for commutation setting
Example 1
, reference point
(fig. "Measuring the relative position
between primary and secondary part"):
d = 100.0 mm, k
mx
= 38.0 mm
P-0-0523 = d - k
mx
= 100.0 mm – 38.0 mm = 62.0 mm
Example 2
, reference point
(fig. "Measuring the relative position
between primary and secondary part"):
d = 0.0 mm, k
mx
= 38.0 mm
P-0-0523 = d - k
mx
= 0.0 mm – 38.0 mm = – 38.0 mm
