@ WARNING
GREAT MASS OR FALLING PARTS
• Consider the mass of the axis when mounting it. It may be neces-
sary to use a crane.
• Mount the axis in such a way (tightening torque, securing screws)
that the axis and mounted parts cannot come loose even in the
case of fast acceleration or continuous vibration.
• Note that vertically installed linear axes may lower unexpectedly.
Failure to follow these instructions can result in death, serious
injury or equipment damage.
@ WARNING
MOTOR WITHOUT BRAKING EFFECT
If power outage and faults cause the power stage to be switched off,
the motor is no longer stopped by the brake and may increase its
speed even more until it reaches a mechanical stop.
• Verify the mechanical situation.
• If necessary, use a cushioned mechanical stop or a suitable hold-
ing brake.
Failure to follow these instructions can result in death, serious
injury or equipment damage.
@ CAUTION
HOT SURFACES
Depending on the operation, the surface may heat up to more than
100°C (212°F).
• Do not allow contact with the hot surfaces.
• Do not allow flammable or heat-sensitive parts in the immediate
vicinity.
• Consider the measures for heat dissipation described.
• Check the temperature during test runs.
Failure to follow these instructions can result in injury or equip-
ment damage.
