of the nominal values which have to be interrogated is unlimited (digital I/Os: 512 tools max.). A single control system is therefore also sufficient if a processing centre is, for example, extended by a further tool magazine.
• The angles measured by the scanner are transmitted to the control over PROFIBUS for evaluation. If the actual value differs from the nominal value, the production process is stopped by the control.
• Diagnostic features easy accessible with the desktop software.
• Axial scanning of the tool tip possible.
• Different types of tools can be checked for damage and correct place in a magazine.
• Wands up to 610 mm length for more space between scanner and tool.
• Monitoring of rotating toos up to min. diameter of 0.3 mm.
• Scanning in clockwise or counter-clockwise direction (depends on scanner version).
• Reverse travel monitoring.
• 8 steps for scanning intensity.
• Cable breakage detection.
• No impact on work process time.
• Air barrier adapter as option to use the tool monitoring system system in surroundings with aggressive coolants.
