Digital inputs DIN0 to DIN3 have a common specification:

H Opto-isolated high-speed digital inputs.

H Sampling frequency 1 kHz.

Note: Digital inputs DIN0 to DIN3 are particularly sensitive to noise, so inputs must use

shielded twisted pair cable.

Digital inputs DIN0 to DIN3 can be used as high speed position latches. A fast position input

can cause the position of any combination of axes to be captured (by the hardware) within

1 μs. Special Mint keywords (beginning with the letters FAST...) allow specific functions to be

performed as a result of fast position inputs becoming active.

Active high: The high speed digital inputs will be active when a voltage of +24 VDC (±20%) is

applied to them and will sink a maximum of 7 mA each.

Active low: The digital inputs will be active when grounded (< 2 V) and will source a

maximum of 7 mA each.

Note: Sustained input voltages above 30 V will damage the inputs.
