W Description
RES Number of bits for fine resolution Gn_XIST1
(cyclic actual encoder value)
RES Number of bits for fine resolution Gn_XIST2
(absolute value of the encoder)
RES Number of differentiable encoder revolutions for a
multi-turn absolute value encoder
(For a single-turn absolute value encoder = 1;
for an incremental encoder = 0)
RES Load distance per revolution of an externally mount-
ed encoder
