OPERATION
WARNING
(Ref. page)
S Only turn ON the inputpower supply after replacing the front cover. Donot
remove the cover while current is flowing.
Failure to observe this warning can result in an electric shock.
38 . . . . . . . . . . . . . . . .
S When the retry function (L5-02) is selected, do not approach the inverter
or the load, since it may restart suddenly after being stopped.
(Construct machine system, so as to assure safety for personnel, even if the
inverter should restart.)
Failure to observe this warning can result in personal injury.
38 . . . . . . . . . . . . . . . . .
S Since the stop button can be disabled by a function setting, install a sepa-
rate emergency stop switch.
Failure to observe this warning can result in personal injury.
38 . . . . . . . . . . . . . . . . .
S If an alarm is reset with the operation signal ON, the inverter restarts auto-
matically. Only reset the alarm after verifying that the operation signal is
OFF.
Failure to observe this warning can result in personal injury.
38 . . . . . . . . . . . . . . . . .
S When adjusting PG zero-pulse, disconnect the motor from the machine.
The motor rotates automatically during adjustment. 49 . . . . . . . . . . . . . . . . . . . .
S When PG zero-pulse adjustment is completed, “End” is displayed on the
digital operator. Do not touch it until it has come to a complete stop.
The motor starts and stops repeatedly when adjustments are made.
49 . . . . . . .
CAUTION
(Ref. page)
S Never touch the heatsink or discharging resistor since the temperature is
very high.
Failure to observe this caution can result in harmful burns to the body.
38 . . . . . . . . .
S Since it is easy to change operation speed from low to high speed, verify
the safe working range of the motor and machine before operation.
Failure to observe this caution can result in personal injury and machine damage.
38 . .
S Install a holding brake separately if necessary.
Always construct the external sequence to confirm that the holding
brake is activated in the event of an emergency, a power failure, or an
abnormality in the inverter occuring.
Failure to observe this caution can result in personal injury.
38 . . . . . . . . . . . . . . . . . .
S If using with an elevator, take safety measures on the machine’s side to
prevent the elevator from dropping.
Failure to observe this caution may result in personal injury.
38 . . . . . . . . . . . . . . . . .
S Do not change signals during operation.
The machine or the inverter may be damaged. 38 . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
