Delta RMC151 - Manual (Page 921)

9 Register Reference
The Noise Error Rate applies to all axes types. However, the Noise Error Rate units for
each axis type may differ. The following table shows the Noise Error Rate units for each
axis type:
Axis Type Noise Error Rate Units
Position pu/s
Velocity pu/s 2
Acceleration pu/s 3
Pressure/Force Pr/s or Fr/s
Special Notes
The Noise Error Rate does factor out the current Actual Velocity, and therefore, it won’t
trigger for simply going over speed. A high acceleration can trigger the Noise Error.
However, the Noise Error Rate should always be set much higher than the expected
velocity of the axis.

Description
The Display Units axis parameter defines the feedback units that are displayed for that
axis in RMCTools. The Display Units are solely for display purposes and do not provide
any automatic feedback scaling or conversion between units.
To set the Display Units for an axis:
1. In the Axis Tools, in the Axis Parameters, go to the Setup tab.
2. In the Primary Control Setup or Secondary Control Setup sections, find the
Display Units parameter.
3. Choose the desired units from the list, or choose Custom. If you choose Custom, you
can define your own units by entering up to four characters in the Custom Units axis
parameter.
Example 1: On a position feedback axis, the user selects mm. The position units will
be displayed as (mm).
