NOTE
When the flexble feed gear is used, do not use these
parameters. Set the numerator and denominator of DMR to
an appropriate values in parameters 2084 and 2085
respectively.

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 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.
NAHx In the look–ahead control mode, advanced feed–forward is:
0 : Used
1 : Not used
NOTE
Set1 for a PMC–based control axis.
1820 Command multiplier for each axis (CMR)
NOTE
When this parameter has been set, the power must be
turned off before operation is continued.
[Data type] Byte axis
Set a command multiplier indicating the ratio of the least command
increment to the detection unit for each axis.
Least command increment = detection unit command multiplier
Relationship between the increment system and the least command
increment
