3.5 EZF, EZH, EZHD, EZHP synchronous
servo motors
NOTICE
The hollow shaft of the motors moves in relation to the
supply elements passing though during operation.
X
The supply elements must be protected so they do not
scrape against the hollow shaft.
CAUTION!
The hollow shaft can heat up to 100°C in operation.
X
Observe the temperature for the supply elements that
pass through.
3.6 Servo spindle motors EZS/EZM
NOTICE
Destruction of the spindle system!
Removing the spindle shaft from the spindle nut will cause the
system to be destroyed and will void the warranty.
X
Never remove the spindle shaft from the spindle nut!
WARNING!
Risk of injury due to moving parts!
Make certain before commissioning that
X
the spindle shaft and motor are installed in the machine
before you place the drive in operation.
X
no persons will be endangered by the axial movement of
the spindle shaft or slide.
X
no one touches the spindle shaft by coming in physical
contact with it.
WARNING!
Crushing due to contact with the spindle shaft!
Turning the spindle shaft manually with your hand can lead to
crushing injuries.
X
Never turn the spindle shaft manually.
CAUTION!
When EZM synchronous servo motors for screw drives
are in operation the spindle shaft moves axially in
reference to the motor.
X
Fix the spindle shaft in place and install it in the machine.
X
Screw the motor together with the machine or moving
slide.
X
Make certain there are no objects in the axial movement
range of the slide or spindle shaft.

Transport, storage and
preservation
The motors must not be exposed to acceleration levels or
working times of more than 300 m/s² (30 g) as an individual
shock load during transport as per EN 60 068-2-27. The
values for operation apply to long-term shock loads.
When transporting the motors make certain not to damage
the shafts and bearings with impacts.
The motors may only be stored in enclosed, dry rooms.
Storage in open air areas with a roof is only permitted for brief
periods. Protect the motors from all damaging environmental
effects and mechanical damage.
If you will be storing or transporting the system in which a
synchronous servo motor with water cooling is installed below
+3 °C, drain the water completely out of the cooling circuit in
advance.
Avoid extreme temperature fluctuations with high relative
humidity when the motors are being stored temporarily to
prevent formation of water from condensation. If long-term
storage is planned, protect the bare parts of the motor against
corrosion. Before placing a motor in operation again, have the
winding checked for its insulation resistance by an electrical
specialist.
Do not use the fan cover for transport or storage of the
motors. For transport, use the eyebolts on the motors,
together with suitable slings.
Eyebolts are provided only for lifting the motor without
additional attachments. When you remove the eyebolts after
installation, the threaded holes must be permanently closed
corresponding to the protection type of the motors.
