FAULT Output

e STR drives feature a digital FAULT output. is output closes

to signal a fault condition.

is output can be used to drive LEDs, relays and the inputs of

other electronic devices like PLCs. e “+” (collector) and “-” (emier) terminals of the output

transistor are available at the connector. is allows you to congure the output for current

sourcing or sinking.

Diagrams of each type of connection follow.

Do not connect the output to more than 30VDC.

e current through the output terminal must not exceed 80 mA.
