Description

The subindices have the following function:

  • 00h: Value = "n", where "n" is the number of existing feedbacks.
  • nh: Subindex "n" contains the number of motor revolutions for the corresponding feedback.

    Subindex 01h always corresponds to the first (and always existing) sensorless feedback. Subindex 02h corresponds to internal encoder.

The gear ratio of feedback "n" is calculated as follows:

Gear Ratio = Motor Shaft Revolutions (60E8h:nh) / Driving Shaft Revolutions (60EDh:nh)
