Before you use the AuxiliaryEncoderMultiplicationFactor parameter:

  1. Set the FeedbackInput0 Parameter or the FeedbackInput1 Parameter to Auxiliary Feedback.
  2. Set the AuxiliaryFeedbackType Parameter to IncrementalEncoderSineWave.

IMPORTANT: If you change the value of this parameter, you must adjust other parameters.

The AuxiliaryEncoderMultiplicationFactor parameter specifies the multiplication factor of the optional auxiliary encoder multiplier module of the drive. If you set this parameter to a value greater than 1, then the effective resolution of the encoder increases by the factor that you specify.

The multiplier module is designed to work only with encoders that generate an analog output. The auxiliary encoder multiplier module applies only when you connect an encoder to the auxiliary encoder input.

The table that follows gives the maximum values of this parameter by drive type.

The iXR3 and XR3 with the -CT4 multiplier option are the only drives that can generate quadrature from the auxiliary multiplier module. Quadrature is generated only if the quadrature multiplication factor is greater than 4.

The quadrature multiplication factor is equal to the value of the AuxiliaryEncoderMultiplicationFactor parameter divided by the value of the AuxiliaryEmulatedQuadratureDivider parameter. See to the equation that follows.
