5.2 Conguring procedure
Motion Control
Drives are optimized for motion control applications. They execute linear or rotary movements
within a dened movement cycle. All movements should be optimized in terms of time.
As a result, drives must meet the following requirements:
• High dynamic response, i.e. short rise times
• Capable of overload, i.e. a high reserve for accelerating
• Wide control range, i.e. high resolution for precise positioning.
The following table "Conguring procedure" is valid for synchronous and induction motors.
General conguring procedure
The function description of the machine provides the basis for conguration. The components
are selected according to physical interdependencies and the selection process is usually carried
out in the following sequence of steps:
Table 5-1 Conguration sequence
step Description of the conguring activity
1. Clarify the drive type See the next
chapter
2. Dene the constraints and incorporate them into the automation system
3. Dene the load case, calculate the maximum load torque and determine the
motor
4. Dene the converter required See
catalog
5. Repeat steps 3 and 4 for additional axes
6. Determine line-side power options (main switch, fuses, line lters, etc.)
7. Dene other system components (e.g. braking resistors)
8. Calculate the current demand of the components for the 24 V DC power supply
- and specify the power supplies (SITOP devices, Control Supply Modules)
9. Determine the connection system components
10. Congure the drive line-up components
11. Calculate the required cable cross sections for power supply and motor con‐
nections
12. Inclusion of mandatory installation clearances
Observe also the recommended combinations of converters and motors with the associated
connecting cables in the Chapters "Motor overview / Assignment Motor modules / Power cables
(Page 85)".
