− 20 −
Full-closed loop
Reference counter
setting
=
Z-phase (reference-position) interval divided by
the detection unit, or this value sub-divided by an
integer value
Example of setting
Example 1) When the Z-phase interval is 50 mm and the detection
unit is 1 µm:
Reference counter setting = 50,000/1 = 50,000
Example 2) When a rotation axis is used and the detection unit is
0.001°:
Reference counter setting = 360/0.001 = 360,000
Example 3) When a linear scale is used and a single Z phase exists:
Set the reference counter to 10000, 50000, or another
round number.
(11) When using an S-series amplifier, set the following parameters:
#7 #6 #5 #4 #3 #2 #1 #0
1809 8X04 DLY1 DLY0 TIB1 TIB2 TRW1 TRW0 TIB0 TIA0
2004 1004 01000110
(↑ S-series amplifier)
1866 8X54 Current dead band compensation (PDDP)
2054 1054
Set value 3787 (S-series amplifier)
CAUTION
In rotation axis control for the Series 16, 18, and
Power Mate, continuous revolution in the same
direction will result in an error if the result of the
following calculation is other than an integer, even if
the reference counter setting is an integer. Therefore,
set parameter No. 1260 so that the result of the
calculation is an integer.
