Multi-axis management.
Configuring the external feedback (direct feedback).
Type of feedback input for the axis.
The internal feedback (motor) of both axes is located at the drive. Parameter
COUNTERTYPE indicates the location of the external (direct) feedback of the axis; at the
remotte modules (4 inputs per module, differential TTL, 1 Vpp sinusoidal), at the free input
of a Sercos drive or at the local feedback inputs of the central unit (2 TTL and differential
TTL inputs).
When using a Sercos drive, the axis can use the second free feedback input of that drive
or of another one. When the axis uses the second feedback input of another drive, the CNC
does not allow homing the axis; therefore, the axis must have absolute feedback.
Parameter. Meaning.
COUNTERTYPE Type of feedback input for the axis; drive, local or remote.
COUNTERID Number of the feedback input for the axis.
When the internal (motor) feedback and the external (direct) feedback of an axis are at different drives,
set parameter PP5=-0,0001 at the drive that receives the external feedback.
