4. DESCRIPTION OF PARAMETERS
B–64160EN/01
64
APCx Position detector
0 : Other than absolute position detector
1 : Absolute position detector (absolute pulse coder)
For an absolute–position system using Inductosyn, set this parameter to 1.
#7
1817
#6
TANx
#5 #4
SCPx
#3 #2 #1 #0
NOTE
When this parameter has been set, the power must be
turned off before operation is continued.
[Data type] Bit axis
SCPx If bit 2 (DC2) of parameter No. 1802 is set to 1, the scale zero point of the
linear scale with absolute addressing reference marks is:
0: On the negative direction side. (Viewed from the scale zero point, the
reference position is on the positive direction side.)
1: On the positive direction side. (Viewed from the scale zero point, the
reference position is on the negative direction side.)
TANx Tandem control
0 : Not used
1 : Used
NOTE
Set this parameter to both master axis and slave axis.
#7
1819
#6 #5 #4 #3 #2 #1
CRFx
#0
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.
