Measures for commissioning
> 1 > 12 > 60
● ● ● Visual inspection of all parts to be
damage-free
● ● ● Resurface the holding brake
● ● Check the electric contacts to verify that
they are free from corrosion
● ● Let the motor run in without load for one
hour at 800 ... 1000 rpm.
● ● Measure insulation resistance. Dry the
winding at a value of < 1kOhm per volt
rated voltage.
● Replace bearings
● Replace encoder

Transport
The motors must be transported in their original
package taking classes 2K11, 2B1, 2C1, 2S5,
2M4 specified acc. to DIN EN 60721-3-2 into
account.
Please observe the following classification limita-
tions:
Table 8:
Classification limitation
(DIN EN IEC 60721-3-2)
Transport
Ambient temperature -25 … +70 °C
Relative humidity 5 … 75 %
Shock load ⮫ Chapter 6.3 “Shock
load during transport und
storage ” on page 32
Remark: Before transport, discharge the liquid
coolant from liquid-cooled motors to avoid frost
damage.
Instructions on transport by air
If motor components with permanent magnets
are shipped by air, the DGR (Dangerous Goods
Regulations) of the IATA (International Air Trans-
port Association) for hazardous materials of class
9 which also include magnetized substances and
objects has to be complied with. This involves,
for example:
•
Secondary parts of synchronous linear
motors
• Rotors of synchronous kit motors
• Rotors of synchronous housing motors (if
these are dispatched as motor component,
i.e. separate from the stator or motor
housing, in service cases)
For details on the maximum allowed magnetic
field strengths as well as information on measure-
ment methods for these magnetic field strengths,
please refer to the current IATA DGR (see chapter
3.9.2.2).

NOTICE
Never touch the connection points of electro-
static sensitive devices!
−
Mounted components (e.g. temperature
sensors, encoder) can contain parts sus-
ceptible to electrical discharge (ESD).
Observe the ESD safety measures.
WARNING
Risk of injury and material damage due to
improper handling during transport!
−
Only use hoisting gear suited for the weight
of the motors. Use lifting sling belts or lifting
eye bolts. Secure the lifting eye bolts before
use.
−
Never walk under hanging loads.
−
Do not lift the motor at the shaft or on the
optional fan housing.
− Use suitable protective equipment and pro-
tective clothing during transport, and wear
safety shoes.
