Communication operation and setting Parameter
6 - 458
NOTES
Always set the communication check time interval before starting operation to prevent haz-
ardous 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 sig-
nal 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, E.SER). 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.
