  • Page 8 Precautions for Safety Always read the specifications issued by the MTB, this manual, related manuals and attached documents before installation, operation, programming, maintenance or inspection to ensure correct use. Understand this numerical controller, safety items and cautions before using the unit. This manual ranks the safety precautions into "DANGER", "WARNING"...
  • Page 9 For Safe Use MITSUBISHI CNC is designed and manufactured solely for applications to machine tools to be used for industrial purpos- Do not use this product in any applications other than those specified above, especially those which are substantially in- fluential on the public interest or which are expected to have significant influence on human lives or properties.
  • Page 10 3. Items related to prevention of bodily injury or property damage DANGER When transporting or installing a built-in IPM spindle or linear servomotor, be careful so that your hand or property is not trapped in the motors or other metal objects. Also keep the devices with low magnetic tol- erance away from the product.
  • Page 11 CAUTION Do not transport the controller or drive unit by suspending or holding the connected wires or cables. Do not hold the front cover when transporting the unit, or the front cover could come off, causing the unit to drop. Install on a non-combustible place where the unit's or motor's mass can be withstood according to the in- struction manual.
  • Page 12 CAUTION Following the UN recommendations, battery units and batteries should be transported based on the inter- national regulations such as those determined by International Civil Aviation Organization (ICAO), Interna- tional Air Transport Association (IATA), International Maritime Organization (IMO) and U.S. Department of Transportation (DOT).
  • Page 13 CAUTION Carry out wiring so that there is no possibility of short circuit between wires, nor of dangerous state. Use wires and cables whose wire diameter, heat resistance level and bending capacity are compatible with the system. Ground the device according to the requirements of the country where the device is to be used. Wire the heat radiating fins and wires so that they do not contact.
  • Page 14 (4) Set up WARNING Do not cancel the emergency stop before confirming the basic operation. Always set the stored stroke limit. Failure to set this could result in collision with the machine end. CAUTION If the battery low warning is issued, save the machining programs, tool data and parameters in an input/ output device, and then replace the battery.
  • Page 15 (6) Usage CAUTION Use C80 in an environment that meets the general specifications contained in "C80 Series Connection and Setup Manual". Using C80 in an environment outside the range of the general specifications could result in electric shock, fire, operation failure, and damage to or deterioration of the product.
  • Page 16 CAUTION Use a noise filter, etc. to reduce the effect of electromagnetic disturbances in the case where electromag- netic disturbances could adversely affect the electronic devices used near the drive unit. Use the drive unit, motor and each regenerative resistor with the designated combination. Failure to ob- serve this could result in fires or faults.
  • Page 17 (8) Maintenance, inspection and part replacement CAUTION Periodically back up the programs, tool data and parameters to avoid potential data loss. Also, back up those data before maintenance and inspections. The electrolytic capacitor’s capacity will drop due to deterioration. To prevent secondary damage due to capacitor's faults, Mitsubishi recommends the electrolytic capacitor to be replaced approx.
  • Page 18 (9) Disposal CAUTION Take the batteries, etc. off from the controller, drive unit and motor, and dispose of them as general indus- trial wastes. Do not alter or disassemble controller, drive unit, or motor. Collect and dispose the spent batteries according to local laws. Dispose the spent cooling fan according to local laws.
  • Page 20 Treatment of waste The following two laws will apply when disposing of this product. Considerations must be made to each law. The following laws are in effect in Japan. Thus, when using this product overseas, the local laws will have a priority.
