3.4 User I/O
3.4.6 Multifunction I/O used as pulse outputs
The Multifunction I/O can be set up as pulse outputs. When this configuration is selected,
the internal encoder signal will be available at the outputs.
This can be useful in modes in which the internal encoder signal must be used as feed-
back to external electronics for monitoring the real-time position, or as a part of a closed-
loop regulation.
This feature is especially relevant in the following 4 modes: Velocity, Position, Analogue
Torque and Analogue Velocity.
A quadrature signal will appear at the A and B channel. Quadrature means that the two
channels are 90 degree phase shifted either positively or negatively, which determines
the actual direction of movement of the motor.
The Multifunction I/O’s must be set up in MAC-Talk to function as pulse outputs.
See also the respective mode descriptions for further details about functionality.
