1850 Grid shift amount per axis [P]PRM
* This parameter is set using a value ten times the unit of
detection, if the input system uses units of 0.0001 mm.
#7 #6 #5 #4 #3 #2 #1 #0
1815 APC APZ OPTPRM
#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:
0 : Not established
1 : Established
(Turns to 1 after establishment)
To manually change the value of the APZ bit from 0 to
1 without first returning to the reference position when
using serial pulse coder α , follow this procedure: Back
up the data with the battery and give the motor one or
more turns.
Turn the power off then on again, then change the APZ
bit setting from 0 to 1.
#1(OPT) 0 : The pulse coder built into the motor is used for position
detection.
1 : A separate pulse coder or linear scale is used for
position detection.
1821 Reference counter capacity per axis [P]
PRM
Normally, the number of feedback pulses per motor revolution is set to
the reference counter capacity.
When plural reference marks are on a linear scale, a quotient of the
distance between the reference marks divided by an interfer may be used
as a reference counter capacity:
Example)
(1µ m)
300mm ⇒ reference counter 30000
20000
15000
10000 etc
