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 L3-01 to “0” (overvoltage prevention selection
is disabled). If it is not changed, the inverter may not stop within set decel time.
