When using the braking resistor unit, set constant L3-01 to “0” (overvoltage prevention selection

is disabled). If it is not changed, the inverter may not stop within set decel time.

Use sequencer to break

power supply side on

overload relay trip contact

of braking resistor unit.

:

When installing a DC reactor (option), remove the common bar between ¨1 and ¨2 terminals

(provided as standard) and connect a DC reactor with the terminals.
