Appendix C: Parameter Field Reference
C-87
This and the other position filter parameters can also be changed through the Reference (W)
command.
For details on reference axis filtering, see Reference Axis Filtering.
C.6.11 Reference Dead Band (Reference)
Default: 0
Range: 0 to 65,535 position units
Note: This parameter is available in RMC100 CPU firmware dated 20020222 or later.
This parameter is used to eliminate jitter in an analog reference input. It can be used in
conjunction with the filter parameters (Filter Time Constant, Velocity Limit, and Acceleration Limit)
to control the consistency of the analog reference.
The Reference Deadband works as follows. As each reading is made from the analog transducer,
it is compared with the last value that was not ignored due to the deadband. If the value is within
the Reference Deadband parameter, then it is ignored and the last value is re-used. If it is outside
the deadband, then the new value is used.
Typically, this parameter is used to obtain final smoothing after using the filter parameters to
reduce step jumps and more substantial noise.
For reference axes, the Actual Position status field reflects the actual reading from the
transducer, and the Target Position reflects the filtered position, after applying the Filter Time
Constant, Deadband, Velocity Limit, and Acceleration Limit parameters.
This and the other position filter parameters can also be changed through the Reference (W)
command.
For details on reference axis filtering, see Reference Axis Filtering.
