CAUTION

Always set the communication check time interval before starting operation to prevent hazardous
conditions.
 Data communication is not started automatically but is made only once when the computer provides
a communication request. If communication is disabled during operation due to signal cable
breakage etc., the inverter cannot be stopped. When the communication check time interval has
elapsed, the inverter output will be shut off (E.PUE).
The inverter can be coasted to a stop by switching ON the RES signals or by switching the power
OFF.
 If communication is broken due to signal cable breakage, computer fault etc., the converter unit
does not detect such a fault. This should be fully noted.
