X7-ANALOG I/O, digital inputs and outputs
It offers 2 inputs and 2 outputs , all of them fully programmable.
Each input and output is associated with a parameter.
See “man_dds_soft.pdf” manual.
It offers a ± 15V power supply for generating a command easily.
Pinout
Analog input 1 Associated with pins 4 and 5. It is the usual input for the velocity com-
mand (± 10 V DC) generated by the CNC.
Analog input 2 Associated with pins 2 and 3. It is the auxiliary command input.
