2.5.3. Opto-Isolated Outputs (J104)
The digital outputs are optically-isolated and may be connected in sourcing or sinking configurations. The
digital outputs are designed to connect to other ground referenced circuits and are not intended to provide
high-voltage isolation.
The outputs are software-configurable and must be connected in either all sinking or all sourcing mode.
Figure 2-36
and
Figure 2-37
illustrate how to connect to an output in current sourcing and current sinking
modes.
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.
