General flowchart
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, E.SER).
Turn the RES signal of the inverter ON or shut off the power supply to coast the motor to a stop.
• 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.
 Setting items and set data
• After completion of parameter settings, set the instruction codes and data, then start communication from the computer to
allow various types of operation control and monitoring.
