    Safety Precautions  Safety Information To prevent personal injury and equipment damage in advance, the following signal words are used to indicate safety precautions in this document. The signal words are used to classify the hazards and the degree of damage or injury that may occur if a product is used incorrectly.
  • Page 5  Safety Precautions That Must Always Be Observed  General Precautions DANGER • Read and understand this manual to ensure the safe usage of the product. • Keep this manual in a safe, convenient place so that it can be referred to when- ever necessary.
  • Page 6 NOTICE • Do not attempt to use a SERVOPACK or Servomotor that is damaged or that has missing parts. • Install external emergency stop circuits that shut OFF the power supply and stops operation immediately when an error occurs. • Select the brake power supply for a Servomotor with a Holding Brake accord- ing to the power supply voltage and capacity required for the Servomotor model, as given in manuals and catalogs.
  • Page 7 If you store the product for more than six months, reapply an anticorrosive coating to machined surfaces, particularly the motor shaft. • Consult with your Yaskawa representative if you have stored products for an extended period of time. ...
  • Page 8 NOTICE • A SERVOPACK or Servomotor is a precision device. Do not drop it or subject it to strong shock. There is a risk of failure or damage. • Do not subject connectors to shock. There is a risk of faulty connections or damage. •...
  • Page 9 Continued from previous page. CAUTION • Do not step on or place a heavy object on the product. There is a risk of failure, damage, or injury. • Do not allow any foreign matter to enter the SERVOPACK or Servomotor. There is a risk of failure or fire.
  • Page 10 Continued from previous page. NOTICE • A Servomotor is a precision device. Do not subject the output shaft or the main body of the Servomotor to strong shock. • Design the machine so that the thrust and radial loads on the motor shaft during operation do not exceed the allowable values given in the catalog.
  • Page 11  Wiring Precautions DANGER • Do not change any wiring while power is being supplied. There is a risk of electric shock or injury. WARNING • Wiring and inspections must be performed only by qualified engineers. There is a risk of electric shock or product failure. •...
  • Page 12 • Whenever possible, use the Cables specified by Yaskawa. If you use any other cables, confirm the rated current and application environ- ment of your model and use the wiring materials specified by Yaskawa or equivalent materials. • Securely tighten cable connector screws and lock mechanisms.
  • Page 13  Operation Precautions WARNING • Before starting operation with a machine connected, change the settings of the switches and parameters to match the machine. Unexpected machine operation, failure, or personal injury may occur if opera- tion is started before appropriate settings are made. •...
  • Page 14 Continued from previous page. CAUTION • When overtravel occurs, the power supply to the motor is turned OFF and the brake is released. If you use the Servomotor to drive a vertical load, set the Servomotor to enter a zero-clamped state after the Servomotor stops. Also, install safety devices (such as an external brake or counterweight) to prevent the moving parts of the machine from falling.
  • Page 15 WARNING • Wiring and inspections must be performed only by qualified engineers There is a risk of electric shock or product failure. • If you replace a Servomotor with a Holding Brake, secure the machine before you replace the Servomotor. There is a risk of injury or equipment damage if the equipment falls.

  • Page 19: Product Handling Precautions

    1 Product Handling Precautions Product Handling Precautions Handling Servomotors Observe the following precautions when you handle Servomotors. • Do not subject the Servomotor to shock. • Do not hold onto the motor shaft or cables when you move the Servomotor. Servomotor Installation Environment Install the Servomotor in the following environments.
  • Page 20 1 Product Handling Precautions • The surrounding air humidity is 20% to 80% relative humidity (with no condensation). • The vibration resistance (vibration acceleration rate) of the Servomotor is based on the flange surface of the Servomotor. The vibration resistance depends on the model.
  • Page 21 The protection class of a Servomotor depends on the model and option specifi- cations of the Servomotor. Confirm the protection class of your Servomotor in the Servomotor manual or catalog, or on Yaskawa’s product and technical information website (http:// www.emechatronics.com/). Observe the following precautions in reference to the protective structure (pro- tection class).
  • Page 22 1 Product Handling Precautions • The protective structure does not apply to the connectors (shown below with dotted circle) on Servomotors that have cables attached. Specified connectors Shaft opening Medium-Capacity Servomotors Specified connectors Connectors Shaft opening Shaft opening Small-Capacity Servomotors with Cables Attached Small-Capacity Servomotors without Cables E-20...

    (http://www.emechatronics.com/). If the application environment makes it difficult to provide an appropriate size of heat sink, contact your Yaskawa representative. Do not place packing or any other insulating material between the Servomotor and heat sink. Doing so will cause the motor temperature to increase, affect resistance to noise, and may cause motor failure.

Enlargement Key slot • When you attach the coupling, do not subject the shaft to shock. When you attach the load, do not exceed the allowable value of the thrust load or radial load specified in the manual or catalog.
  • Page 26 1 Product Handling Precautions • Select a suitable size of coupling for the operating conditions. A coupling that is too large or too small may cause damage. 0.03 mm max. • Rotate both shafts when you center the coupling. • We recommend that you use a dial gauge to check the accuracy of centering, but if using one is not possible, slide the coupling along both shafts and make adjustments so that it does not catch.
  • Page 27 1 Product Handling Precautions • Measure the belt tension at 45 intervals of the shafts. Turn the shafts and take measurements with a belt tension meter at each point. Turn to 45˚ intervals. Belt 8888 Servomotors with Oil Seals If the Servomotor is used where the shaft opening is subject to oil mist, use a Servomotor with an Oil Seal.
