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.

[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.
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
