NAHx DATx CRFx FUPx
[Data type] Bit axis
FUPx To perform follow-up when the servo is off is set for each axis.
0 : The follow-up signal, *FLWU, determines whether follow-up is
performed or not.
When *FLWU is 0, follow-up is performed.
When *FLWU is 1, follow-up is not performed.
1 : Follow-up is not performed.
NOTE
When the index table indexing function (M series)
is used, be sure to set FUPx of the 4th axis (index
table indexing axis) to 1.
CRFx When servo alarm No.445 (software disconnection), No.446
(hardware disconnection), No.447 (hardware disconnection (separate
type)), or No.421 (excessive dual position feedback error) is issued:
0 : The reference position setting remains as is.
1 : The system enters the reference position undefined state.
DATx When a manual reference position return operation is performed using
an encoder with absolute address reference marks (linear scale/rotary
encoder)/encoder with distance-coded reference marks (linear
scale/rotary encoder) (detection circuit C), parameter Nos. 1883 and
1884 are:
0 : Not set automatically.
1 : Set automatically.
The procedure for automatic setting is as follows:
<1> Set a proper value in each of parameter Nos. 1815, 1821, and
1882.
* For an encoder with distance-coded reference marks (linear
scale/rotary encoder) (detection circuit C), parameter No.
1882 need not be set.
<2> Position the machine manually at the reference position.
<3> Set this parameter to 1.
<4> Perform a manual reference position return operation. Upon
completion of manual reference position return operation,
parameter Nos. 1883 and 1884 are set, and this parameter is set
to 0 automatically.
NAHx In the advanced preview control mode, advanced preview
feed-forward is:
0 : Used
1 : Not used
NOTE
Set 1 for a PMC-based control axis.
