Example:
Set parameters for any encoder
Angle encoder with line count
s = 18 000
Desired display step
a = 0.001°
Subdivision P36 =
=
=
=
= 360° / s / a = 20
Counting mode P37 = 1 (display counts 1, 2, 3, ....)
Decimal places of a: P38 = 3
Convert decimal degrees to degrees, minutes, seconds
1 degree (1°) = 60 minutes (60'); 1 minute (1') = 60 seconds (60'')
