encoder's resolution and then multiplying it by (2*PI) rad.
For example, if a servo encoder has a resolution of 65536 counts, and the
encoder's output is 1000 counts, then the normalized position is 1000 / 65536 *
(2*PI) = 0.095873799 rad.

Work Zone
Count
counts The "Work Zone Count" telemetry is the same as "Servo Encoder Counts", but
it continuously spans in both positive and negative directions.
The "Work Zone Count" is not limited to just 360 degrees of the rotary
encoder's resolution. Instead, it logically spans in both positive or negative
directions as many encoder counts as needed. Both Servo Control and Direct
Drive Control use the logical work zone's counts at their references instead of
the physical servo encoder's readings. This makes it easier to develop "multi-
turn" servo applications.

Sample
Number
- This is a continuously incremented counter of samples taken by an ADC
module of the controller. The counter is incremented with the sampling
frequency of the controller.

Torque N*m This is an estimate of TORQUE that the motor is currently generating.
Note that this estimation is only available whenever the motor runs under
Field Oriented Control (FOC).
