!
machine may abruptly start when stopped by an alarm. Doing so may result in injury.
WARNING Do not come close to the machine immediately after resetting momentary power
!
interruption to avoid an unexpected restart (if operation is set to be continued in the processing selection function after momentary power interruption is reset). Doing so may result in injury.
WARNING Provide a separate emergency stop switch because the STOP Key on the Operator
!
is valid only when function settings are performed. Not doing so may result in injury.
WARNING Be sure to confirm that the RUN signal is turned OFF before turning ON the power
!
supply, resetting the alarm, or switching the LOCAL/REMOTE selector. Doing so while the RUN signal is turned ON may result in injury.

!
place fans while power is being supplied. Doing so may result in injury, damage to the product, or malfunction.
Warnings for UL/cUL Marking
Do not connect or disconnect wiring, or perform signal checks while the power supply is turned ON.
The Inverter internal capacitor is still charged even after the power supply is turned OFF. To prevent
electrical shock, disconnect all power before servicing the Inverter. Then wait at least one minute after the power supply is disconnected and all indicators are OFF.
Do not perform a withstand voltage test on any part of the Inverter. This electronic equipment uses semiconductors and is vulnerable to high voltage.
Do not remove the Digital Operator or the blank cover unless the power supply is turned OFF. Never touch the printed control board (PCB) while the power supply is turned ON.
The Inverter is not suitable for use on a circuit capable of delivering more than 5,000 RMS symmetrical amperes, 250 volts maximum (100-V-class Units).
Take measures against overcurrent, overload, and overheating by using the Motor Protection Set­tings.
CAUTION
Use 75°C copper wires or equivalent. Low voltage wires shall be wired with Class I Wiring.
H Motor Protection Settings
Rated Motor Current (n32)
Set the rated motor current (n32) in order to prevent the motor from burning due to overloading.
Check the rated current on the motor nameplate and set the parameter.

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 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.
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.
Inverter
100 mm min. Air
SideInverter Inverter
100 mm min. Air
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.

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.

Used to set the electric thermal char­acteristics of the motor to be con­nected in 1-minute increments.
Note The default setting does not
require any changes in normal operation.
Note To set the parameter accord-
ing to the characteristics of the motor, check with the motor manufacturer the thermal time constant and set the parame­ter with some margin. In other words, set the value slightly shorter than the thermal time constant.
Note To detect motor overloading
quicker, reduce the set value, provided that it does not cause any application problems.
Used to operate the Cooling Fan of the Inverter while the Inverter is turned on or only while the Inverter is in operation.
0: Rotates only while RUN command
is input and for 1 minute after In­verter stops operating
1: Rotates while Inverter is turned on Note This parameter is available
only if the Inverter incorpo­rates a Cooling Fan.

4-1-1 Fault Detection (Fatal Error)
The Inverter will detect the following faults if the Inverter or motor burns or the internal circuitry of the Inverter malfunctions. When the Inverter detects a fault, the fault code will be displayed on the Digital Operator, the fault contact output will operate, and the Inverter output will be shut off causing the motor to coast to a stop. The stopping method can be selected for some faults, and the selected stopping method will be used with these faults. If a fault has occurred, refer to the following table to identify and correct the cause of the fault. Use one of the following methods to reset the fault after restarting the Inverter. If the operation command is being input, however, the reset signal will be ig­nored. Therefore, be sure to reset the fault with the operation command turned off. S Turn on the fault reset signal. A multi-function input (n36 to n39) must be set to 5 (Fault

(Check that there is no abnormal noise or vibration, and that the total ON time has not exceeded the specified value.)
H Periodic Maintenance of Components
The Inverter is constructed from many components, the normal operation of which is required for the essential functionality of the Inverter. Maintenance is required for some of the electronic components depending on the operating conditions. To enable the Inverter to operate normally for a long time, peri­odic inspection and component replacement must be performed to suit the service life of these compo­nents.
(Source: “Instructions for Periodic Inspection of General Purpose Inverter” (JEMA))
The guidelines for periodic inspection depend on the Inverter’s installation environment and operating conditions.
The maintenance periods for the Inverter are listed below. Use this to determine when periodic mainte­nance 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 is 40°C, the load rate is 80%, the operating time is 8 hours per day, and the product is installed according to the instructions in the manual.
