Product−specific terms and abbreviations
The following product−specific terms and abbreviations are
used in this manual:
Term/abbreviation Meaning
0−signal 0 V are present at input or output (positive logic, corresponds to LOW).
1−signal 24 V are present at input or output (positive logic, corresponds to HIGH).
Axis zero point (AZ) Measuring reference point for the project zero point and the software end
positions. Corresponds to the project zero point in the SFC−DC−...−IO
(offset = 0). The reference point for the axis zero point is the reference
point.
Axis Complete actuator, consisting of controller, motor, encoder, if applicable,
gear and drive.
Controller Control electronics which evaluate the control signals and provide the
power supply for the motor via the power electronics (power electronics +
controller + position controller).
Drive Mechanical component of an axis which transfers the drive power for the
movement, defines the guide for the positioning movement, and enables
the work load and the reference switch to be fitted.
The electric slide type SLTE is an integrated unit consisting of a motor,
encoder, gear unit and drive.
EMC ElectroMagnetic Compatibility
Encoder With the SLTE: magnetic pulse generator (rotor position transducer). The
electric signals generated are sent to the controller, which then calculates
the position and speed on the basis of the signals received.
Festo Configuration
Tool (FCT) Software with uniform project and data management for all supported
device types. The special wishes of a device type are supported by plug−ins
with the necessary descriptions and dialogues.
