Absolute value encoder
Position encoder which outputs the position in the form of a digital numerical value. This
numerical value is unique within the entire resolution range of the absolute value encoder.
Axis control panel
The axis control panel allows you to move the axis in manual mode, optimize the axis
settings, and test the operation of the axis in your system.
Axis type
The axis type differs depending on the unit of measurement according to which the axis is
positioned.
Depending on the execution of the mechanics, an axis is implemented as a linear axis or
rotary axis:
● For linear axes, the position of the axis is specified as a linear measure,
● For rotary axes, the position of the axis is specified as an angular measure,
Communication processor (CP)
Module for expanded communications tasks covering special applications, for example in the
area of security.
Communications module (CM)
Module for communications tasks which is used as an interface expansion of the CPU
(for example PROFIBUS) or provides additional communications options (e.g. PtP) in an
automation system.
Drive
The combination of motor (electric or hydraulic), actuator (converter, valve), control system,
measuring system and supply (infeed, accumulator).
Dynamic Servo Control (DSC)
In drives that support DSC, you can optionally use the position controller in the drive. The
position controller in the drive is usually implemented with a rapid speed-control cycle. This
improves the control performance for digitally coupled drives.
