It is possible to configure fallback function. It is the speed that will be applied to the motor when communication is lost.
How to configure it?

For modbus RTU communication :

In fieldbus monitoring set SLL=fallback speed and LFF=xx Hz (fallback speed).
Modbus timeout is set in parameter TTO

For embedded ethernet (ATV340...E) :
ETHL = fallback speed, LFF = xx Hz (fallback speed)

For other type of communication search associated setting in Somove software, in section : Error / warning handling - Communication module
or via VW3A1111 keypad connected to ATV340, search associated setting in the same section Error / warning handling - Communication module
