Instructions on operation
I
WARNING
1. Be sure to put on the surface cover before
turning the power ON (CLOSE).
Never remove the cover while the power is
applied to the inverter.
Otherwise electric shock could occur.
2. Never operate switches with wet fingers.
Otherwise electric shock could occur.
3. The interior of the inverter may remain
charged after turning off the power.
Therefore, never attempt to remove the
surface cover except for wiring service and
periodic maintenance.
Otherwise electric shock could occur.
WARNING
1. When the retry function is selected, the in-
verter may automatically restart after trip-
ping, depending on the cause of the trip.
(Design the machine to secure personal
safety in the event of restart.)
Otherwise accident could occur.
2. Operating conditions may occasionally be
different from the preset acceleration/de-
celeration time or speed because of activa-
tion of the stall prevention function.
In such a case, personal safety must be se-
cured through adequate machine design.
Otherwise accident could occur.
3. The stop key is effective only when a func-
tion setting has been established.
Therefore install an emergency switch in-
dependently. When operation via the ex-
ternal signal terminal is selected, the STOP
key on the keypad panel will be disabled.
There is a risk of accidents.
4. Operation starts suddenly if alarm reset is
done with an running signal input. Check
that no running signal is input before alarm
reset.
Otherwise accidents could occur.
5. Never touch the inverter terminals when
energized even if it has stopped.
Otherwise electric shock could occur.
6. Never touch the keys on the keypad panel
with a pointed object such as a needle.
Otherwise electric shock could occur.
CAUTION
1. Never touch the heat sink because they
become very hot.
Otherwise burns could occur.
2. The inverter can set high-speed operation
easily. Carefully check the limit of the mo-
tor and machine before changing the set-
ting.
Otherwise injuries could occur.
3. Do not use the inverter brake function for
mechanical holding.
Otherwise injuries could occur.
