Special safety instructions for the AL38xx
The safety instructions are designed to avert danger and must be followed during installation, commissioning, production, troubleshooting, maintenance and trial or test assemblies.
The linear servomotors from the AL3xxx series are not capable of running independently and are always installed into a machine or system. After installation the additional documentation and safety instructions provided by the machine manufacturer must be read and followed.
WARNING- Negligent, improper handling of the linear servomotor and bypassing of the safety devices can lead to personal injury or death through electric shock.
- It must be ensured that the protective conductor has been firmly connected.
- The machine manufacturer must prepare a hazard analysis for the machine, and must take appropriate measures to ensure that unexpected movements cannot lead to injury to persons or to objects.
- Power leads may be live, even if the motor is not running. Never undo the electrical connections to the motor when it is live. Under unfavorable conditions arcing may occur, resulting in injury and damage to contacts.
- Disconnect the linear servomotor from the servo drive and secure it against reconnection before working on electrical parts with a voltage > 50 V.
- The DC link voltage of the servo drive may exceed 890 VDC. Wait until the DC link capacitors are discharged before touching live terminals. The voltage measured between the DC+ and DC- terminals (X02) must have dropped to below 50 VDC.
WARNING- The surface temperature may exceed 50 °C, resulting in a risk of burns.
- Avoid touching the housing during or shortly after operation.
- Leave the linear servomotor to cool down for at least 15 minutes after it is switched off.
- Use a thermometer to check whether the surface has cooled down sufficiently.
- Carefully read this manual before using the linear servomotor thoroughly, paying particular attention to the safety instructions. In the event of any uncertainties please notify your sales office immediately and refrain from working on the linear servomotor.
- Only well trained, qualified electricians with sound knowledge of drive equipment may work on the device.
- Adhere without fail to the climatic conditions for the installation. Further information can be found in the chapter Technical data and Mechanical installation.
- If a linear servomotor is installed in a machine it must not be commissioned until proof of compliance of the machine with the latest version of the EC Machinery Directive has been provided. This includes all relevant harmonized standards and regulations required for implementation of this Directive in national legislation.
Treat the components of the linear servomotor with care, both in the packed and unpacked state. The magnet yokes are particularly sensitive. Never let the magnet yokes fall on the floor.
The magnets should never be exposed to temperatures above 70° C. They can become demagnetized at higher temperatures.
CAUTION- The magnetic plates exercise a powerful attractive force on any soft-magnetic materials such as iron. These forces are more than the hand can manage. They can cause serious injuries.
- Do not bring any soft-magnetic objects closer than 10 cm to the magnetic side of the magnetic plates.
- During assembly, the magnet yokes may be subject to mutual attractive forces. The magnets of the magnet yokes may be damaged by the end plate of an adjacent magnet yoke.
WARNINGThe linear servomotor is driven by a servo drive. It is possible for a power failure, or for some other serious fault, to cause the motor to start up automatically. Provide mechanical safety equipment that will protect the motor and your machine from being damaged in such circumstances.
