Operation
• Only turn ON the input power supply after confirming the Digital Operator or blank
cover(optional) are in place. Do not remove the Digital Operator or the covers while
current is flowing.
Failure to observe this warning may result in an electric shock.
• Never operate the Digital Operator or DIP the switches with wet hands.
Failure to observe this warning may result in an electric shock.
• Never touch the terminals while current is flowing, even if the Inverter is stopping.
Failure to observe this warning may result in an electric shock.
• When the fault retry function is selected, stand clear of the Inverter or the load. The
Inverter may restart suddenly after stopping.
(Construct the system to ensure safety, even if the Inverter should restart.) Failure to
observe this warning may result in injury.
• When continuous operation after power recovery is selected, stand clear of the Inverter
or the load. The Inverter may restart suddenly after stopping.
(Construct the system to ensure safety, even if the Inverter should restart.) Failure to
observe this warning may result in injury.
• The Digital Operator stop button can be disabled by a setting in the Inverter. Install a
separate emergency stop switch.
Failure to observe this warning may result in injury and machine damage.
• If an alarm is reset with the operation signal ON, the Inverter will restart automatically.
Reset an alarm only after verifying that the operation signal is OFF.
Failure to observe this warning may result in injury.
• When the 3-wire sequence is set, do not make the wiring unless the multi-function input
terminal parameter is set.
Failure to observe this warning may result in injury.
• If the parameter access (n001) is set to 5, a Run command can be received via control
terminal, even while changing a constant. If sending a Run command while changing a
constant, such as during a test run, be sure to observe all safety precautions.
Failure to observe this warning may result in injury.
In case of Bi-directional function is enabled (n145=1), the motor rotation direction might
be wrong, because analogue frequency reference and digital input command might be
oppositional.
Failure to observe this warning may result in injury and machine damage.
