Notes on the AL2xxx linear motors

The notes are intended to avert danger and to provide instructions on the handling of the AL2xxx linear motors. They must be followed during installation, commissioning, production, troubleshooting, maintenance and trial or test assemblies.

The linear motors from the AL2xxx series cannot run as stand-alone devices. They must always be installed in a machine or system. After installation the additional documentation and safety instructions provided by the machine manufacturer must be read and followed.

DANGER

Danger to life due to high voltage on the DC link capacitors of the servo drive AX8000!

The DC link capacitors RB+ and RB- and the test contacts DC+ and DC- on the
supply, axis and option modules can carry life-threatening voltages of
≥ 875 VDC.

Take the following measures to avert danger:

  • After disconnecting the servo drive from the mains supply, wait until the voltage has fallen below 50 VDC. Only then is it safe to work.
  • Measure the voltage on the test contacts properly.
  • Secure the work area properly and wear the PPE.

DANGER

Deadly danger due to high voltage on the DC link capacitors of the AX5000 servo drive!

Due to the DC link capacitors, the DC link terminal points "ZK+ and ZK- (DC+ and DC-)" and "RB+ and RB-" may be subject to dangerous voltages of up to 875VDC, even after the servo drive was disconnected from the mains supply.

Take the following measures to avert danger:

  • Wait:
    - 5 minutes in the case of the AX5101 - AX5125 and AX520x
    - 15 minutes in the case of the AX5140/AX5160/AX5172
    - 30 minutes in the case of the AX5190/AX5191
    - 45 minutes in the case of the AX5192/AX5193
    after disconnecting the servo drive from the mains supply. It is only safe to work after the voltage has dropped below 50 V.
  • Measure the voltage on the test contacts properly.
  • Secure the working area properly and wear the PPE.

CAUTION

Proper connection of the protective earth conductor!

Protective earth systems must be connected when installing electrical systems and components.

Please observe the following notes when installing the protective earth conductor:

  • Make sure that the protective earth conductor has been firmly connected.
  • Disconnect the servo drive and all electrical components from the mains supply. Secure the control cabinet and the devices against being switched on again.
  • Wear PPE.

WARNING

Risk of severe burns due to hot surfaces on the linear motor!

During the operation of the system the surface temperature of the linear motors can reach ≥ 50°C. 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 sufficiently. 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.

Notes on the operation of the AL2xxx linear motors:

  • Read this manual carefully and completely before using the linear motor. Notify the responsible sales office immediately if any passages are not understandable. Do not work on the linear motor.
  • Adhere without fail to the climatic conditions for the installation. Further information can be found in the Technical data and Mechanical installation sections.

Note

High temperatures can damage the magnets!

Do not expose the magnets to temperatures ≥ 70°C. This can lead to demagnetization.

NOTICE

Notes on the AL2xxx linear motors 2:

Deadly danger due to the magnetic fields of the linear motor!

The AL2xxx linear motors are equipped with permanent magnets in the magnetic plate. Strong magnetic fields are present here. In the power-off state, the magnetic field strength of the motors results exclusively from the magnetic fields of the secondary part.

There is a particular danger for:

people fitted with cardiac pacemakers
(The cardiac pacemaker can be switched to test mode and thus cause a cardiac arrest!)

People with implanted defibrillators
(The defibrillators can be rendered inoperative by the magnetic field!)

Note

Loss of data due to magnetic fields!

-- Magnetic data storage devices

-- Chip cards with magnetic strips and

-- Electronic devices can be demagnetized by magnetic fields.
There is a risk of the loss of data.

The objects listed above and loose-lying ferromagnetic objects may not be brought any closer than 1 m to the magnetic plates.
The requirements in BGV B 11 applying to magnetic fields and the national regulations applicable in other countries must be observed.

CAUTION

Risk of crushing and injury due to magnets!

The AL2xxx linear motors are equipped with permanent magnets in the magnetic plate. (Crushing) injuries may be sustained during commissioning due to magnetic attractive forces.

Take the following measures to avert danger:

  • Move the magnetic components slowly towards one another.
  • Wear PPE for all work on the magnets!
  • Avoid shocks or jerky contact between magnets. This could lead to splintering and eye injuries. Wear safety goggles.
  • Make sure that there are no ferromagnetic tools or materials nearby in your working environment. These could be attracted by the magnetic field and cause injuries to body parts.

Notes on the transport of magnetic material!

Please observe the IATA regulation 953 when transporting magnetic material. The AL2xxx magnetic plates fall below the limit values and may be dispatched.
