Danger!
Danger of injury due to rotating or moving elements and loads!
By rotating or moving elements, body parts can be drawn in or severed or subjected to impacts.
•
Do not stay in the danger zone during operation and secure it against access by unauthorized
persons.
•
Before working on the machine, secure it against unwanted movements. Any holding brake
present is not suitable for this!
•
Keep all covers and control cabinet doors closed during operation and as long as the machine
is not disconnected from the power system.
•
Always operate the motor with all safety equipment. Do this even during short testing and trial
operations!
•
Motors can be started automatically via remote control! If appropriate, a corresponding warning
symbol must be applied, and protective measures must be implemented to prevent entry into
the high-risk area.
Danger!
Danger of injury due to loads!
Suspended loads can lead to personal injury or death if they fall down. Heavy loads can tilt and trap
people or severely injure them.
Failure to comply with instructions, guidelines and regulations or use of unsuitable or damaged tools
and devices can result in serious injury and/or damage to property.
•
Motors should only be lifted without any additional load from other products (e.g. connection
elements).
•
Only use permitted lifting, transport and aids with sufficient lifting capacity.
•
Never stand in the danger zone or under suspended loads.
•
Secure the product against dropping and tilting.
•
Wear safety shoes, protective clothing and a safety helmet.
•
Comply with the national and local regulations.
Warning!
Danger of injury due to incorrect control or a defect.
Improper control of motors or a defect can result in injuries and unintended and hazardous movements
of motors.
Such incorrect behavior can be triggered by:
•
Incorrect installation or faults when handling components
•
Improper or incomplete wiring
•
Defective devices (servo drive, motor, position encoder, cables, brake)
•
Incorrect control (e.g. caused by software error)
Risk due to hot surfaces
Due to the power dissipation from the motor and friction in the gearbox, these components as well as their envi-
ronment can reach a temperature of more than 100°C.
The resulting heat is released to the environment via the housing and the flange.
