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:
Hforward limit (end of travel) input on any axis
Hreverse limit (end of travel) input on any axis
Hhome input on any axis
Hdrive error input on any axis
Hcontrolled 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
