HARDWARE: This parameter applies only to the iXR3 or XR3 that uses the -CT4 encoder multiplier option.
Before you use the AuxiliaryEncoderMultiplierSetup parameter:
- Set the FeedbackInput0 Parameter or the FeedbackInput1 Parameter to Auxiliary Feedback.
- Set the AuxiliaryFeedbackType Parameter to IncrementalEncoderSineWave.
The AuxiliaryEncoderMultiplierSetup parameter configures the settings related to the optional encoder multiplier module of the drive. The sections that follow give the possible settings for this parameter.
Velocity Filtering
HARDWARE: This parameter applies only to the drives and configurations that follow:
This setting specifies the level of filtering that the drive does on the feedback from the
When you select None, the drive does not do filtering. This configuration causes higher overall noise and is not recommended.
When you select Level 1, the drive does a basic level of filtering. This configuration causes higher overall noise than the default configuration. Use Level 1 only if the default configuration is not satisfactory.
Level 2 is the default and is recommended for most systems. The drive does a standard level of filtering.
When you select Level 3, the drive does an increased level of filtering. This configuration can cause lower overall noise than the default configuration, but it can also cause a loss of phase margin in the servo loop.
High Speed Mode
This setting enables the High Speed Mode on the applicable drive type.
Disabled is the default. If it is not necessary for the drive to track encoder frequencies higher than 450 kHz, select this value. The increased bandwidth A measurement, expressed in frequency (hertz), of the range which an amplifier or motor can respond to an input command from DC to -3dB on a frequency sweep. decreases the noise performance of the encoder input.
When you select Enabled, the controller increases the bandwidth A measurement, expressed in frequency (hertz), of the range which an amplifier or motor can respond to an input command from DC to -3dB on a frequency sweep. of the MX encoder input circuit to let the drive track encoder frequencies up to a maximum of 2 MHz. You can calculate the maximum encoder frequency of your axis by using the equation that follows:
