2.3Basic information

@ WARNING

GREAT MASS OR FALLING PARTS

Consider the mass of the axis when mounting it. It may be neces- sary to use a crane.

Mount the axis in such a way (tightening torque, securing screws) that the axis and mounted parts cannot come loose even in the case of fast acceleration or continuous vibration.

Note that vertically installed linear axes may lower unexpectedly.

Failure to follow these instructions can result in death, serious injury or equipment damage.

@ WARNING

LOSS OF CONTROL

The designer of any control scheme must consider the potential failure modes of control paths and, for certain critical functions, provide a means to achieve a safe state during and after a path failure. Examples of critical control functions are EMERGENCY STOP, overtravel stop, power outage and restart.

Separate or redundant control paths must be provided for critical functions.

System control paths may include communication links. Consid- eration must be given to the implication of unanticipated transmis- sion delays or failures of the link.

Observe the accident prevention regulations and local safety guidelines. 1)

Each implementation of the product must be individually and thor- oughly tested for proper operation before being placed into serv- ice.

Failure to follow these instructions can result in death or serious injury.

1)For USA: Additional information, refer to NEMA ICS 1.1 (latest edition), Safety Guidelines for the Application, Installation, and Maintenance of Solid State Control and to NEMA ICS 7.1 (latest edition), Safety Standards for Construction and Guide for Selection, Installation for Construction and Operation of Adjustable- Speed Drive Systems.
