3.6. Opto In Connector (Digital Inputs) (TB305, TB306)
The digital inputs are opto-isolated and may be connected to current sourcing or current sinking devices, as
shown in
and
. These inputs are designed to connect to other ground-referenced
circuits and are not intended for high-voltage isolation.
Port 1 and Port 2 inputs have separate common inputs (refer to
for TB305 and
for
TB306). Each port can be referenced independently.
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.
