C-863 Mercury Controller MS205Equ Version: 2.0.0 3
1.3 Definition
Term Explanation
PC software Software that is installed on the PC.
Firmware Software that is installed on the controller.
Volatile memory RAM module in which the parameters are saved when the controller is switched
on (working memory).
Non-volatile
memory EEPROM memory chip (read-only memory), from which the default values of
the parameters are loaded to the volatile memory when the controller is started.
Axis Also referred to as "logical axis". The logical axis reflects the motion of the stage
in the firmware of the C-863. For stages that allow motion in several directions
(e. g. in X, Y and Z), each direction of motion corresponds to a logical axis.
Stage Mechanical system connected to the C-863. For stages having just one motion
axis the designation "axis" is synonymous with "stage". Stages that allow motion
in several axes are also designated as "multiaxis stages". For these stages, a
distinction must be made between the individual axes.
In this manual, actuators, i. e. drive components without a moving platform (e. g.
precision linear actuators), are designated as stages as well.
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.
Incremental
position sensor Sensor (encoder) for capturing changes of position or changes of angle. Signals
from the incremental position sensor are used for axis position feedback. After
switching on the controller a reference point definition must be performed before
absolute target positions can be commanded and reached.
Control value The control value is the input for the PWM converter of the C-863. The PWM
converter converts the control value into the PWM signal for the stage.
Dynamics profile Comprises the target position, velocity, and acceleration of the axis calculated
by the profile generator of the C-863 for any point in time of the motion. The
calculated values are called "commanded values".
GCS PI General Command Set; command set for PI controllers. Piezo drivers and
servo controllers can be operated conjointly with minimal programming effort
thanks to the GCS.
