Digital Inputs
Characteristic
Description
Number of digital inputs
12, divided in 3 groups:
●
DigIn0 ... DigIn3 with DigComm0
●
DigIn4 ... DigIn7 with DigComm1
●
DigIn8 … DigIn11, with DigComm2
Functions of digital inputs DigIn0 ... DigIn11: General Purpose Digital input
●
Position latching
●
Change of state events (1 per MCU’s sample
time)
●
Count transitions (1 per MCU’s sample time)
●
DigIn7 ... DigIn11: can be configured as "disable
drive" input for, respectively, axis0, axis1, axis2,
axis3, axis4. All FETs of an axis are opened to
create an open circuit of motor coils.
The power amplifier is disabled after the disable
drive input is detected active for approximately
500 µs.
