Determines encoder function/purpose. The encoder can be configured for commutation, motion control feedback and monitoring. In monitoring mode, the position and velocity information will be displayed in objects #0x230A & #0x230B. There is an option to configure two motion sensors, one sensor as a motion position sensor, while the other sensor should have commutation and velocity function. 

Note that commutation can also be performed with ABI and Hall sensors combined. This exploits the benefits of both principles: the high resolution angle from the ABI encoder and the absolute electrical position provided by the Hall sensor.

Resolution 0x2206:3 UDINT 32 1 1 Inc/Revolution readwrite

Total number of quadrature edges per revolution.

Resolution = Cycles per Revolution * 4

 

Note:

Cycles = Pulses = Lines

Positions = Counts = Increments = 4 * Cycles

Zero velocity threshold 0x2206:4 UDINT 32 0 1000000 5000 μs readwrite

Time threshold to set the velocity to 0 if no new position was received from the encoder.

Normal Polarity 0
Inverted Polarity 1
readwrite

If you have an axis with two encoders (one for commutation and one for position and velocity), the direction of each encoder must match for control stability. This polarity parameter can be used for flipping the direction of the position or velocity encoder relative to the sensor used for commutation.
