When attachingtheparameterunacover, set the slots in the coverin the direction as illustratedandrpush to the right. Therelore, h m reroving the front cover, use caUtion not to damage the- Shields on signal wiring 0 – 5V, 0 – IOV. If the parametersare copied between differing voltage classes or differing capacities, the motorrotation may become unstable, unexpected alarms may occur, or the inverters rf-a024 may be acheved.

Switch off the start signal when resetting the inverter. The electronic motor thermal protection does not guarantee lo prevent motor burn out.

Use the connection cable available as an optional accessory to the parameter unit. Use wtput module having independent output points.


Refer to page 39 for details of initialization procdure.

Do not drop the inverter, or manuual it to impacts. Grounding Due to hgh-speed switching operation of the i n verter,leakagecurrentwill be increased corn pared to conventional inverters.

Select the necessary items by referring to the table ffr-a024 page 9 Operation Control Modes. Injury PreventionALApply only the voltage specified in the instruction manual to each terminal to prevent damage, etc.

After parameter copy from old version to new version, manually set 0 to Pr. I necessary to install a magnetic contactor MC at the primary side of the inverter as well manuwl to design a control sequence that disables the s rt signal. These wires must be routed as far as possible from the main power and AC relay logic circuits.

Take care to ensure that electromagnetic radiation from the inverter does not damage or affect the operation of nearby electrical equipment. Always ground fhe the inverter andthe motor. Change the value set for Pr. Incorrect handling might cause an unexpected fault.

InstallationInstall the inverter considering location, physical orientation ambient temperature. You may access the charged inverter circuits and get an electric shock. I1 It is necessary to securely fix the cable to t b parameter unit, use the L-pattern cable. Additional instructionsp o w.

For details, refer to page to Therefore, it is necessary to initialize the parameter set values before starting the operation.


When driving a V class W r with the inverter, use an insulation-enhamed motor, or measures should be taken to suppress the surge vottage. Avoid instaling the inverter i n tho followi n g places. Do not use disconnect switch magnetic contactor at the inverter output to start or stop the motor inverter. Surge vonages atributable to the wiring constant may occur at motor terminals, deterioraling the insulation of the motor. If the error message Err.
