* 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.
[
When using the braking resistor unit, set constant L3
−
04 to “0” (stall prevention selection during
decel is disabled). If it is not changed, the inverter may not stop within set decel time.
