Checking the work performed

Checking the mounting work
After installation has been completed, check that the rotor can freely rotate. Note that with
short-circuited motor phases, the rotor is difficult to turn – even if no mechanical resistance is
otherwise present.
Before moving the rotor, remove all tools and objects from the area of the rotor and air gap.
Risk of electric shock
A voltage is induced in the stator when the rotor rotates. You can get an electric shock
when touching the terminals, the open cable ends or the plug connector contacts.
•
• The mounted rotary axes must always be able to move without hindrance.
Examples of axes that cannot necessarily be checked by hand:
– Large axes with a high friction torque
– Blocking in a current-free state
– Uneven weight forces
• All cables must be routed and secured in such a way that they cannot be bent, pressed
against rotating parts or damaged in any other way.
• Coolant supply ducts must be easily accessible and the coolant must be allowed to flow
freely.

WARNING
Correctly connect the motor power cables.
Alternatively:
Insulate the plug connector contacts or terminals and conductors of open cable ends
before you rotate the rotor.
WARNING
Danger if an axis moves in an uncontrolled manner.
There is a risk that the axis moves in an uncontrolled fashion if you release the
locking or brake when the axis is de-energized and not subject to closed-loop control.
• Carefully ensure that nobody is in the hazard zone.
