WARNING
!
!!
! The [STOP] key is valid only when the appropriate function setting has been made.
Prepare an emergency stop switch separately.
!
!!
! Make sure that the start signal is off before resetting the inverter alarm. A failure to
do so may restart the motor suddenly.
!
!!
! The load used should be a three-phase induction motor only. Connection of any
other electrical equipment to the inverter output may damage the equipment.
!
!!
! Do not modify the equipment.
CAUTION
!
!!
! The electronic overcurrent protection does not guarantee protection of the motor
from overheating.
!
!!
! Do not use a magnetic contactor on the inverter input for frequent starting/stopping
of the inverter.
!
!!
! Use a noise filter to reduce the effect of electromagnetic interference. Otherwise
nearby electronic equipment may be affected.
!
!!
! Take measures to suppress harmonics. Otherwise power harmonics from the
inverter may heat/damage the power capacitor and generator.
!
!!
! When parameter 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 set-
ting, 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 the inverter which had been stored for a long period, always per-
form inspection and test operation.
CAUTION
!
!!
! Provide a safety backup such as an emergency brake which will prevent the
machine and equipment from hazardous conditions if the inverter fails.
CAUTION
!
!!
! Do not carry out a megger (insulation resistance) test on the control circuit of the
inverter.
CAUTION
!
!!
! Treat as industrial waste.
Many of the diagrams and drawings in this instruction manual show the inverter
without a cover, or partially open. Never operate the inverter in this status. Always
replace the cover and follow this instruction manual when operating the inverter.
