8 Commissioning the safety technology
8.1 Safety instruction
Dangerous movements! Danger to life, risk of
injury, serious injury or property damage!
WARNING
Do not commission the system without having it checked by a qualified
individual!
Before a system with integrated safety technology is commissioned for the
first time, the system must be checked and approved in documented form by
a qualified individual.
Check the danger zone!
● Before commissioning, make sure that nobody is staying in the danger
zone.
● Check the danger zone and secure it against access by individuals
(e.g., put up warning signs, install barriers or the like).
Observe the applicable laws and local regulations.
8.2 Prerequisites for using integrated safety technology
8.2.1 General information
The mechanical parts of power transmission, such as gearbox, motor, and
those of the safety devices (brakes, fall-down protection, arresting device, ...)
shall be designed to withstand the occurring static and dynamic stresses
(e.g., dual load due to weight).
The safety factor and the sizing are application-specific and have to be
defined by the plant or machine manufacturer.
For the maximum gearbox input torque, too, a safety factor in relation to the
maximum motor torque has to be taken into account. This also applies to
motor-gearbox combinations by Bosch Rexroth. (See also documentation of
the respective gearbox.)
In the case of error, injury and property
damage due to inadmissibly high voltage!
WARNING
For selection and the 24 V supply of devices with integrated safety
technology, use a 24 V power supply unit with protection by SELV
1)
in
accordance with IEC 60950‑1 or PELV
2)
in accordance with IEC 60204‑1.
8.2.2 Required drive firmware
The safety technology function made available by the "T option" is a
functionality only scalable using the hardware. This safety technology
function does not require any additional enabling of functional firmware
packages.
The integrated safety function can be used with the firmware version
FWA‑XD1‑AXS‑V‑01xxx‑xx and above.
