Components of a Position Control System

The IP 266's position controller enables precise positioning of the drive. The
following components are required for a position control system:
Mains
power
Safety device
Speed controller
with static
converter

Power section
Figure 4-4. Components of a Position Control System
• Power section
The power section is driven via the IP 266's analog output, and comprises
rotational speed controller and static converter.
• Motor
The power section drives the motor in accordance with the directives from
the IP 266.
• Mechanical transmission elements
In addition to the axis, the mechanical transmission elements include gears
and coupling systems.
• Position measuring system
The position measuring system measures movement. An incremental position
encoder supplies the IP 266 with pulses. The number of pulses is proportional
to the path travelled.
