3.3.1. MXU Option
The MXU encoder input option, is designed for a differential analog encoder in the range
of 0.6 to 2 volts (Peak to Peak). The maximum input frequency is limited to 200 kHz. The
–
MXU option multiplies the resolution programmatically up to 512 times (total). The
multiplication factor is defined by the CfgFbkEncMultFactorMXU axis parameter.
The encoder input should be adjusted for optimum performance by the
CfgFbkEncCosGain, CfgFbkEncCosOffset, CfgFbkEncPhase, CfgFbkEncSineGain,
CfgFbkEncSineOffset, CfgFbkEncMultFactorMXU axis parameters. This can be done
automatically using the
“
Encoder Feedback Configuration
”
utility. See the Soloist HMI
help for more information.
The
–
MXU option is not compatible with PSO firing capabilities because it does not
generate a serial pulse stream as required by the PSO (Position Synchronized Output)
option.
A standard differential line driver encoder must be used if this option is not present, see
Section 3.3. for more information. See the figure below for MXU typical input circuitry.
The pin out is indicated in Table 3-11.
