4.DESCRIPTION OF PARAMETERS B-64120EN/01
- 110 -
After setting this parameter, be sure to turn off the
power. Note that P/S 0 (power-off request alarm) is
#7 #6 #5 #4 #3 #2 #1 #0
DATx CRFx FUPx
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.
When the index table indexing function (M series)
is used, be sure to set FUPx of the 4th 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 With an encoder with absolute address reference marks (linear scale or
rotary encoder) or encoder with the absolute address zero point (linear
scale or rotary encode), automatic setting of parameter Nos. 1883 and
1884 at the time of a manual reference position return operation is:
0: Not performed.
The automatic setting is performed according to the following steps:
<1> Set appropriate values in parameter Nos. 1815, 1821, and 1882.
* For an encoder with the absolute address zero point (linear
scale or rotary encoder) (detection circuit C), parameter No. 1882
need not be set.
<2> By manual operation, position the machine at the reference
<3> Set this parameter to 1.
<4> Perform a manual reference position return operation. Upon
completion of the manual reference position return operation,
parameter Nos.1883 and 1884 are set, and this parameter is
automatically set to 0.
NAHx In the advanced preview control mode, advanced feed-forward is:
0 : Used
1 : Not used
Set 1 for a PMC-based control axis.
