DIGITAL SERVO B–62755EN/01PRM1850 Grid shift amount per axis [P]When the resolution is 0.0001mm, set the value in the unit ten timesthe detection unit.PRM1815#7#6 #5APC#4APZ#3 #2 #1OPT#0#5(APC)0 : Position detector is other than absolute pulse coder.1 : Position detector is absolute pulse coder.#4(APZ) Zero position of absolute pulse coder is :#1(OPT)0 : Not established1 : Established(Turns to 1 after establishment)To manually change the value of the APZ bit from 0 to 1 without firstreturning to the reference positionwhen using serial pulse coder α , follow this procedure: Back up thedata with the battery and give the motor one or more turns.Turn the power off then on again, then change the APZ bit settingfrom 0 to 1.0 : Position detection is performed by the pulse coder built in the motor.1 : Separate type pulse coder or linear scale is used. Separate Type PulseCoder or Linear Scale isUsedPRM1821 Reference counter capacity per axis [P]Normally, the number of feedback pulses per motor revolution is set tothe reference counter capacity.When plural reference marks are on a linear scale, a quotient of thedistance between the reference marks divided by an interfer may be usedas a reference counter capacity:Example)(1µ m)300mm ⇒ reference counter 30000200001500010000 etc258
