Operation and Adjustment Precautions
Turn ON the input power supply only after mounting the front cover, terminal
covers, bottom cover, Operator, and optional items. Not doing so may result in
electrical shock.
Do not remove the front cover, terminal covers, bottom cover, Operator, or
optional items while the power is being supplied. Doing so may result in
electrical shock or damage to the product.
Do not operate the Operator or switches with wet hands. Doing so may result
in electrical shock.
Do not touch the inside of the Inverter. Doing so may result in electrical shock.
Do not come close to the machine when using the error retry function
because the machine may abruptly start when stopped by an alarm. Doing so
may result in injury.
Do not come close to the machine immediately after resetting momentary
power interruption to avoid an unexpected restart (if operation is set to be
continued in the processing selection function after momentary power
interruption is reset). Doing so may result in injury.
Provide a separate emergency stop switch because the STOP Key on the
Operator is valid only when function settings are performed. Not doing so may
result in injury.
Be sure to confirm that the RUN signal is turned OFF before turning ON the
power supply, resetting the alarm, or switching the LOCAL/REMOTE selector.
Doing so while the RUN signal is turned ON may result in injury.
Be sure to confirm permissible ranges of motors and machines before
operation because the Inverter speed can be easily changed from low to high.
Not doing so may result in damage to the product.
Provide a separate holding brake when necessary. Not doing so may result in
injury.
Do not perform a signal check during operation. Doing so may result in injury
or damage to the product.
Do not carelessly change settings. Doing so may result in injury or damage to
the product.
