Variable speed drive Altivar ATV340: Default/ fallback Motor Speed After Communication Control is lost

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
