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.
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.
Warning!
Risk of burns due to hot surfaces!
Touching hot surfaces (e.g. motor and gearbox housings, as well as connected components), can lead
to very severe burns due to the very high temperature of these parts.
•
Do not stay in the danger zone during operation and secure it against access by unauthorized
persons.
•
Never touch the motor or gearbox housing as well as adjacent surfaces during nominal load
operation.
•
Be aware of hot surfaces also during downtime.
•
Allow motor and gearbox to cool sufficiently before working on it. This is because there is still
a risk of burning for a prolonged period of time even after shutting down.
•
Always operate the motor or gearbox with all safety devices. Do this even during short testing
and trial operations!
