• 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.)
• If you set the function codes wrongly or without completely understanding this instruction
manual, the motor may rotate with a torque or at a speed not permitted for the machine.
An accident or injuries could occur.
• Do not touch the inverter terminals while the power is applied to the inverter even if the
inverter stops.
Doing so could cause electric shock.
• Do not turn the main circuit power on or off in order to start or stop inverter operation.
Doing so could cause failure.
• Do not touch the heat sink or braking resistor because they become very hot.
Doing so could cause burns.
• Setting the inverter to high speeds is easy. Before changing the frequency (speed) setting,
check the specifications of the motor and 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.
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 matter before starting work.
• Use insulated tools.
Otherwise, electric shock or injuries could occur.
