Description

These pins provide the A and B quadrature signals for the incremental

encoder for each axis. When the axis is moving in the positive (forward)

direction, signal A leads signal B by 90°.

The theoretical maximum encoder pulse rate is 10.2 MHz. Actual

maximum rate will vary, depending on signal noise.

NOTE: Many encoders require a pull-up resistor on each signal to

establish a proper high signal. Check your encoder’s electrical

specification.

The number of available axes determines which of these signals are valid.

WARNING! If a valid axis pin is not used, its signal should

be tied high.

Invalid axis pins may be left unconnected or connected to ground.

These pins provide the Index quadrature signals for the incremental

encoders. A valid index pulse is recognized by the chipset when ~Index, A,

and B are all low.

The number of available axes determines which of these signals are valid.

WARNING! If a valid axis pin is not used, its signal should

be tied high.

Invalid axis pins may be left unconnected or connected to ground.

These pins provide the Home signals, general-purpose inputs to the

position-capture mechanism. A valid Home signal is recognized by the

chipset when ~Homen goes low. These signals are similar to ~Index, but are

not gated by the A and B encoder channels.

The number of available axes determines which of these signals are valid.

WARNING! If a valid axis pin is not used, its signal should

be tied high.

Invalid axis pins may be left unconnected or connected to ground.

All of these pins must be connected to the IO chip digital supply voltage,

which should be in the range 3.0 to 3.6 V.

IO chip ground. All of these pins must be connected to the digital power

supply return.

These pins must be left unconnected (floating).
