2.5.4. Digital Inputs 0-3 (J205)î
The digital inputs are opto-isolated and may be connected to current sourcing or current sinking devices, as
shown in Figure 2-30 and Figure 2-31. These inputs are designed to connect to other ground-referenced
circuits and are not intended for high-voltage isolation.
The opto-isolator's common connections can be directly connected to the drive's power supply; however,
doing so will effectively defeat the isolation and will reduce noise immunity.
