When a 400V class motor is inverter-driven, it should be insulation-enhanced or
surge voltages suppressed. Surge voltages attributale to the wiring constants
may occur at the motor terminals, deteriorating the insulation of the motor.
!
When parameter clear or all clear is performed, each parameter returns to the
factory setting. Re-set the required parameters before starting operation.
!
The inverter can be easily set for high-speed operation. Before changing its
setting, fully examine the performances of the motor and machine.
!
In addition to the inverter's holding function, install a holding device to ensure
safety.
!
Before running an inverter which had been stored for a long period, always
perform inspection and test operation.
( 5 ) Emergency stop
!
Provide a safety backup such as an emergency brake which will prevent the
machine and equipment from hazardous conditions if the inverter fails.
( 6 ) Maintenance, inspection and parts replacement
!
Do not carry out a megger (insulation resistance) test on the control circuit of
the inverter.
( 7 ) Disposing of the inverter
!
Treat as industrial waste.
( 8 ) General instructions
Many of the diagrams and drawings in this instruction manual show the inverter
without a cover, or partially open. Never operate the inverter like this. Always
replace the cover and follow this instruction manual when operating the inverter.
