General configuring procedure
The function description of the machine provides the basis for configuring the drive
application. The components are selected according to physical interdependencies and the
selection process is usually carried out in the following sequence of steps:
Step
Configuration activity description
1.
Clarification of the drive type
2.
Definition of supplementary conditions and integration into an automation system
3.
Definition of the load, calculation of the maximum load torque, and selection of the motor
4.
Selection of SINAMICS S120 Motor Modules in booksize format/SINAMICS S120 Combi Power
Modules
5.
Repetition of steps 3 and 4 for additional axes
6.
Calculation of the required DC link power and selection of the SINAMICS Line Module (for
SINAMICS S120 Motor Modules in booksize format only)
7.
Selection of the line-side options (for example, main switch, fuses, and line filters)
8.
Specification of the required control performance, selection of the Control Unit, and definition
of component cabling (for SINAMICS S120 Motor Modules in booksize format only)
9.
Definition of other system components (for example, braking resistors)
10.
Calculation of the current demand of the 24 V DC supply for the components and specifica-
tion of the power supplies (for example, SITOP devices and Control Supply Modules)
11.
Selection of the components for the connection system
12.
Configuration of the drive line-up components
13.
Calculation of the required cable cross sections for power supply and motor connection
14.
Inclusion of mandatory installation clearances
Clarification of the type of drive
The motor is selected on the basis of the required torque, which is defined by the application,
for example, traveling drives, hoisting drives, test stands, centrifuges, paper and rolling mill
drives, feed drives, or main spindle drives. Gearboxes used to convert motion or to adapt the
motor speed and motor torque according to the load conditions must also be considered.
In addition to the load torque that is determined by the application, the following mechanical
data is among those required for the calculation of the torque to be provided by the motor:
• Mass to be moved
• Diameter of the drive wheel
• Leadscrew pitch and gear ratio
• Frictional resistance
• Mechanical efficiency
• Traversing path
• Maximum velocity
• Maximum acceleration and maximum deceleration
• Cycle time
