Virtual Axes The MC Unit contains a total of 3 axes, of which two can be configured as vir-
tual axis. The virtual axes are internal axes and are used for computational
purposes. They act as perfect servo axes and are very useful for creating pro-
files. They can be linked directly to the servo axes.
Hardware-based
Registration Inputs
There is a high-speed registration input for the encoder input and output axis.
On the rising or falling edge of a registration input, the MC Unit will store the
current position in a register. The registered position can then be used by the
BASIC program as required. The registered positions are captured in hard-
ware.
General-purpose Input
and Output Signals
Starting, stopping, limit switching, origin searches and many other functions
can be controlled by the MC Unit. The general I/O can have specific functions
(such as the registration, limit switches), but also can be freely used.
Reduced Machine Wear The traditional trapezoidal speed profile is provided to generate smooth start-
ing and stopping. The trapezoidal corners can be rounded off to S-curves.
