Configuring procedure
Motion control
Drives are optimized for motion control applications. They execute linear or rotary
movements within a defined 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 "Configuring procedure" is valid for synchronous and induction motors.
General configuring procedure
The function description of the machine provides the basis for configuration. The
components are selected according to physical interdependencies and the selection process
is usually carried out in the following sequence of steps:
Table 5- 2
Configuring sequence
Step
Description of the configuring activity
1.
Clarify the drive type
Refer to the
next chapter
2.
Define the boundary conditions and incorporate them into the automation
system
3.
Define the load case, calculate the maximum load torque and determine the
motor
4.
Define the converter required
Refer to
catalog
5.
Repeat steps 3 and 4 for additional axes
6.
Determine line-side power options (main switch, fuses, line filters, etc.)
7.
Define 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 Mod-
ules)
9.
Determine the connection system components
10.
Configure 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
