Notes on the AX5000 servo drive

The safety instructions are designed to avert danger and must be followed during installation, commissioning, production, troubleshooting, maintenance and trial or test assemblies.

The servo drives of the AX5000 series are not designed for stand-alone operation and must always be installed in a machine or system. After installation the additional documentation and safety instructions provided by the machine builder must be read and followed.

DANGER

Danger to life due to high voltage at the DC link capacitors of the AX5000 servo drive!

Due to the DC link capacitors, the DC link terminal points “DC+ and DC-” and “RB+ and RB-” may still exhibit life-threatening voltages of 875 V DC/890 V DC, even after the servo drive was disconnected from the supply network. It is only safe to work after the voltage has dropped below 50 V.

Take the following measures to avert danger:

  • After disconnecting the servo drive from the supply network, wait:
    5 minutes for the AX5101…AX5125 and AX520x
    15 minutes for the AX5140
  • Measure the voltage on the test contacts correctly.
  • Secure the working area properly and wear the PPE (personal protective equipment).

WARNING

Serious burns due to hot surfaces on the devices!

The surface temperature of the devices can reach ≥ 50°C during operation of the machine or system. There is an acute risk of sustaining burns to parts of the body and limbs.

Take the following measures to avert danger:

  • Do not touch any components (housing, etc.) shortly after or during operation.
  • Wait until all components have cooled completely. At least 15 minutes.
  • Check the surface temperature with a thermometer.
  • DO NOT wear work gloves with a rubber coating. These can fuse with the skin on account of the high temperature and cause serious injuries.

Notice

Notes on operation of the AX5000 servo drive

Read this manual completely and carefully before using the servo drive. In the event of any uncertainties please notify your sales office immediately and refrain from working on the servo drive.

During the electrical installation it is essential to ensure that the correct fuses/circuit breakers are used between the supply network and the servo drive. Further information can be found in the chapter "Electrical installation".

If a servo drive is installed in a machine it must not be commissioned until proof of compliance of the machine with the latest version of the EU Machinery Directive has been provided. This includes all relevant harmonized standards and regulations required for implementation of this Directive in national legislation.

Notice

Damage to the environment or devices

During installation it is essential to ensure that the specified ventilation clearances and climatic conditions are adhered to. Further information can be found in the chapters "Technical data" and "Mechanical installation".

If the servo drive is operated in contaminated ambient air, the cooling openings must be checked regularly for blockage. These checks should be carried out several times per day.

The servo drives contain components at risk from electrostatic discharge caused by improper handling:

Please ensure you are electrostatically discharged before touching the servo drive directly.

Avoid contact with highly insulating materials (synthetic fibers, plastic film etc.).

Place the servo drive on a conductive surface.

Do not touch the motor connector while the AX5000 is in operation.
