Explanation
Axis
Also referred to as "logical axis". The logical axis represents the motion
of the mechanics in the firmware of the C-863.12. For mechanics that
allow motion in several directions (e.g., in X, Y, and Z), each direction of
motion corresponds to a logical axis.
Daisy chain
Wiring diagram by which one controller is connected to the next in
sequence (series connection principle). Here the first controller is
connected directly to the PC. The additional controllers are always
connected to the ones that precede them so that a chain is formed.
The signal to and from a controller goes to the PC via the previous
controllers.
Dynamics profile
Comprises the target position, velocity, and acceleration of the axis
calculated by the profile generator of the C-863.12 for any point in
time of the motion. The calculated values are called "commanded
values".
Firmware
Software that is installed on the controller.
Volatile memory
RAM module where the parameters are saved when the controller is
switched on (working memory). The parameter values in the volatile
memory determine the current behavior of the system.
The parameter values in the volatile memory are also referred to as
"Active Values" in the PC software from PI.
GCS
PI General Command Set; command set for PI controllers. Piezo drivers
and servo controllers can be operated together with minimal
programming effort thanks to GCS.
Incremental position
sensor
Sensor (encoder) for detecting changes of position or changes of angle.
Signals from the incremental position sensor are used for axis position
