Precautions for Correct Use
• If a power failure has occurred so that the power to the inverter’s control power supply termi-
nals (R0,T0) is lost, and then the inverter is restarted, it is considered as power-on and the
inverter will operate in accordance with the restart after reset [bb-41].
• Even if the power to control power supply terminals (R0, T0) is lost, it will take time until the
internal power supply is completely lost.
• Trip after instantaneous power failure/under-voltage can be switched between “enabled” and
“disabled” by using [bb-27] Selection of instantaneous power failure/under-voltage trip during
stopping. This will prevent the occurrence of an error during stopping. If the error is pre-
vented, the output terminal [AL] will not turn on.
• In a system where the power to control power supply terminals (R0, T0) gradually decreases,
it is possible to cause a trip when Allowable instantaneous power failure time has elapsed.
• To make the power to control power supply terminals (R0, T0) last as much as possible by
the inverter alone during an instantaneous power failure, remove the J51 connector cables
from terminals R0 and T0, and connect a cable from P on the main circuit terminal block to
R0, and N on the main circuit terminal block to T0. Use 0.75 mm
2
or heavier wires for the
connections.
