Analog axes.
9.4.2 Configure 2 axes with the same feedback input and analog output.
There are machines having 2 axes that are never in the same configuration at the same time,
because one of them is always parked; for example when changing spindles with an internal
motor used to move its articulation.
In these cases, both motors are controlled by the same servo drive and there is a single
feedback input and a single analog output for the CNC. This way, although the motors are
identical, the axes may be totally different, compensations, dynamics, etc.
Configuring the axes.
To use the same feedback input, parameters COUNTERTYPE and COUNTERID of both
axes must be the same. To use the same analog output, parameter ANAOUTID of both axes
must be identical.
Besides, the motors must necessarily be identical because the following machine
parameters must have the same values for both axes.
The PLC maneuver must include the detection of the active axis and of the parked axis.
