H 12 general purpose digital outputs.
4.4.1 Digital inputs - overview
There are a total of 20 general purpose digital inputs. Inputs 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.
Inputs can be shared between axes, and are programmable in Mint (using the keywords
INPUTACTIVELEVEL, INPUTDEBOUNCE, INPUTMODE, INPUTNEGTRIGGER and
INPUTPOSTRIGGER) to determine their active level and if they should be edge triggered. Four
of the inputs, DIN0-DIN3, are fast position latch inputs.
The inputs use two separate common connections. This can be useful for separating inputs
which are active low from others which are active high. If all inputs are similar then the
commons can be connected together to form one common connection. The arrangement of
the inputs, their common power connection and the connectors on which they are available
are described in Table 2 :
