6.3 Configuration of Axes
Overview of the types of axes supported by the MANUALplus 620:
Digital axes (not MC 320(T)):
Closed-loop axes with encoder; controlled by a controller unit (CC)
Analog axes:
Closed-loop and open-loop axes with and without encoder; with analog
output of nominal value
Manual axes:
Axes with encoder but without motor; these axes can be programmed and
are taken into account in the kinematics (e.g. manually operated axes with
mechanical handwheels)
Display axes:
Axes with encoder but without motor; these axes cannot be programmed,
and are not taken into account in the kinematics
Virtual axes:
Axes with neither an encoder nor a motor; however, their nominal values are
added to real axes (non-circular grinding)
PLC axes:
Axes that are controlled by the PLC run-time system, e.g. magazine axes or
spindles with coded spindle speed output.
