1974 8X81 Dual position feedback zero-point amplitude
2081 1081
[Setting value] Zero width (µm)/minimum detection unit for full-closed mode
[Increment system] Minimum detection unit (µm/p) for full-closed mode
Positioning is performed so that the difference in the position between
full-closed mode and semi-closed mode does not exceed the pulse
width that corresponds to the parameter-set value.
First set the parameter to 0. If still there is fluctuation, increase the
parameter value.
If this is applied to an axis with a large backlash, a large positional
deviation may remain. For details, see Art. (5) in this section.

Dual position feedback: Level on which the difference in error between the
semi-closed and full-closed modes becomes too large
[Setting value] Level on which the difference in error is too large (µm)/minimum
detection unit for full-closed mode
[Increment system] Minimum detection unit (µm/p) for full-closed mode
If the difference between the pulse coder and the separate detector is
greater than or equal to the number of pulses that corresponds to the
value specified by the parameter, an alarm is issued.
Set a value two to three times as large as the backlash.
When 0 is set, detection is disabled.

HBBL (#5) The backlash compensation is added to the error count of:
1: The closed loop.
0: The semi-closed loop. (Standard setting)
HBPE (#4) The pitch error compensation is added to the error count of:
1: The semi-closed loop.
0: The closed loop. (Standard setting)

HBFS (#4) A backlash compensation and pitch error compensation are:
1: Added to the closed loop side and semi-closed loop side at the
same time.
0: Added after selection according to the conventional parameter
(No. 2010 (Series 16, 18) or No. 1954 (Series 15)).
When this parameter is set to 1, the settings of No. 2010 (Series 16,
18) and No. 1954 (Series 15) are ignored.
