(2) Wiring
Do not fit capacitive equipment such as power factor correction capacitor, radio
noise filter (option FR-BIF) or surge suppressor to the output of the inverter.
The connection orientation of the output cables U, V, W to the motor will affect the
direction of rotation of the motor.
(3) Trial run
Check all parameters, and ensure that the machine will not be damaged by a
sudden start-up.
(4) Operation
When you have chosen the retry function, stay away from the equipment as it will
restart suddenly after an alarm stop.
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.
The electronic thermal relay function 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 supply harmonics from
the inverter may heat/damage the power capacitor and generator.
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.
