Safety instructions

WARNING

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 may not be in the hazardous area.

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 "Acceptance test").

Before persons 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 during switch-on:

The safety-related functions are only available and can be activated after the system has completely started up.

WARNING

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 SSM (n<nx).

WARNING

Safety Integrated is not capable of detecting parameterization errors made by the machine manufacturer. The required level of safety can only be assured by careful acceptance testing.

WARNING

The automatic FW update via p7826 = 1 (upgrade and downgrade), which is available from version V2.5, must not be deactivated when Safety Integrated is used.

CAUTION

If two power transistors in the power unit (one in the upper and one offset in the lower inverter bridge) fail at the same time, this can cause a momentary movement.

The maximum movement can be:

Synchronous rotary motors: Max. movement = 180 ° / pole pair count Synchronous linear motors: Max. movement = pole width
