Set the periods to monitor the transmission and reception steps with timers Tr, Tfr, and Tfs. The follow-

Be sure to set the periods according to the application.
The step will be retried if the step is not completed within the monitor periods. An error will occur if the
step is not completed within the monitor time again.
Note
Set a period of approximately 0.5 s each for communications with the 3G3MV.

Monitored for Tfs
period.
Monitored for Tr period.
Monitored for Tfr
period.
Ts: Send wait time set per step. Nothing is sent during this period.
Tfs: Monitors the completion of the data sent. If the data transmission is not finished within this
period, the data will be re-transmitted.
Tr: Monitors the response to be received. If the response is not returned within this period, the
response will be re-transmitted.
Tfr: Monitors the reception completion of the response. If the response transmission is not finished
within this period, the response will be re-transmitted.
Note
If the Tr period is too long, the time required to detect a communications error will be longer,
during which the Inverter cannot be controlled. Therefore, be sure to set an appropriate
period.
