    Safety precautions Only qualified personnel should work with the product. Use the product correctly after thoroughly reading the section “Safety precautions.” The precautions described below are intended to prevent danger or injury to the user and other personnel through safe, correct use of the product. Use the product only after carefully reading and fully understanding these instructions.
  • Page 3 Operation • Turn off the driver power in the event of a power failure, or the motor may suddenly start when the power is restored and may cause injury or damage to equipment. • When you want to use the motor in a vertical application, take position holding measures.
  • Page 4 Operation • Use a motor and driver only in the specified combination. An incorrect combination may cause a fire. • To avoid injury, remain alert during operation so that the motor can be stopped immediately in an emergency. • Before supplying power to the driver, turn all control inputs to the driver to “OFF.” Otherwise, the motor may start suddenly and cause injury or damage to equipment.
