Zero point adjustment
Set a zero point with the trace setting screen.
Repeat the following operation a few times to check that there is no
significant setting variation (within about ±320).
Select the trace setting
screen.
Move the nozzle towards the
workpiece using manual
operation.
Press soft key [ZERO POINT].
Setting is
complete.
Is the nozzle
positioned at the standard
reference position ?
NO
YES
Shift calculation formula
When the above adjustments are made, the CNC calculates the amount
of shift DE by means of the following formula.
∆E= (Ke×E-Ezr)×Emul
where,
∆E: Calculated amount of shift
Ke: Sensing gain coefficient (determined by the above
operation and set in parameter No. 15500)
E: Sense level read from the A/D converter
Ezr: Amount of zero adjustment (determined by the above
operation and set in parameter No. 15502)
Emul: Value set in parameter No. 15504
- Tracing gain adjustment procedure
Tracing gain is a parameter that determines the tracking capability of
tracing. The tracking speed (Vz) of tracing is determined from the
formula below.
Vz=60×K×(∆E-E0)
where,
Vz: Tracking speed (mm/min)
K: Tracking speed voltage conversion coefficient
∆E: Amount of shift (mm)
E0: Standard shift (mm)
