• The key on the keypad is effective only when the keypad operation is enabled with function code F02 (= 0, 2 or 3). When
the keypad operation is disabled, prepare an emergency stop switch separately for safe operations.
Switching the run command source from keypad (local) to external equipment (remote) by turning ON the "Enable
communications link" command LE disables the
key. To enable the key for an emergency stop, select the STOP key
priority with function code H96 (= 1 or 3).
• If an alarm reset is made with the Run command signal turned ON, the inverter may start immediately. Ensure that the Run
command signal is turned OFF in advance.
Otherwise an accident could occur.
• If you enable the "Restart mode after momentary power failure" (Function code F14 = 4 or 5), then the inverter automatically
restarts running the motor when the power is recovered.
(Design the machinery or equipment so that human safety is ensured after restarting.)
• Ensure you have read and understood the manual before programming the inverter, incorrect parameter settings may cause
damage to the motor or machinery.
An accident or injuries could occur.
• Do not touch the inverter terminals while the power is applied to the inverter even if the inverter is in stop mode.
Doing so could cause electric shock.
• Do not turn the main circuit power (circuit breaker) ON or OFF in order to start or stop inverter operation.
Doing so could cause failure.
• Do not touch the heat sink and braking resistor because they become very hot.
Doing so could cause burns.
• Before setting the speeds (frequency) of the inverter, check the specifications of the machinery.
• The brake function of the inverter does not provide mechanical holding means.
Injuries could occur.
Maintenance and inspection, and parts replacement
• Turn the power OFF and wait for at least five minutes before starting inspection. Further, check that the LED monitor is unlit
and that the DC link bus voltage between the P (+) and N (-) terminals is lower than 25 VDC.
Otherwise, electric shock could occur.
• Maintenance, inspection, and parts replacement should be made only by qualified persons.
• Take off the watch, rings and other metallic objects before starting work.
• Use insulated tools.
Otherwise, electric shock or injuries could occur.
Disposal
• Treat the inverter as an industrial waste when disposing of it.
Otherwise injuries could occur.
Others
• Never attempt to modify the inverter.
Doing so could cause electric shock or injuries.
