2.5.4. Opto-Isolated Inputs (J104)
The digital inputs are opto-isolated and may be connected to current sourcing or current sinking devices, as
shown in
Figure 2-38
and
Figure 2-39
. 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.
