Elmo SimplIQ Series - AB[N] - Absolute Encoder Setting Parameters

AB[N] – Absolute Encoder Setting Parameters
Purpose:
Configuration parameters for absolute sensor implementation of the SimplIQ drive series:
Command Description
AB[1] An absolute position resolution (number of abs. position readings) per
analog signal cycle.
AB[2]
For internal use only
AB[3] Bit-field value, see definitions below
AB[4] Absolute value direction:
0: Keep the original value as received from the sensor
1: Invert the original value. Absolute value for calculating absolute position
is AB[5] – absolute value.
AB[5] Maximum value of the absolute position sensor:
For rotation encoders - 2
(Single_Turn+Multi_Turn)
For linear encoders -

AB[6] Signal Period Length in nm (0.001um) for linear encoders or Signal Periods
per Revolution for rotation encoders
