General safety guidelines

1

Please observe all the relevant safety instructions to avoid personal and/or material damage. In particular, you must observe the safety instructions and notes regarding the powerful permanent magnets installed in the rotor of the built-in torque motor.

The rotor is secured in the stator by means of transportation locks and a spacer film. The original packaging for the built-in torque motor and the transportation locks (incl. the screws) are required for storage/transport purposes and should, therefore, be kept in a safe place. This documentation should also be kept in a safe place and made available to the personnel responsible.

Residual risks of power drive systems

When carrying out a risk assessment of the machine in accordance with the EU Machinery Directive, the machine manufacturer must consider the following residual risks associated with the control and drive components of a power drive system (PDS).

1.Unintentional movements of driven machine components during commissioning, operation, maintenance, and repairs caused by, for example:

Hardware defects and/or software errors in the sensors, controllers, actuators, and connection technology

Response times of the controller and drive

Operating and/or ambient conditions not within the scope of the specification

Parameterization, programming, cabling, and installation errors

Use of radio devices / cellular phones in the immediate vicinity of the controller

External influences / damage

2.Exceptional temperatures as well as emissions of light, noise, particles, or gas caused by, for example:

Component malfunctions

Software errors

Operating and/or ambient conditions not within the scope of the specification

External influences / damage

3.Hazardous shock voltages caused by, for example:

Component malfunctions

Influence of electrostatic charging

Induction of voltages in moving motors

Operating and/or ambient conditions not within the scope of the specification

Condensation / conductive contamination

External influences / damage
