6.1 Precautions of Operation
WARNING
- Please do not rotate suddenly. Check the direction of rotation at low frequencies. Otherwise, there is a
danger of injury.
- While power is supplied to the inverter, do not touch any terminal or internal part of the inverter, check
signals, or connect or disconnect any wire or connector. Otherwise, you run the risk of electric shock
or fire.
- Be sure to close the top cover before turning on the inverter power. Do not open the top while power is
being supplied to the inverter or voltage remains inside. Otherwise, you run the risk of electric shock.
- Do not operate switches with wet hands. Otherwise, you run the risk of electric shock.
- While power is supplied to the inverter, do not touch the terminal of the inverter, even if it has stopped.
Otherwise, you run the risk of injury or fire.
- If the retry mode has been selected, the inverter will restart suddenly after a break in the tripping
status. Stay away from the machine controlled by the inverter when the inverter is under such
circumstances. (Design the machine so that human safety can be ensured, even when the inverter
restarts suddenly.) Otherwise, you run the risk of injury.
- Do not select the retry mode for controlling an elevating or traveling device because output
free-running status occurs in retry mode. Otherwise, you run the risk of injury or damage to the
machine controlled by the inverter.
- If an operation command has been input to the inverter before a short-term power failure, the inverter
may restart operation after the power recovery. If such a restart may put persons in danger, design a
control circuit that disables the inverter from restarting after power recovery. Otherwise, you run the
risk of injury.
- Prepare the additional emergency stop switch in addition to the stop key of the integrated operator
and/or the optional operator. Otherwise, there is a danger of injury.
- If an operation command has been input to the inverter before the inverter enters alarm status, the
inverter will restart suddenly when the alarm status is reset. Before resetting the alarm status, make
sure that no operation command has been input. Otherwise, there is a danger of injury.
- While power is supplied to the inverter, do not touch any internal part of the inverter or insert a bar in
it. Otherwise, you run the risk of electric shock or fire.
- Run/Stop/Reset is integrated in one button,before you press the button, please make sure that the
machine(facility) Otherwise, you run the risk of injury or damage to the machine controlled by the
inverter.
CAUTION
- Do not touch the heat sink, which heats up during the inverter operation. Otherwise, you run the risk of burn
injury.
- The inverter allows you to easily control the speed of motor or machine operations. Before operating the
inverter, confirm the capacity and ratings of the motor or machine controlled by the inverter. Otherwise, you
run the risk of injury or damage to the machine controlled by the inverter.
- Install an external brake system if needed. Otherwise, you run the risk of injury.
- When using the inverter to operate a standard motor at a frequency of over 60 Hz, check the allowable
motor speeds with the manufacturers of the motor and the machine to be driven and obtain their consent
before starting inverter operation. Otherwise, you run the risk of injury or damage to the motor and machine.
- During inverter operation, check the motor for the direction of rotation, abnormal sound, and vibrations.
Otherwise, you run the risk of injury or damage to the machine driven by the motor.
- Regardless Run command setting(A002/A202) if the key is pressed,inverter starts running. Therefore,if you
selected Run command such as operator or terminal, please handle the key after you made sure that the
machine/facility is operated safety.
