Danger to life as a result of a malfunction due to an acceptance t est t hat has not been
c arried out after changes to parameters have been made
Safety Integrated functions cannot detect parameter changes made by the machine builder
(OEM). Incorrect parameter changes for SI functions can result in accidents leading to
death or severe injury.
• After making a change to a parameter, always carry out an acceptance test and
• Only use the system or machine after the acceptance test has been successfully
Danger to life as a result of different responses of the S afety Integrated f unctions when
replacing a Motor Module or a motor
Motor Modules or the motor must be replaced with a device of the same type, as the
parameter settings will otherwise lead to an incorrect response of the Safety Integrated
functions. Functionality that has been modified can result in accidents leading to death or
severe injury.
• Always replace a component by an identical component of precisely the same type.
• Readjust the drive involved when replacing an encoder.
• Carefully test the functionality after replacement.
Danger to life as a result of parameterized safety functions, which are only available t o a
res tricted extent, when an internal or external f ault occurs
If an internal or external fault occurs, none or only some of the parameterized safety
functions are available during the STOP F response triggered by the fault.
• Carefully take this into account when parameterizing a delay time between STOP F and
P arameterizing the encoder system
Encoder faults are detected using different hardware and software monitoring functions.
• It is not permissible to disable these monitoring functions (i.e. the encoder monitoring in

the Sensor Module) and they must be parameterized carefully. Depending on the fault
type and the responding monitoring function, stop function category 0 or 1 in
accordance with EN 60204-1 (fault response functions STOP A or STOP B to Safety
Integrated) is selected (see table "Overview of stop responses" in Section "Safety
Integrated Extended Functions", in the section "Safety faults").
