Summary of Contents for Mitsubishi Electric MDS-EX-CV Series

  • Page 2 Introduction Thank you for selecting the Mitsubishi numerical control unit. This instruction manual describes the handling and caution points for using this AC servo/spindle. Incorrect handling may lead to unforeseen accidents, so always read this instruction manual thoroughly to ensure correct usage. Make sure that this instruction manual is delivered to the end user.
  • Page 3 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 4 The signs indicating prohibited and mandatory matters are explained below. Indicates a prohibited matter. For example, "Fire Prohibited" is indicated as Indicates a mandatory matter. For example, grounding is indicated as The meaning of each pictorial sign is as follows. CAUTION rotated Danger Electric CAUTION...
  • Page 5 WARNING  Electric shock prevention Make sure the power is shut OFF before connecting a unit and a motor to the power. Do not open the front cover while the power is ON or during operation. Failure to observe this could lead to electric shocks.
  • Page 6 WARNING  Injury prevention 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.
  • Page 7 CAUTION  Fire prevention Install the units, motors and regenerative resistor on non-combustible material. Direct installation on combustible material or near combustible materials could lead to fires. Always install a circuit protector and contactor on the servo drive unit power input as explained in this manual.
  • Page 8 CAUTION  Various precautions Observe the following precautions. Incorrect handling of the unit could lead to faults, injuries and electric shocks, etc. (1) Transportation and installation Correctly transport the product according to its weight. Use the motor's hanging bolts only when transporting the motor itself. Do not use the motor's hanging bolts to transport a motor with other parts installed, or to transport a machine with a motor installed.
  • Page 9 CAUTION Store and use the units under the following environment conditions. Environment Unit Servo motor Spindle motor Operation: Operation 0 to +55°C Operation: 0 to +40°C Operation: 0 to +40°C (with no freezing), (with no freezing), (with no freezing), Ambient temperature Storage / Transportation: -15°C to +70°C Storage: -15°C to +70°C Storage: -20°C to +65°C...
  • Page 10 CAUTION (2) Wiring Correctly and securely perform the wiring. Failure to do so could lead to abnormal operation of the motor. Do not install a condensing capacitor, surge absorber or radio noise filter on the output side of the drive unit. Correctly connect the output side of the drive unit (terminals U, V, W).
  • Page 11 CAUTION (4) Usage methods In abnormal state, install an external emergency stop circuit so that the operation can be stopped and power shut off immediately. Turn the power OFF immediately if smoke, abnormal noise or odors are generated from the unit or motor. Do not disassemble or repair this product.
  • Page 12 CAUTION (6) Maintenance, inspection and part replacement Always backup the programs and parameters before starting maintenance or inspections. The capacity of the electrolytic capacitor will drop over time due to self-discharging, etc. To prevent secondary disasters due to failures, replacing this part every five years when used under a normal environment is recommended.
