  • Page 2 Make sure that this instruction manual is delivered to the end user. Always store this manual in a safe place. In order to confirm if all function specifications described in this manual are applicable, refer to the specifications for each CNC. Notes on Reading This Manual (1) Since the description of this specification manual deals with NC in general, for the specifications of individual machine tools, refer to the manuals issued by the respective machine manufacturers.
  • Page 4 Precautions for Safety Please read this manual and auxiliary documents before starting installation, operation, maintenance or inspection to ensure correct usage. Thoroughly understand the device, safety information and precautions before starting operation. The safety precautions in this instruction manual are ranked as "WARNING" and "CAUTION". DANGER When there is a potential risk of fatal or serious injuries if handling is mistaken.
  • Page 5 Important matters that should be understood for operation of this machine are indicated as a POINT in this manual. For Safe Use Mitsubishi CNC is designed and manufactured solely for applications to machine tools to be used for industrial purposes. Do not use this product in any applications other than those specified above, especially those which are substantially influential on the public interest or which are expected to have significant influence on human lives or properties.
  • Page 6 WARNING 1. Electric shock prevention Do not open the front cover while the power is ON or during operation. Failure to observe this could lead to electric shocks. Do not operate the unit with the front cover removed. The high voltage terminals and charged sections will be exposed, and can cause electric shocks.
  • Page 7 When handling a motor, perform operations in safe clothing. In the system where the optical communication with CNC is executed, do not see directly the light generated from CN1A/CN1B connector of drive unit or the end of cable. When the light gets into eye, you may feel something is wrong for eye.
