Connecting the I/O
Connecting the I/O signal wires into the driver’s I/O terminal blocks (TB3). Screw
terminals are used. Remove the insulation from the core, then insert the core into the
terminal and tighten with terminal screws. Strip 5 mm (0.2 in.) of insulation. Tighten
the terminal screw to the specified tightening torque.
Use a cable of AWG 24 to 20 for the I/O line.
Tightening torque: 0.22 to 0.25 N·m (1.95 to 2.2 lb-in)

6.3 About input/output
Input signals
All input signals of the driver are photocoupler inputs.
The signal state represents the “ON: Carrying current” or “OFF: Not carrying
current” state of the internal photocoupler rather than the voltage level of the signal.
