Warnings for Operations and Monitoring
WARNING: When parameter B_12, level of electronic thermal setting, is
set to device FLA rating (Full Load Ampere nameplate rating), the device
provides solid state motor overload protection at 115% of device FLA or
equivalent. Parameter B_12, level of electronic thermal setting, is a
variable parameter.
.... 3–24
WARNING: Use a disconnect switch or breaker to ensure that you do not
connect the motor or inverter to live wiring. Otherwise, there is the
danger of electric shock.
.... 3–28
CAUTION: Be careful to avoid specifying a braking time that is long
enough to cause motor overheating. If you use DC braking, we recom-
mend using a motor with a built-in thermistor, and wiring it to the
inverter’s thermistor input (see “Thermistor Thermal Protection” on
page 4–20). Also refer to the motor manufacturer’s specifications for
duty-cycle recommendations during DC braking.
.... 3–15
WARNING: Be sure to turn ON the input power supply only after closing
the front case. While being energized, be sure not to open the front case.
Otherwise, there is the danger of electric shock.
...... 4–3
WARNING: Be sure not to operate electrical equipment with wet hands.
Otherwise, there is the danger of electric shock.
...... 4–3
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.
...... 4–3
WARNING: If the Retry Mode is selected, the motor may suddenly
restart after a trip stop. Be sure to stop the inverter before approaching 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.
...... 4–3
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 Run
command 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.
...... 4–3
WARNING: The Stop Key is effective only when the Stop function is
enabled. Be sure to enable the Stop Key separately from the emergency
stop. Otherwise, it may cause injury to personnel.
