MC2300 Technical Specifications
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 5.1 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
specifications).
For MC2340 all 8 pins are valid. For MC2320 only the first four pins
(axes 1 and 2) are valid.
WARNING! If a valid axis pin is not used, its signal must be
tied high.
Invalid axis pins may be left unconnected.
These pins provide the Index quadrature signals for the incremental
encoders. A valid index pulse is recognized by the chip set when ~Index,
A, and B are all low.
For MC2340 all 4 pins are valid. For MC2320 only ~Index1 and ~Index2
are valid. For MC2310 only ~Index1 is valid.
WARNING! If a valid axis pin is not used, its signal must be
tied high.
Invalid axis pins may be left unconnected.
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.
For MC2340 all 4 pins are valid. For MC2320 only ~Home1 and ~Home2
are valid. For MC2310 only ~Home1 is valid.
WARNING! If a valid axis pin is not used, its signal must be
tied high.
Invalid axis pins may be left unconnected.
All of these pins must be connected to the I/O chip’s digital supply
voltage, which should be in the range 4.75 to 5.25 V.
I/O chip ground. All of these pins must be connected to the digital
power supply return.
These pins may be left unconnected (floating).
