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.

Note It is not possible to connect a Braking Resistor or Braking Unit to a J7-series
Inverter. Select an Inverter from another series if the application requires
braking control.
International Standards (EC Directives and UL/cUL Standards)
The J7 Inverter meets the EC Directives and UL/cUL standard requirements
for worldwide use.
Versatile
Easy-to-use
Functions
• Incorporates the functions and operability ensured by the conventional
J7AZ Series.
• Easy to initialize and operate with the FREQ adjuster on the Digital
Operator.
• Ease of maintenance. The cooling fan is easily replaceable. The life of the
cooling fan can be prolonged by turning on the cooling fan only when the
Inverter is in operation.
Suppression of
Harmonics
Connects to DC reactors, thus suppressing harmonics more effectively than
conventional AC reactors.
Further improvement in the suppression of harmonics is possible with the
combined use of the DC and AC reactors.
