Safety notices

After hardware and/or software components have been modified or replaced, it is

only permissible for the system to run up and the drives to be activated with the

protective devices closed. Personnel shall not be present within the danger zone.

Depending on the change made or what has been replaced, it may be necessary

to carry--out a partial or complete acceptance test (see Chapter 4.8 "Acceptance

Before personnel may re--enter the hazardous area, the drives should be tested to

ensure that they exhibit stable control behavior by briefly moving them in both the

plus and minus directions (+/–).

Please note the following when switching on:

The safety functions are only available and can only be activated after the system

has completely booted (powered--up).

The Category 0 stop function according to EN 60204--1 (defined as STO in Safety

Integrated) means that the drives are not braked to zero speed, but coast to a stop

(this may take some time depending on the level of kinetic energy involved). This

must be included in the protective door locking mechanism logic, e.g. with the logic

operation n < n

Safety Integrated is not capable of detecting parameterization errors made by the

machine manufacturer. The required level of safety can only be assured by

thorough and careful acceptance testing.

The automatic firmware update via p7826 = 1 (upgrade and downgrade) must

never be deactivated under any circumstances when using Safety Integrated.
