t-monitoring must be used.
Requirements for motor operation with holding brake
●
Ensure the brake functionality during normal operation due to voltage control,
current monitoring, cyclic control of the brake holding torque, for example.
●
Provide an external or an integrated protective circuit within the foreign con-
verter to switch the holding brake (inductive load).
●
Never use the holding brake of the motor as an operating brake.
●
Idle time after an emergency stop before restarting ≥ 3 minutes.
5.4 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 limitations:
Transport
Ambient temperature
-25 … +70 °C
Relative humidity
5 … 75 %
Shock load
see section
chapter 5.6 "Shock load during trans-
Tab. 5-6: Classification limitation (DIN EN IEC 60721-3-2)
Before transport, discharge the liquid coolant from liquid-cooled mo-
tors to avoid frost damage.
Transport by air
If motor components with permanent magnets are shipped by air, the
DGR (Dangerous Goods Regulations) of the IATA (International Air Transport As-
sociation) for hazardous materials of class 9 which also include magnetized sub-
stances and objects must be observed. For example, these regulations are appli-
cable for
●
Secondary parts of synchronous linear motors
●
Rotors of synchronous kit motors
●
Rotors of synchronous housing motors (if shipped as motor components, i.e.,
separated from the stator or motor housing in case service work is required)
For information on the maximum allowed magnetic strenghts and methods of
measuring such magnetic field strengths, please refer to the current IATA DGR
(chapter 3.9.2.2).
