Thisallows each group to be configured independently for ëactive highí or ëactive lowí operation (usingthe Mint INPUTMODE keyword).The general purpose digital inputs DIN0 - DIN19 can be shared between axes, and areprogrammable in Mint (using a range of keywords beginning with the letters INPUT... ) todetermine their active level and if they should be edge triggered. The state of individual inputs canbe read directly using the INX and INSTATEX keywords. See the Mint help file.A general purpose digital input can be assigned to a special purpose function such as a home,limit, stop or error input. See the keywords HOMEINPUT, LIMITFORWARDINPUT,LIMITREVERSEINPUT, STOPINPUT and ERRORINPUT in the Mint help file.4.3.1.1 DIN0 - DIN3Digital inputs DIN0 to DIN3 can be assigned as fast interrupts. These are used as high speedposition latches, allowing any combination of axes to be captured by the hardware. The latencybetween input triggering and capture is 1 μs. Special Mint keywords (beginning with the lettersLATCH...) allow specific functions to be performed as a result of fast position inputs becomingactive. See the Mint help file for details.DIN36k2TLP115ADGNDMintVccNextMove e100CREF0100R13Shield 2ëX10íFigure 8 - Fast interrupt digital input - DIN3 shownDigital inputs DIN0 to DIN3 use CREF0 as their common connection.Note: The fast inputs are particularly sensitive to noise, so inputs must use shieldedtwisted pair cable. Do not connect mechanical switches, relay contacts or othersources liable to signal ëbounceí directly to the fast inputs. This could causeunwanted multiple triggering.
