Safety Instructions
v
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 un-
balance. 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 generat-
ed 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.
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 ac-
cording 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. Mishan-
dling 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.
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.
Maintenance, inspection and parts replacement
Do not perform the megger (insulation resistance check) test on the control board.
Please refer to intervals for parts replacement on Chapter 8.
Disposal
Handle the inverter as an industrial waste when disposing of it.
Our inverter contains the raw material of value that can be recycled from the aspect
of energy and resource preservation. All the package materials and metal parts are
recyclable. Plastics are also recyclable, but may be burnt under the controllable en-
vironment depending on the local regulation.
