(2) Emulated encoder output
When emulated encoder output is selected, the signals received from the encoder will be scaled
before the signals are output to the controller. If the scaling is set to 1:1, the signals will be directly
output to the controller according to the adopted encoder and resolution setting. In some cases, such
as when the controller cannot receive encoder signals sent at high frequency, the scaling can be set
to 5:1 to let five encoder counts equal one emulated encoder output. When the multiplier factor of
analog encoder is set to a high value, scaling can also be used to lower the output resolution. If the
scaling is set to 1 encoder count = -1 emulated encoder output, the direction will be reversed. For
instance, in figure 5.2.2.3.2, the grating period of analog encoder is 20 um and the interpolated
resolution after setting the multiplier factor to 200 is 0.1 um/count. If the scaling is set to 10 encoder
counts = 1 emulated encoder output, the output resolution becomes 1 um/count.
Note:
Emulated encoder output is not available when saving parameters to Flash.
