Configuration
5.2 Configuring procedure
1FK2 synchronous motors for SINAMICS S120
52 Configuration Manual, 06/2019, A5E46927724B AB
Select the motor on the basis of the required torque (load torque), which is defined by the
application, e.g. traveling drives, hoisting drives, test stands, centrifuges, paper and rolling
mill drives, feed drives or main spindle drives.
Gearboxes to convert motion or to adapt the motor speed and motor torque to the load
conditions must also be taken into account when selecting the motor.
You must know the following mechanical data in order to determine the torque to be supplied
by the motor:
● The load torque specified by the application
● Masses to be moved
● Diameter of the drive wheel
● Leadscrew pitch, gear ratios
● Frictional resistance data
● Mechanical efficiency
● Traversing distances
● Maximum velocity
● Maximum acceleration and maximum deceleration
● Cycle time
Define the boundary conditions and incorporate them into the automation
system
Take the following into account during the configuration:
● The line system configuration when using specific motor types and/or line filters
● Rated values of the motor
● The ambient temperatures and the installation altitude of the motors and drive
components
● Heat dissipation from the motors
Other conditions apply when integrating the drives into an automation environment such as
SIMATIC 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.
