NOTES
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 pro-
vides 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 will come to an alarm stop (E.PUE). The inverter can be coasted to a stop by
switching on its RES signal or by switching power off.
If communication is broken due to signal cable breakage, computer fault etc., the inverter does
not detect such a fault. This should be fully noted.
