Unit Description / Notes
If this parameter is set to ON, the bit #6 of the control word shall be kept
in 1 to the inverter operation. It will allow the inverter to be disabled in
case of STOP in the master of the Fieldbus network, where the control
word is reset (all bits are set to zero).

Defines the inverter behavior when the serial communication is inactive
(causing error E28), when physical connection with the master of the
Fieldbus is interrupted (causing error E29) or when the Fieldbus board
is inactive (causing error E30). Refer to item 8.12.7.
For P313 = 4, when the inverter detects Fieldbus communication fault
and changes from Remote to Local mode, then the Start/Stop and the
speed reference commands the inverter was receiving in Remote mode
will be kept in Local mode, if these commands were 3-wire Start/Stop
and Electronic Potentiometer or Start/Stop and reference via HMI.
For P313 = 5, when the inverter detects Fieldbus communication fault,
a fatal error will be generated in the equipment, disabling the motor and
making it necessary an error reset, so that the operation be possible
again.
