The frequency reference can be monitored or set while this indicator is lit.
The output frequency of the Inverter can be monitored while this indicator is lit.
The output current of the Inverter can be monitored while this indicator is lit.
The values set in U01 through U10 are monitored while this indicator is lit.
The direction of rotation can be selected while this indicator is lit when operating the Inverter with the RUN Key.
The operation of the Inverter through the Digital Operator or according to the set parameters is selectable while this indicator is lit.
Note This status of this indicator can be only monitored while the Inverter is in operation. Any RUN command input is ignored while this indicator is lit.
The parameters in n01 through n79 can be set or monitored while this indicator is lit.
Note While the Inverter is in operation, the parameters can be only monitored and only some parameters can be changed. Any RUN command input is ignored while this indicator is lit.
Switches the setting and monitor item indicators in sequence.
Parameter being set will be canceled if this key is pressed before entering the setting.
Increases multi-function monitor numbers, parameter numbers, and parameter set values.
Decreases multi-function monitor numbers, parameter numbers, and parameter set values.
Enters multi-function monitor numbers, parameter numbers, and internal data values after they are set or changed.
RUN Key Starts the Inverter running when the J7AZ is in operation with the Digital
Operator.
STOP/RESET Key Stops the Inverter unless parameter n06 is set to disable the STOP Key.
Functions as a Reset Key when an Inverter error occurs. (See note.)
Note For safety reasons, the reset will not work while a RUN command (forward or reverse) is in effect. Wait until the RUN command is OFF before resetting the
Inverter.
