Units: counts
Description
These Voltage registers hold the voltage feedback from each channel's analog transducer
on dual-input force or acceleration inputs. They are derived from the Channel A and B raw
counts registers, which are the values from the 16-bit analog-to-digital converters. The
Voltage registers are primarily provided for the user to set up and troubleshoot scaling.
The Channel A and B Voltage registers are used to calculate the Channel A and B Force or
Acceleration.
The Voltage registers are for axes with voltage feedback. The Current registers are for
axes with current feedback. Axes with other feedback types do not have a Current or
Voltage register; they have a Counts register.
The RMC derives the Voltage from the Raw Counts, which is the value from the Analog-
to-Digital Converter. The calculations are listed below. These are approximate, as the
analog calibration values are also included in the calculation. The levels at which the
value saturates and certain errors occur are also included.
