Installation Direction and Dimensions• Install the Inverter under the following conditions.

Ambient temperature for operation (panel-mounting): –10°C to 50°C

Humidity: 95% or less (no condensation)

• Install the Inverter in a clean location free from oil mist and dust. Alternatively, install it in a totally en-closed panel that is completely protected from floating dust.

• When installing or operating the Inverter, always take special care so that metal powder, oil, water, orother foreign matter does not get into the Inverter.

• Do not install the Inverter on inflammable material such as wood.

Direction• Install the Inverter on a vertical surface so that the characters on the nameplate are oriented upward.

Design Chapter 1

Dimensions• When installing the Inverter, always provide the following clearances to allow normal heat dissipation

from the Inverter.

W = 30 mm min.

Inverter

100 mm min. Air

SideInverter Inverter

100 mm min. Air

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 conditionerto 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 airtemperature as low as possible.

• The surface temperature of the Inverter may rise approximately 30°C higher than the ambient temper-ature. Be sure to keep away equipment and wires from the Inverter as far as possible if the equipmentand wires are easily influenced by heat.

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 willbe affected, causing the Inverter to overheat.

2-1-2 Accepting Operation Commands While ChangingParameters

With the default settings, the Inverter will not accept operation commands when param-eter settings are being changed. This functions as a safety measure to prevent the motorfrom rotating if the operation command is mistakenly set to ON when changing parame-ters.Depending on the operating conditions, however, the user may want to have operationcommands accepted even while parameters are being changed. In that case, changethe following settings.

Using the Indicators to Determine When Operation Commands Can BeAccepted

The indicators on the Digital Operator can be used to determine if operation commands will be acceptedor 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 andremote operation, operation will continue, but once the Inverter stops, the Inverter will not operate evenif the operation command is set to ON again.

The FREF indicator will light when the power supply is turned ON.

( )

Note Perform the settings given in the following description to have operation commands acceptedwhile the red indicator is lit (i.e., while changing parameters or switching between local and re-mote.)

Set n01 (Parameter write–prohibit selection/parameter initialization) to 5.

The default value for n01 is 1.

Operation commands will not be accepted when n01 itself is being changed.

Some parameters cannot be changed during operation. Those parameters cannot be changedduring operation even if the setting for n01 is changed.

When n01 is changed to 5, an operation command will be accepted even when changing pa-rameters, such as during trial operation. Thoroughly check safety before changing any setting.

4-1-1 Fault Detection (Fatal Error)

The Inverter will detect the following faults if the Inverter or motor burns or the internalcircuitry of the Inverter malfunctions. When the Inverter detects a fault, the fault code willbe displayed on the Digital Operator, the fault contact output will operate, and theInverter output will be shut off causing the motor to coast to a stop. The stopping methodcan be selected for some faults, and the selected stopping method will be used withthese faults. If a fault has occurred, refer to the following table to identify and correct thecause of the fault. Use one of the following methods to reset the fault after restarting theInverter. If the operation command is being input, however, the reset signal will be ig-nored. Therefore, be sure to reset the fault with the operation command turned off. Turn on the fault reset signal. A multi-function input (n36 to n39) must be set to 5 (Fault

Reset). Press the STOP/RESET Key on the Digital Operator. Turn the main circuit power supply off and then on again.

• Cooling fan in control panel is operating normally(Check that there is no abnormal noise or vibration, and that the total ON time has not exceeded thespecified value.)

Periodic Maintenance of ComponentsThe Inverter is constructed from many components, the normal operation of which is required for theessential functionality of the Inverter. Maintenance is required for some of the electronic componentsdepending on the operating conditions. To enable the Inverter to operate normally for a long time, peri-odic inspection and component replacement must be performed to suit the service life of these compo-nents.

(Source: “Instructions for Periodic Inspection of General Purpose Inverter” (JEMA))

The guidelines for periodic inspection depend on the Inverter’s installation environment and operatingconditions.

The maintenance periods for the Inverter are listed below. Use this to determine when periodic mainte-nance is required.

The guidelines for periodic maintenance are as follows:

• Cooling fan: 2 to 3 years

• Electrolytic capacitor: 10 years

• Fuse: 10 years

These guidelines are applicable for an operating environment in which the ambient temperature is40°C, the load rate is 80%, the operating time is 8 hours per day, and the product is installed according tothe instructions in the manual.


4-11

To extend the maintenance period, it is recommended to lower the ambient temperature and shortenthe ON time as much as possible.
