Encoder test
Use this test to check the signals of the 11 µApp or 1 Vpp interface,
the EnDat interface or the voltage at the analog module.

If you have configured the ND for two axes in the APPLICATION
field under COUNTER SETTINGS, you can perform the test for the
two possible encoder inputs.
 Select input X1 or X2 and press ENTER.
Encoders with 11 µApp or 1 Vpp interface:
 As the encoder is moved, you will see the signals of the A and B
channels as Lissajous figure (see Fig. II.49), as well as the
amplitude, symmetry and phase offset values.
