Introduction
The integrated safety technology "SafeMotion" is a dual-channel system in
which two processors redundantly carry out the safety-related monitoring func-
tions and monitor each other with regard to validation and correctness. When
a processor detects a problem or the cross data comparison is inconsistent,
the axis is safely decelerated. The behavior of the safety technology is based
on the configuration of the scaling and encoder settings, as well as on the
parameterization of the safety functions.
After the machine acceptance test has been successfully carried out, the safety
technology parameters must not be changed any more.
All safety technology parameters must be verified by the user during parameter-
ization.
Changes in the encoder and scaling settings (configuration parameters) require
that the axis be validated again and the machine acceptance test be repeated.
Changes in the safety technology parameterization require that the machine
acceptance test be repeated.
To commission the safety technology, always use the current release of the
corresponding firmware version as well as the ctrlX DRIVE Engineering commis-
sioning software.
Take the corresponding manufacturer information on detected and solved prob-
lems into account and verify their relevance for the machine application.
For information about the current release version and the manufacturer
information, refer to the "eBusiness Portal" under

Prerequisites for using integrated safety technology
General information
The ctrlX DRIVE system (axis / spindle / roll) consists of the components con-
trol section, power section and motor. The control section is integrated in the
power section.
By the interaction of hardware and software components, ctrlX DRIVE provides
the Integrated Safety Technology.
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.
Required drive firmware
The integrated safety functions can be used with the following firmware ver-
sions:
R911404905, Edition 02
In case of error, personal injury and material damages
WARNING
possible due to impermissibly high voltage!
For the selection and the 24 V supply of devices with
integrated safety technology, use a 24V power supply
unit protected by SELV in accordance with IEC 60950‑1
or PELV in accordance with IEC 60204‑1.
