C-1.1 Reset Speed fbk loss alarm
The reasons for activating the Speed fbk loss alarm and the information acquired by the encoder are shown in
parameter 2172 SpdFbkLoss code.
If no card has been installed the Speed fbk loss [22] alarm is generated and no cause is displayed in
parameter 2172 SpdFbkLoss code. Several causes may be present at the same time.
If no card is recognised, the system runs a routine that always returns Speed fbk loss [22] active without
specifying a cause.
