FB#.P
Description
This parameter is the 64 bit position of the feedback device. The position is given in counts. The parameter takes actual feedback position (with resolution specified in FB#.RES ) and converts it into a format of 32:32.
-
For rotary feedback, the upper 32 bits represent the number of motor turns and the lower 32 bits represent the position within one turn.
-
For linear feedback, the upper 32 bits represent the number of motor pole-pairs and the lower 32 bits represent the position within one pole-pair distance of the motor.
Example
Rotary feedback position = 542,456,123,450 or 0111 1110 0100 1100 1110 0111 1001 0000 0011 1010 binary
Number of turns = 0111 1110 binary or 126 decimal
Position within a turn = 0100 1100 1110 0111 1001 0000 0011 1010 binary or 1,290,244,154 decimal
