4.4 Digital I/O
There are a total of 20 general purpose digital inputs. Inputs can be configured in MintMT 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.
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 :
