If optocoupling is activated, pin 20 to pin 29 are not tied to the internal
ground and must be tied to the ground of the ex12 V power supply.
Needs factory service to be activated.
Logical Inputs
1)
Optoisolated logical inputs:
These inputs works with current driven into the led. I f there is no current,
input is read as a I, i f there is current through the LED, input is read as a 0.
To drive current through the LED, you can tie the input to ground or drive it
by an open collector. This way, the logic level seen at the input, is the
same as the one given by the KB command.
To ensure good performances, when current is present its value must be
between 5mA and 10 mA.
l b be taken into account, one pulse on the input must be larger than one
servo-cycle.
Logical Outputs
2-) T h e minimum width on an output pulse cannot be smaller than one servo-
cycle.
To assure good use and performances of the MM4006, respect these maxi-
mum ratings.
