Operation
WARNING:
P
● When you have chosen the retry function, stay away from the equipment as it will
restart suddenly after an alarm stop.
● Since pressing STOP/RESET key may not stop output depending on the function
setting status, provide a circuit and switch separately to make an emergency stop
(power off, mechanical brake operation for emergency stop, etc.).
● Make sure that the start signal is off before resetting the inverter alarm. A failure
to do so may restart the motor suddenly.
● The inverter can be started and stopped via the serial port communications link or
the field bus. However, please note that depending on the settings of the
communications parameters it may not be possible to stop the system via these
connections if there is an error in the communications system or the data line. In
configurations like this it is thus essential to install additional safety hardware that
makes it possible to stop the system in an emergency (e.g. controller inhibit via
control signal, external motor contactor etc). Clear and unambiguous warnings
about this must be posted on site for the operating and service staff.
● The load used should be a three-phase induction motor only. Connection of any
other electrical equipment to the inverter output may damage the inverter as well
as the equipment.
● Do not modify the equipment.
● Do not perform parts removal which is not instructed in this manual. Doing so may
lead to fault or damage of the inverter.
