When to Input the RUN Command after
Establishment of Communications
For safety reasons, this CompoNet Communications Unit is designed to ignore the input of the RUN com-
mand (Forward/Stop or Reverse/Stop) executed (turned ON) before communications are established.
This section describes when to input the RUN command via CompoNet after establishment of commu-
nications.
The CompoNet Communications Unit executes the process of communication connection with the
Master Unit in any of the following situations to establish communications.
You can check whether or not communications are established with the Participation/Communications
Error Flags on the Master Unit.
• When the inverter (CompoNet Communications Unit) is powered on.
• When the inverter (CompoNet Communications Unit) is reset.
• When communications are re-established from the Master Unit.
• When the inverter (CompoNet Communications Unit) is newly connected to the network
The RUN command (Forward/Stop or Reverse/Stop) must be input to the CompoNet Communications
Unit in the following timing after communications are established.
• Upon establishment of communications, the CompoNet Communications Unit sends the inverter
ready signal.
• After confirming the inverter ready signal, the RUN command is input.
• If the CompoNet Communications Unit recognizes the RUN command successfully and the inverter
moves to a RUN state, it outputs the inverter running (During forward run or During reverse run) signal.
*1 You can check the communication cycle time of CompoNet communications from the following table.
Because the Communication Cycle Time of CompoNet communications varies depending on the network con-
figuration, after network configuration changes, be sure to check the Communication Cycle Time and, when
necessary, review the input timing of the RUN command.
