Running the Motor from the Parameter Unit Changing the Monitor Screen Applying the Help Function Calibrating the Frequency Meter Magnetic Flux Vector Control Switch-over Function Currents and Powers Please handle the inverter properly in accordance with as the the information on each section as well precautions and instructionsof this manual.

Power supply -. Handling Points Power supply specifications Usethepowersupplywithinthepermissiblepower supply specifications of the inverter. No-fuse breaker or earth leakage circuit breaker I : Refer To: The breaker should be selected with care since a large inrush current flows in the inverter at power on.

When breaker ELB it usenot installed, Fuse do or inverter. Use the inverter at the ambient temperature as low as possible permissible within the range. Wrongwiringmightlead to inverter damage. The controlsignallinesmustbekeptsufficientlyawayfrom P.

Topreventaccidentalelectricshock,themotorand inverter must be grounded. Unpack and check the following: 1 Check the capacity plate on the inverter front cover and the rating plate on the inverter side face, and ensure that the type and output rating agree with your order. If you have found any discrepancy, damage, etc. For these models, the parameter unit is available as an option.

FR-AK to 55K. Rating plate Capacity plate Front cover installation screws The chassis and cover are made of steel plate.

This model is not equipped with a brake resistor. See Fig. To reinstall the front cover, fit the sockets at the cover bottom into the catches of the inverter, and securely press the cover against the inverter using the catches as supports. To reinstall the front cover, insert the catches inside the cover top into the sockets of the inverter, press the cover against the inverter, and fix it with the bottom screws.

Catch -I Socket Fig. Note: 1 Fully check that the front cover has been reinstalled securely. Before reinstalling the front cover, check the serial number to ensure that the cover removed is installed to the inverter from which it has been removed. Note: 1 Do not use any solvent, such as acetone, benzene and toluene, that will cause the inverter surface to dissolve and the paint to peel. Note: 2 Do not clean the lens of the inverter LED with a detergent or alcohol which will easily affect the lens.

To reinstall, fit the fixing hole of the parameter unit into the catch of the cover, then push it into the inverter using the catch as a support. Note: Do not install the parameter unit when the front cover does not exist on the inverter. When installing the parameter unit, do not apply force to the display liquid crystal area.

Fixing hole - Fig. To reinstall, fit the fixing hole into the catch of the cover and push the cover into the inverter. Otherwise the parameter unit will not function. Read and write of the parameters Pr. Any attempt to set the above parameters results in Err display. In addition, the function of reading and copying a batch of parameters to another inverter cannot be used. Hold the inverter so as not to apply force only to the front cover of the inverter.

Install the inverter in a clean place or inside a to- tally enclosed panel which does not accept any suspended matter. Note: When the inverter is installed in a panel, determine the cooling method and panel dimensions so that the ambient temperature of the inverter is within the permissible range as specified on page Extreme care must be taken when two or more inverters are installed and a ventilation fan is mounted in the panel.

Like the inverter, protect the parameter unit from direct sunlight, high temperature and high humidity. To prevent problems, install the inverter on an incom- bustible backplate such as metal. L Cooling fan built Fig. Notes on Wiring 1 The power must not be applied to the output terminals U, V, W , otherwise the inverter will be damaged.

In addition, these terminals must not be shorted. Run the ca- bles so that they do not occupy much of the control box terminal block space. Design Information to Be Checked 1 Theinverterwillbedamagednotonly by MC1 miswiring but also by a sneak current from the power supply if there is a commercial power supplyPower!

When a machine restart is to be prevented at power restoration, provide a magnetic contactor MC in the primary circuit of the inverter and also make up a sequence which will not switch on the start signal. STF of the control circuit. Apply a voltage via a relay coil, lamp, etc. Refer to page and for the terminal block arrangement. If they are connected to U, V, W, the inverter will nd be damaged.

Phase sequence need not be matched. To keep the alarm signal on, terminals R1 and S1 areavailable. Inthiscase,connectthe power supply terminals R 1 and S1 of the control circuit to the primary side of the MC. For a different power supply system which takes the power supply of the control circuit from other than the primary side of the MC, this voltage should be equal to the main circuit voltage.

J Pull out. R1 S1 terminal. Terminal block for seperate power supply Terminal block for seperate power supply Fig.

Note': The power supply cable mustnot be connected onlyto the upper terminalto protect the inverter from damage. Only when the built-in brake resistor cannot thermally accept operation at high duty, disconnect the jumper from across termi- nals P R - P X. Inplace of thatresistor,connecttheexternaldedicatedbrakeresistor option across terminals P and PR. Do not connect any brake resistor other than the dedicated brake re- sistor.

Do not connect the external brake resistor with the terminals between PR-PX shorted, oth- erwise inverters miaht be damaaed.

Otherwise, the reac- tor will not operate. Note: 1. The wiring distance should be within 5m. The DC reactor cannot be used with the inverters of 3.

To prevent accidental electric shock, the motor and inverter must be grounded class 3 grounding Ground the inverter by connecting i t to the dedicated ground terminal.

Do not use the screw in the case, chassis, etc. Refer to page for the terminal block arrangement. Use shielded or twisted cables for connection to the control circuit terminals and run them away from the main and power circuits including the V relay sequence circuit.

Since the frequency setting signals are micro currents, use two parallel micro signal contacts or a twin contact to prevent a contact fault. This calibration potentiometer is not required when making calibration from the parameter unit.

Input signal switching can be done from the parameter unit. The output terminals other than the running RUN terminal allow alarm definition to be output in alarm codes and nine functions to be assigned individually.
