If the inverter does not receive any valid serial telegram after the time
programmed at P314 has elapsed, the Fault Message E28 on the HMI
and the inverter will return to the action programmed at P313 - Type of
Disabling by E28/E29/E30.
To enable the inverter to execute this action, the inverter commands
must be programmed to the “Serial” option at the parameters P220 to
P228.
