CAUTION: Do not connect 24V signals to the digital inputs.

These unprotected inputs are connected directly to TTL compatible 74AHCT14 devices. If an input is configured as edge triggered, the triggering pulse must have a duration of at least 1ms (one software scan) to guarantee acceptance by MintMT. The use of shielded cable for inputs is recommended.

4.4.1.1General purpose inputs

The general purpose digital inputs DIN0 - DIN19 can be shared between axes, and are programmable in Mint (using a range of keywords beginning with the letters INPUT... ) to determine their active level and if they should be edge triggered. The state of individual inputs can be read directly using the INX keyword. See the MintMT 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 MintMT help file.
