Description
Feedback 3 is natively scaled to 4,294,967,296 counts per revolution for rotary motors, and 4,294,967,296
per motor pole pitch (MOTOR.PITCH (S. 917)) for linear motors. When FB3.ENCRES is non-zero, scal-
ing is applied on top of the native scaling.
Rotary Example:
A second feedback device is placed at the load which has a 1:4 gear ratio (motor does four revolutions per
secondary revolution). In this case, FB3.ENCRES should be 4,294,967,296 / 4 = 1,073,741,824
Linear Example:
Linear encoder resolution can be calculated as the number of encoder counts per one revolution of the
motor. For example, if a linear setup has a 10mm scale (100,000 counts/mm), and the ballscrew has a
10mm lead with no gearbox, it will result in 1,000,000 counts for every revolution of the motor shaft. For
this example, FB3.ENCRES should be set to 1,000,000.
