Digital Encoder

This view allows for configuring the digital encoder parameters listed below

Encoder typeDefine whether to use a 2 or 3 channels encoder (with or without index), differential or single ended encoder.

This parameter defines the positive sense of movement based on encoder. Use the Auto identify wizard to detect it. The main steps of the wizard are:

  1. Set the current used for the test. Ranges is from 0 (min) to motor rated current (max).
  2. Set maximum test duration.
  3. Start the test to identify the encoder polarity. 
  4. A message is displayed showing the result of the test. If the test ends successful, the suggested values are displayed in a grid. If the test fails, a message is displayed giving information about the failure and how to fix it by modifying the parameters in Step 1.
Sensor resolution

For rotary motors this parameter is expressed in channel counts / revolution.
For linear motors it is expressed in nm. It is possible to enter decimal numbers in this field.

Total resolution

This parameter is automatically calculated based on the sensor resolution, and the magnetic pole pitch (in case of linear motor) or stroke (in case of voice coils).

It expresses the total resolution of the system.

Ingenia Servo Drives use x4 decoding with incremental encoders. So each transition in any of the two main encoder signals (A, B) will be considered to be an increment. As an example, if a 500CPR (cycles per revolution) encoder is used, the encoder resolution will be 2000 increments per mechanical revolution.

Quick Test

The quick test monitors in real time the encoder position read, according to actual encoder configuration and user units selected.
