# Encoder resolution via feed constant numerator (P-AXIS-00362)

P-AXIS-00362 | Encoder resolution via feed constant (numerator)
Description | Parameter P-AXIS-00362 and parameter P-AXIS-00363 enable anm alternative method to parameterise encoder resolution. If either parameter P-AXIS-00362 or P-AXIS-00363 are assigned values unequal to 1 (default initialisation), encoder resolution is calculated based on the equation below:

where:

R: Resulting resolution (Increments / 0.1µm)

rMotor: Encoder increments per motor revolution (P-AXIS-00092)

iGetriebe; Gear transmission ratio (Revolutions gear input / Revolutions gear output (P-AXIS-00511/P-AXIS-00512)).

f: Feed constant (0.1µm / Revolution) (P-AXIS-00362/P-AXIS-00363).
