15503 Filter time constant
[Data type] Word
[Unit of data] msec
[Valid data range] 0 to 32767 (except 1)
[Standard setting value] 0
If tracing becomes unstable as a result of a disturbance such as
mechanical vibration superimposed on the sense signal, set this
parameter to reduce the disturbance.
As a guideline, set a value of no more than 16. If a greater value is set,
the tracing speed response will be lost, thus resulting in problems such
as the nozzle hitting the workpiece upon its approach.
15504 Shift multiplier (EMUL)
[Data type] Word
[Unit of data]
[Valid data range] 1 to 5
[Standard setting value] 1
A multiplier can be applied to the tracing sense signal.
Set value Max. shift Resolution
1 ±2 mm 0.001 mm
2 ±4 mm 0.002 mm
3 ±6 mm 0.003 mm
4 ±8 mm 0.004 mm
5 ±10mm 0.005 mm
15505 TRA
[Data type] Bit
TRA On the trace setting screen, the current position is displayed:
0: In the relative coordinate system.
1: In the absolute coordinate system.
15540 Voltage conversion coefficient of the Z-axis tracing feedrate control
[Data type] Word
[Unit of data]
[Valid data range] 0 to 32767
[Setting] Calculate a conversion coefficient using the following formula, and
set the value thus found.
