Safety Instructions
v
 Adjustment before starting trial operation
 Do not supply the excessive range of voltage displayed in the user manual to
the each terminal. It may cause damage to the inverter.
 Current hunting can be occurred in the low speed territory during testing. It
occurs where the capacity is above 110kW with no-load and the axis is not
connected.
The current hunting has a gap according to the motor characteristic. It will be
disappeared when the load is connected and it is not the indication of
abnormal condition.
If the hunting is occurred seriously, please stop the testing and operates with
the load.
 Be sure to check relevant parameters for the application before starting trial
operation.
 How to Use
 Be sure not to approach the machine when retry function is selected. The
machine may start working suddenly.
 Stop key on the keypad should be set to be in use. For safety, additional
emergency stop circuit should be required.
 Inverter restarts if alarm condition is cleared while FX/RX signal is on.
Therefore, be sure to operate the alarm reset switch after checking if FX / RX
signal is off.
 Never modify the inverter for inappropriate use.
 When a magnetic contactor is installed on the power source, do not
frequently start or stop using this magnetic contactor. It may cause the failure
of inverter.
 Noise filter should be used for the minimization of troubles by electro-
magnetic noise. Electronic equipments close to the inverter should be
protected against the damage caused by troubles.
 Be sure to install the AC reactor at the input of inverter in case of input
voltage unbalance. Otherwise, generator or phase-leading capacitors may
be destroyed by the harmonic current from inverter.
 If 400V class motor is used with the inverter, insulation-enforced motor
should be used or countermeasures against the suppression of micro-surge
voltage generated by the inverter should be carried out.
Otherwise, micro-surge voltage is generated across input terminal for the
motor and this voltage lowers allowable insulation break-down voltage and
then, may cause the destruction of the motor.

Safety Instructions
vi
 Be sure to set the parameters once more, in case of initialization of
parameters, all values of parameters is set to values of factory setting.
 High speed operation can be set easily, therefore be sure to check the
performance of motor or machine before changing parameter value.
 DC braking function cannot produce a zero-servo torque. If required,
additional equipment should be installed.
 When inverter trip or emergency stop (BX) occurs without keypad connected,
LED on the control board will blink by the interval of 0.5 sec. But LED will
blink by 1 sec when keypad is connected. This function displays which trip
will be occurred according to the connection of keypad.
 Do not change wiring, nor disconnect connector or option card during the
operation of inverter.
 Do not disconnect the motor wiring while the voltage of inverter is output.
Mishandling may cause damage to the inverter.
 Be sure to handle the inverter and option care in the order recommended in
the Electro Static Discharge (ESD) Countermeasure. Mishandling may lead
to damage to the circuit on the PCB caused by ESD.

 If the storage period exceeds 3 months, be sure to keep it at the ambient
temperature of -10 ~ +30˚C to prevent『Deterioration by Temperature』of
electrolytic condenser.
 Be sure to keep it in a proper package to prevent moisture, etc. Put the
desiccant (Silica Gel), etc., in the package so that the relative humidity in the
package can be maintained at 70% or less.
 When it is exposed to moisture or dust (mounted on the『System』 or
『Control Panel』, etc. installed at the construction site), remove it and then
keep it under the environmental condition specified in the page v.
Caution
 If the inverter has been left long with electric current not charged, the
nature of electrolytic condenser can be deteriorated. So be sure to
