Description
On the MC2340 chipset, this pin is the positive-side (forward) travel limit switch
for axis#3. On the MC2320 and MC2310 chipsets this pin is not used.
On the MC23x3 chipset, this pin is the synchronization signal. In the disabled
mode, the pin is configured as an input and is not used. In the master mode, the
pin outputs a synchronization pulse that can be used by slave nodes or other
devices to synchronize with the internal chip cycle of the master node. In the
slave mode, the pin is configured as an input and a pulse on the pin synchronizes
the internal chip cycle.
WARNING! If a valid axis limit pin is not used, its signal should
be tied high.
On the MC23x0 chipset, this pin is not used.
On the MC2343 chipset, this pin is the positive-side (forward) travel limit switch
for axis#3. On the MC2323 and MC2313 chipsets this pin is not used.
WARNING! If a valid axis limit pin is not used, its signal should
be tied high.
These signals provide inputs from the negative-side (reverse) travel limit
switches. On power-up or Reset these signals default to active low interpretation,
but the interpretation can be set explicitly using the
For MC2340 all 4 pins are valid. For MC2320 only NegLim1 and NegLim2 are
valid. For MC2310 only NegLim1 is valid.
WARNING! If a valid axis pin is not used, its signal must be tied
high. NegLim1 is an output during device reset and as such any
connection to GND or V
Invalid axis pins may also be left unconnected.
Each of these pins can be conditioned to track the state of any bit in the Status
registers associated with its axis.
For MC2340 all 4 pins are valid. For MC2320 only AxisOut1 and AxisOut2 are
valid. For MC2310 only AxisOut1 is valid.
Invalid or unused pins may be left unconnected.
These are general-purpose programmable inputs. They may be used as a
breakpoint input, to stop a motion axis, or to cause an UPDATE to occur.
For MC2340 all 4 pins are valid. For MC2320 only AxisIn1 and AxisIn2 are valid.
For MC2310 only AxisIn1 is valid.
Invalid or unused pins may be left unconnected.
Hall sensor inputs. Each set (A, B, and C) of signals encodes 6 valid states as
follows: A on, A and B on, B on, B and C on, C on, C and A on. A sensor is
defined as being on when its signal is high.
Note: These signals should only be connected to Hall sensors that are mounted
at a 120° offset. Schemes which provide Hall signals 60° apart will not work.
For MC2340 all 12 pins are valid. For MC2320 only the first six pins (axes 1 and
2) are valid. For MC2310 only the first three pins (axis 1) are valid.
Invalid or unused pins may be left unconnected.
