Encoder evaluation

 

Note that this configuration menu is only displayed if the function is activated in the "Basic settings" configuration menu under "Additional functions".

Note that the modulo reference may be lost when an encoder error is acknowledged.

Parameter designation

Description

Position controller

Encoder source

Selection of the encoder source:

  • Motor encoder
  • External encoder
  • Motor encoder and external encoder

An encoder that has a lower resolution than a motor encoder for the same distance is referred to as a low-resolution encoder or external encoder. An encoder that has a resolution similar to that of a motor encoder for the same distance is referred to as a high-resolution encoder.

Index: 50013.1

IEC name: Controller.EncoderEvaluation.Config.eActPos_EncSelector

Settings of external encoders

INFORMATION: Only visible if encoder source is "External encoder" or "Motor encoder and external encoder".

Type

Select whether the external encoder on the inverter is read via an option card or via the MOVIKIT® EncoderInterface:

  • Encoder 2 connected to inverter
  • EtherCAT® encoder

Index: 50013.9

IEC name: Controller.EncoderEvaluation.Config.eActPos_EncSelector

Source of EtherCAT® encoder

INFORMATION: Only visible if type is "EtherCAT® encoder".

Selection of the name of the EncoderInterface that is to be considered the encoder source of the respective member. If the EtherCAT® encoder is only required for the position controller, it is sufficient to connect "Source of EtherCAT® encoder axis group member 1".
