WARNING
Unexpected machine motion immediately after switching on the supply voltage
The Safety Integrated Functions cannot be selected immediately after switching on the supply
voltage. The Safety Integrated Functions can only be selected after the system has completely
run-up. As a consequence, there is an increased risk of an accident while the system runs-up.
Accidents can result in death or severe injuries.
• Close all protective devices before the system runs up.
Persons must not be present in the danger zone.
WARNING
Unsafe operation as encoder monitoring is deactivated
Deactivated or incorrectly parameterized hardware and software monitoring functions of the
encoder can result in unsafe operating states.
• Activate the encoder monitoring functions in the Sensor Module.
• Carefully parameterize the encoder monitoring functions.
• Depending on the fault type and the responding monitoring function, activate stop
function category 0 or 1 according to EN60204-1.
WARNING
Unexpected motor movements due to manipulated connecting cables
The manipulation of the connecting cables can cause unexpected motor movements in a
machine or plant. Particularly in machines or plants in which Safety Integrated Functions are
used to minimize risks, manipulation can result in serious personal injury or death.
• Prevent unauthorized access to the converter, for example by using a lockable control
cabinet.
• Protect the cables inside and outside the control cabinet against manipulation by taking one
of the following measures:
– Sheathe the cables to the motors, encoders and sensors.
– Route the cables in empty conduits.
WARNING
Unexpected machine movement after inserting a memory card
If a memory card without Safety Integrated Functions is inserted instead of a memory card with
active Safety Integrated Functions, when the supply voltage is switched on the next time, the
settings of the Safety Integrated Functions could change, or the Safety Integrated Functions
could be deactivated. Deactivated Safety Integrated Functions or Safety Integrated Functions
that have not been adapted can trigger unexpected machine movements that may result in
serious injury or death.
• Only insert a memory card with the required settings into the drive.
• Prevent unauthorized persons accessing the drive.
• Protect con󹪝gurations with active Safety Integrated Functions against changes by assigning
roles using user management (UMAC).
