3.3.1.2 Specification of the supplementary conditions and integration into the automation system
Take the following into account during the confguration:
● The line system configuration when using specific motor types and/or line filters
● The utilization of the motor rated values for winding overtemperatures of 60 K or 100 K (for
synchronous motors)
● The ambient temperatures and the installation altitude of the motors and drive components
● The heat dissipation from the motors through natural ventilation, forced ventilation or water
cooling
Other conditions apply when integrating the drives into an automation environment such as
SINUMERIK or SIMOTION.
For motion control and technology functions (e.g. positioning), as well as for synchronous
operation functions, the corresponding automation system, e.g. SIMATIC S7-1500 or
SIMOTION D is used.
3.3.1.3 Definition of the load, calculation of the maximum load torque and determination of the
motor
The motors are defined bases on the motor type-specific limiting characteristic curves.
The limiting characteristic curves describe the torque or power curve over the speed.
The limiting characteristic curves take the limits of the motor into account on the basis of the
DC-link voltage. The DC-link voltage is dependent on the line voltage.
In the case of torque drive the DC-link voltage is dependent on the type of Line Module and
the type of infeed module or infeed/regenerative feedback module.
