[ 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.
