Precautions During Maintenance and Inspection Do not change the wiring during the power-on process. Otherwise, it may cause electric shock or injury. Danger Wiring or inspection operations should be performed by a professional technician. Failure to do so may result in electric shock or product failure. Warning Attention Make sure that the (CHARGE) light turns off after the power is turned off for at least 10 minutes, and then proceed with wiring and inspection. Even if the power is turned off, high voltage may remain inside the servo unit. Therefore, do not touch the power terminals while the (CHARGE) light is on. Otherwise, it may cause electric shock.
When replacing the Servo Unit, make a backup copy of the Servo Unit parameters before replacing it. Copy the backed-up parameters to the new Servo Unit, and make sure that the copy operation is completed correctly. If the backed-up parameters are not copied or the copying operation is not completed correctly, it will cause damage to the machinery and the unit, and thus it will not operate properly. Notice Please remove static electricity before operating the buttons and switches inside the front cover of the servo unit. Otherwise, it may cause damage to the machine.
Precautions Related to Handling in Case of Abnormalities Danger When the safety device (circuit breaker and fuse for wiring) set on the power line acts, please turn on the power supply of the servo unit after eliminating the cause. In addition, 8 SD700 Series Servo Technical Manual use safety devices (external brakes and counterweights, etc.) to prevent the movable part of the machine from falling off. Notice For gain adjustment when the system starts, check the torque waveform and speed waveform with a measuring instrument to make sure there is no vibration. If vibration occurs due to high gain, the servo motor may be damaged prematurely. Do not turn ON/OFF the power frequently.
After starting actual operation (regular operation), the power supply should be turned ON/OFF at intervals of at least 1 hour (approximate standard). Do not use this product in applications where the power supply is turned ON/OFF frequently. Otherwise, it may cause the components inside the servo unit to be damaged prematurely.
