Ambient operating temperature: Panel-mounting models (conforming to IP20): –10 to 50°C (0.1- to 3.7-kW Inverters) Closed wall-mounting models (conforming to NEMA1 and IP20): –10 to 40°C (5.5- to 7.5-kW Inverters) Humidity: 95% max. (with no condensation) Note 1. By removing the top and bottom covers from a 5.5- to 7.5-kW Inverter, it can be used as a panel-mounting model (conforming to IP00) within an ambient temperature range of –10 to 50°C. Note 2. All C-type Inverters (closed wall-mounting models: NEMA1-type for North America) are closed wall-mounting models, and can be used within an ambient temperature range of –10 to 40°C. If the top and bottom covers are removed, the C-type Inverters can be used as panelmounting models (conforming to IP00) within an ambient temperature range of –10 to 50°C. • Install the Inverter in a clean location free from oil mist and dust. Alternatively, install it in a totally enclosed panel that is completely protected from floating dust. • When installing or operating the Inverter, always take special care so that metal powder, oil, water, or other foreign matter does not get into the Inverter. • Do not install the Inverter on inflammable material such as wood. • If a 5.5- to 7.5-kW Inverter or a C-type Inverter is to be installed inside of a control panel, it must have the top and bottom covers removed and be used as a panel-mounting model (conforming to IP00). H Direction • Install the Inverter on a vertical surface so that the characters on the nameplate are oriented upward. H Dimensions • When installing the Inverter, always provide the following clearances to allow normal heat dissipation from the Inverter. W = 30 mm min. (0.1 to 4.0 kW) 50 mm min. (5.5 to 7.5 kW) Inverter Inverter 100 mm min. Inverter Side 100 mm min. 1-6 Air Air Design Chapter 1 H Ambient Temperature Control • To enhance operation reliability, the Inverter should be installed in an environment free from extreme temperature changes. • If the Inverter is installed in an enclosed environment such as a box, use a cooling fan or air conditioner to maintain the internal air temperature below 50°C. The life of the built-in electrolytic capacitors of the Inverter is prolonged by maintaining the internal air temperature as low as possible. • The surface temperature of the Inverter may rise approximately 30°C higher than the ambient temperature. Be sure to keep away equipment and wires from the Inverter as far as possible if the equipment and wires are easily influenced by heat. H Protecting Inverter from Foreign Matter during Installation • Place a cover over the Inverter during installation to shield it from metal power produced by drilling. Upon completion of installation, always remove the cover from the Inverter. Otherwise, ventilation will be affected, causing the Inverter to overheat. 1-1-2 Removing and Mounting the Covers To mount the Inverter, it is necessary to remove the front cover, terminal cover (unless the Inverter is a 200-V model), and the Digital Operator.

FREQ adjuster Sets the frequency reference within a range between 0 Hz and the maximum frequency. FREF indicator 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 U-01 through U-18 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 parameters set is selectable while this indicator is lit. FOUT indicator IOUT indicator MNTR indicator F/R indicator LO/RE indicator PRGM indicator 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 n001 through n179 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. The RUN command input is ignored while this indicator is lit. 2-2 Preparing for Operation and Monitoring Appearance Name Mode Key Increment Key Chapter 2 Function Switches the simplified-LED (setting and monitor) item indicators in sequence. Parameter setting being made is canceled if this key is pressed before entering the setting. Increases multi-function monitor numbers, parameter numbers, and parameter set values. Decrement Key Decreases multi-function monitor numbers, parameter numbers, and parameter set values. Enter Key Enters multi-function monitor numbers, parameter numbers, and internal data values after they are set or changed. Starts the Inverter running when the 3G3MV is in operation with the Digital Operator. RUN Key STOP/RESET Key Stops the Inverter unless n007 is not 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. 2-3 Chapter 2 Preparing for Operation and Monitoring 2-1-2 Accepting Operation Commands While Changing Parameters With the default settings, the Inverter will not accept operation commands when parameter settings are being changed. This functions as a safety measure to prevent the motor from rotating if the operation command is mistakenly set to ON when changing parameters. Depending on the operating conditions, however, the user may want to have operation commands accepted even while parameters are being changed. In that case, change the following settings. H Using the Indicators to Determine When Operation Commands Can Be Accepted The indicators on the Digital Operator can be used to determine if operation commands will be accepted or not while changing parameters. Green: Operation commands will be accepted if the indicator lights green. Red: Operation commands will not be accepted after the Inverter stops if an indicator lights red. Therefore, if the indicator lights red when changing parameters or when switching between local and remote operation, operation will continue, but once the Inverter stops, the Inverter will not operate even if the operation command is set to ON again. The FREF indicator will light when the power supply is turned ON. Indicator Color FREF FOUT IOUT MNTR F/R Green Green Green Green Green LO/RE PRGM Red Red Name Frequency Reference/Monitor Output Frequency Monitor Output Current Monitor Multi–function Monitor Operator RUN command forward/reverse operation selection Local/Remote Selection Parameter Number/Setting Acceptance of operation commands During Stopped operation Yes Yes Yes No ((See note.)) Note Perform the settings given in the following description to have operation commands accepted while the red indicator is lit (i.e., while changing parameters or switching between local and remote.) Set n001 (Parameter write–prohibit selection/parameter initialization) to 5. S The default value for n001 is 1. S Operation commands will not be accepted when n001 itself is being changed. S Some parameters cannot be changed during operation. Those parameters cannot be changed during operation even if the setting for n001 is changed. S When n001 is changed to 5, an operation command will be accepted even when changing parameters, such as during trial operation. Thoroughly check safety before changing any setting. 2-4 Preparing for Operation and Monitoring Chapter 2 2-1-3 Outline of Operation H Selecting Indicators Whenever the Mode Key is pressed, an indicator is lit in sequence beginning with the FREF indicator. The data display indicates the item corresponding to the indicator selected. The FOUT or IOUT indicator will be lit by turning the Inverter ON again if the Inverter is turned OFF while the FOUT or IOUT indicator is lit. The FREF indicator will be lit by turning the Inverter ON again if the Inverter is turned OFF while an indicator other than the FOUR or IOUT indicator is lit. Power On FREF (Frequency Reference) Monitors and sets the frequency reference. FOUT (Output Frequency) Monitors the output frequency. Note This indicator will be lit by turning the Inverter ON again if the Inverter is turned OFF while this indicator is lit. IOUT (Output Current) Monitors the output current. Note This indicator will be lit by turning the Inverter ON again if the Inverter is turned OFF while this indicator is lit. MNTR (Multi-function Monitor) Monitors the values set in U-01 through U-18. F/R (Forward/Reverse Rotation) Selects the direction of rotation. LO/RE (Local/Remote) Selects the operation of the Inverter through the Digital Operator or according to the parameters. PRGM (Parameter Setting) Monitors or sets the values in n001 through n179. The FREF indicator is lit again. Note The setting unit of the frequency reference and output frequency is determined by the set value in n035. The default unit is Hz. 2-5 Chapter 2 Preparing for Operation and Monitoring H Example of Multi-function Display Key sequence Indicator Display Explanation Power On Press the Mode Key repeatedly until the MNTR indicator is lit.
