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 test-
ing. 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 indica-
tion of abnormal condition.
If the hunting is occurred seriously, please stop the testing and oper-
ates with the load.
Be sure to check relevant parameters for the application before start-
ing 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, addi-
tional 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.

Safety Instructions
vi
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.
Be sure to set the parameters once more, in case of initialization of pa-
rameters, 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 con-
nected, 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 key-
pad.
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 out-
put. Mishandling may cause damage to the inverter.
Be sure to handle the inverter and option care in the order recom-
mended in the Electro Static Discharge (ESD) Countermeasure. Mis-
handling may lead to damage to the circuit on the PCB caused by ESD.
Countermeasure against malfunction troubles
If inverter is damaged and then gets into uncontrollable situation, the
machine may lead to the dangerous situation, therefore to avoid this
situation, be sure to install the additional equipments such as brake.
