3.4.4 Multifunction I/O used as pulse inputs
The Multifunction I/O can be set up as pulse inputs, which is necessary to run the MAC
motor in Gear mode or Analogue velocity/gear mode.
When the motor is set to Gear mode, it will follow pulses at the A and B inputs.
2 input formats can be selected.
Pulse and direction.The A input must be applied with the pulses and the B input must be
applied with the direction signal.
Quadrature.Also called encoder format. The pulses at the A and B channel are 90 degree
phase-shifted to determine direction.
The Multifunction I/O's must be set up in MAC-Talk to function as inputs. Also, an input
filter and the preferred direction of movement can be selected.
The pulse inputs are
only used in
and Analogue Velocity/
Gear mode.

See also the descriptions of Gear and Analog Velocity/Gear modes for further details
about functionality.

The pulse input can be set to fast
or slow bandwith which means
2.5MHz or 150kHz. Also, the
direction of movement can be inversed.
