Safety notices
System power-up and drive activation after changing or replacing hardware and/or software
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. It is not permissible that personnel are 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.
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).
Drive coasts down with STO or STOP A
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 interlocking logic, e.g. with the logic operation n < n
No detection of parameter assignment errors by Safety Integrated Functions
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.
Firmware update via p7826 = 1
The automatic firmware update via p7826 = 1 (upgrade and downgrade) must never be
deactivated under any circumstances when using Safety Integrated.
