Description

The subindices have the following function:

  • 00h (Configuration): The following bits have a meaning:
    • Bit 0: Value = "0": The encoder does not have an index. Value = "1": Encoder index found and is to be used.
    • Bit 15: Value = "1": The encoder is a single-turn absolute encoder.
  • 01h (Alignment): This value specifies the offset between the index of the encoder and the electric field.

    The exact determination is only possible via auto setup. The presence of this value is necessary for closed loop mode with encoder.
