MACHINE PARAMETERS

General machine parameters
Bit 13. Use Fagor filters with look-ahead.
Fagor filters always work with the advanced look-ahead algorithm, but they can also be used in the
standard algorithms and with jerk control using this bit 13, in which case, only those Fagor filters
will be used.
If there are Fagor filters defined by machine parameter, set as to eliminate some resonance
frequency of the machine, it will assume the values set in these parameters if their frequency is lower
than those taken by default. Otherwise, it will take the default values of those filters.
Bit 14. Smoother machining.
Activating this bit has the following effects:
• It activates a filter on the machining path.
• It does not limit the speed in very small blocks.
They have an effect when used with advanced or standard algorithm.
Bit 15. It activates the advanced look-ahead algorithm.
This algorithm is recommended by default. It integrates the FAGOR filters.
The following table summarizes the purpose of the bits of general parameter LOOKATYP (P160)
for each type of algorithm:
TLOOK (P161)
Not used
MAINTASF (P162)
This parameter is associated with the MC and TC work modes.
This parameter indicates whether on CNC power-up, the F, S and Smax values are maintained or
initialized to zero.
If the parameter is set to ·1· (maintain the values), the CNC acts as follows on power-up.
• The CNC assumes the G94/G95 feedrate set by general parameter IFEED, but it restores the
F in mm/min (G94) and the F in mm/rev (G95) programmed last.
• It maintains the feedrate type G96/G97 used last, but it restores the S in rev/min (G97) and the
S in m/min (G96) programmed last.
CAXGAIN (P163)
It permits maintaining the proportional gain (FFGAIN) and derivative gain while machining in the
XC and ZC planes. By default, these gains are canceled automatically for smoother machining.

Value Meaning
0 They are initialized with the values of F=0, S=0 and Smax=0.
1 F, S, Smax keep the values of the last machining operation.
Default value: 1
Value Meaning
0 The gains are canceled.
1 The gains are not canceled.
