Precautions for Running and Test Running
Otherwise, you run the risk of electric
shock or fire.
While power is supplied to the inverter, do not
touch any internal part or the terminal of the
inverter. Also do not check signals, or
or disconnect any wire or connector.
While power is supplied to the inverter, do not
touch any internal part of the inverter. Also do
not insert a bar in it.
Otherwise, you run the risk of
shock.
Be sure to close the terminal block cover before
turning on the inverter power. Do not open the
terminal block cover while power is being
supplied to the inverter or voltage remains
inside. Do not touch the internal PCB, terminal
block or
connector while power is being
supplied to the inverter or voltage remains
inside.
Do not operate switches in the inverter or on
the board with wet hands.
Otherwise, you run the risk of injury or
fire.
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 and
damage to the machine.
Do not select the retry mode
elevating or traveling device because
free-
running status occurs in retry mode.
If you use the EzSQ program, before operating
the inverter, verify that secure operation of the
program is ensured.
Otherwise, you run the risk of injury and
damage to the machine.
The inverter allows you to easily control the
speed of the motor or machine operations.
Before operating the inverter, confirm the
capacity and ratings of the motor or machine
controlled by the inverter.
When using the inverter to operate a motor at a
high frequency, check the allowable motor
speeds with the manufacturers of the motor and
the machine to be driven and obtain their
cons
ent before starting inverter operation.
During inverter operation, check the motor for
the direction of rotation, abnormal sound, and
vibrations.
