2.5.1.3. Sine Wave Encoder [-MX3 Option]

The Sine Wave Encoder option provides higher positioning resolution by subdividing the fundamental
output period of the encoder into smaller increments. The amount of subdivision is specified by the
AuxiliaryEncoderMultiplicationFactor parameter. Use Encoder Tuning [A3200: Feedback Tuning] to
adjust the value of the gain, offset, and phase balance controller parameters to get the best
performance. For more information, refer to the Help file.
You cannot use the sine wave encoder on the auxiliary connector with the -MX3 multiplier option as an
input to the PSO. The -MX3 option does not generate emulated quadrature signals from the auxiliary
connector.
For the highest performance, use twisted pair double-shielded cable with the inner shield connected to
signal common and the outer shield connected to frame ground. Do not join the inner and outer shields
in the cable.
