17.26 5110Encoder2signalcheck  ENUM Contr A-B 0 3 ERWZ FVS
Conguration of which channels of the incremental digital encoder must be controlled for processing the Speed
fbkloss[22].
0 Check disabled
1 Check A-B
2 Check A-B-Z
4 Check A-B-SE
If set to 1, the application checks for the presence of the signals of channels A-B
If set to 2, the application checks for the presence of the signals of channels A-B-Z
If set to 4, the application controls loss of feedback for SE (single ended) encoders.
If the application detects the absence of feedback the Speedfbkloss[22] is generated.
As loss of feedback cannot be detected at speeds of around zero, the control is only performed if the speed ref-
erence is higher than the value set in parameter 4564SpdFbkLossthreshold. It is also important to consider
the fact that when working with a speed reference slightly above the limit set in parameter 4564SpdFbkLoss
threshold, the speed error could exceed the set threshold, given the load or current limit, and generate false
alarms.
In that case increase the value of parameter 4550SpdRefLossthreshold or of parameter 4554SpdRefLoss
holdoff.

Selection of the encoder direction
0 Not inverted
1 Inverted
If set to 0 the encoder feedback signals are not inverted.
If set to 1 the encoder feedback signals are inverted.

If set to 1 the frequency and period measurement method is selected. This type of measurement achieves a
high level of accuracy and performance at medium and high speeds.
If set to 2 the frequency measurement method is selected. This type of selection is preferable for applications
required to operate at very low speeds.
The other settings are relative to the type of encoder used.

Setting of the time constant of the lter applied to the reading of the feedback encoder impulses. The param-
eter affects both the precision of the speed measurement and the dynamics obtainable in the closed-loop
