Warning Messages for Operating Procedures
WARNING: Be sure to turn on the input power supply after closing the front case.
While being energized, be sure not to open the front case. Otherwise, there is the danger
of electric shock.
WARNING: Be sure not to operate the switches with wet hands. Otherwise, there is the
danger of electric shock.
WARNING: While the inverter is energized, be sure not to touch the inverter terminals
even when the motor is stopped. Otherwise, there is the danger of electric shock.
WARNING: If the Retry Mode is selected, the motor may suddenly restart during the
trip stop. Do not approach the machine (be sure to design the machine so that safety for
personnel is secure even if it restarts.) Otherwise, it may cause injury to personnel.
WARNING: If the power supply is cut off for a short period of time, the inverter may
restart operation after the power supply recovers if the command to operate is active. If a
restart may pose danger to personnel, so be sure to use a lock-out circuit so that it will
not restart after power recovery. Otherwise, it may cause injury to personnel.
WARNING: The Stop Key is effective only when the Stop function is enabled. Be sure
to enable the Key separately from the emergency stop. Otherwise, it may cause injury to
personnel.
WARNING: After the operation command is given, if the alarm reset is conducted, it
will restart suddenly. Be sure to set the alarm reset after verifying the operation
command is off. Otherwise, it may cause injury to personnel.
WARNING: Be sure not to touch the inside of the energized inverter or to put any
conductive object into it. Otherwise, there is a danger of electric shock and/or fire.
WARNING: When the power is turned on when the running command is already active,
the motor will suddenly start rotation and is dangerous. Before turning the power on,
confirm that the running command is not enabled.
WARNING: When the Stop key function is disabled, pressing the Stop key does not
cancel the stop and trip.
WARNING: Be sure to provide a separate, hard-wired emergency stop switch. When
the operation command source is a digital operator, this selection is ineffective.
