How to Install and Wire AC Servo Drive Safely?
AC Servo drive is a controller used to control servo motors. Today, more and more users have it. ATO AC servo drives are widely used in automation equipment such as industrial robots and CNC machining centers. The following introduces how to install and wire the AC servo drive correctly.
- Install the Servomotor or SERVOPACK in a way that will support the mass given in technical documents.
- Install SERVOPACKs, Servomotors, regenerative resistors, and External Dynamic Brake Resistors on nonflammable materials.
Installation directly onto or near flammable materials may result in fire.
- Provide the specified clearances between the SERVOPACK and the control panel as well as with other devices.
There is a risk of fire or failure.
- Install the SERVOPACK in the specified orientation.
There is a risk of fire or failure,
- 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.
- If you store or install the product in any of the above locations, the product may fail or be damaged.
- Use the product in an environment that is appropriate for the product specifications.
If you use the product in an environment that exceeds product specifications, the product may fail or be damaged.
- 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.
- Always install a SERVOPACK in a control panel.
- Do not allow any foreign matter to enter a SERVOPACK or a Servomotor with a Cooling Fan and do not cover the outlet from the Servomotor's cooling fan.
There is a risk of failure.
Do not install or store the product in any of the following locations.
- Locations that are subject to direct sunlight
- Locations that are subject to ambient temperatures that exceed product specifications
- Locations that are subject to relative humidities that exceed product specifications
- Locations that are subject to condensation as the result of extreme changes in temperature
- Locations that are subject to corrosive or flammable gases
- Locations that are near flammable materials
- Locations that are subject to dust, salts, or iron powder
- Locations that are subject to water, oil, or chemicals
- Locations that are subject to vibration or shock that exceeds product specifications
- Locations that are subject to radiation
Do not change any wiring while power is being supplied. There is a risk of electric shock or injury.
- Wiring and inspections must be performed only by qualified engineers.
There is a risk of electric shock or product failure.
- Check all wiring and power supplies carefully.
Incorrect wiring or incorrect voltage application to the output circuits may cause short-circuit failures. If a short circuit failure occurs as a result of any of these causes, the holding brake will not work. This could damage the machine or cause an accident that may result in death or injury.
- Connect the AC power supplies to the specified SERVOPACK terminals.
Connect an AC power supply to theL1, L2, and L3 terminals and the L1C and L2C terminals on the SERVOPACK. There is a risk of failure or fire.
- If you use a SERVOPACK with the Dynamic Brake Hardware Option, connect an External Dynamic Brake Resistor that is suitable for the machine and equipment specifications to the specified terminals.
There is a risk of unexpected operation, machine damage, burning, or injury when an emergency stop is performed.
- Wait for at least six minutes after turning OFF the power supply (with a SERVOPACK for a 100V AC input, wait for at least nine minutes) and then make sure that the CHARGE indicator is not lit before starting wiring or inspection work. Do not touch the power supply terminals while the CHARGE lamp is lit after turning OFF the power supply because high voltage may still remain in the SERVOPACK.
There is a risk of electric shock.
- Failures caused by incorrect wiring or incorrect voltage application in the brake circuit may cause the SERVOPACK to fail, damage the equipment, or cause an accident resulting in death or injury.
- Check the wiring to be sure it has been performed correctly.
Connectors and pin layouts are sometimes different for different models. Always confirm the pin layouts in technical documents for your model before operation.
There is a risk of failure or malfunction.
- Connect wires to power supply terminals and motor connection terminals securely with the specified methods and tightening torque.
Insufficient tightening may cause wires and terminal blocks to generate heat due to faulty contact, possibly resulting in fire.
- Use shielded twisted-pair cables or screened unshielded multi-twisted-pair cables for I/O Signal Cables and Encoder Cables.
- Install molded-case circuit breakers and other safety measures to provide protection against short circuits in external wiring.
There is a risk of fire or failure.
