Input / Output 4-7MN1904
4.6 Digital I/O
There are a total of 20 digital inputs. Inputs DIN0 to DIN15 are general purpose inputs, which
can be configured in Mint for any of the following functions:
H forward limit (end of travel) input on any axis
H reverse limit (end of travel) input on any axis
H home input on any axis
H drive error input on any axis
H controlled stop input on any axis.
Inputs DIN16 to DIN19 are known as fast position interrrupts and can only be used to latch
position. They cannot be used as general purpose inputs and their states cannot be read in
Mint.
Inputs can be shared between axes, and are programmable in Mint (using the keywords
INPUTACTIVELEVEL, INPUTMODE, INPUTPOSTRIGGER and INPUTNEGTRIGGER)to
determine their active level and if they should be edge triggered.
There are a 8 general purpose digital outputs. An output can be configured in Mint as a
general purpose output, a drive enable output or a general error output. Outputs can be shared
between axes and are programmable, using the Mint keyword OUTPUTACTIVELEVEL,to
determine their active level.
The outputs are driven by a current sourcing, PNP Darlington type driver , with overcurrent and
short circuit protection. Power for the outputs is derived from a customer supplied 12-24V
supply.
