block
MP2040
0.1 to 10
Advanced stop distance after short circuit or
CYCL STOP
After a short circuit or CYCL STOP block, the
TNC moves the electrode back towards the
workpiece, but stops at a certain distance from
the workpiece. This distance is entered in
MP2050.
MP2050
0 to 2 [mm]
Advanced stop distance after flushing
After flushing the electrode gap, the TNC
moves the electrode back towards the
workpiece, but stops at a certain distance from
the workpiece. This distance is entered in
MP2051.
MP2051
0 to 2 [mm]
Advanced stop for oscillator signal
At the end of a programmed eroding time, the
TNC moves the electrode back towards the
workpiece. When the electrode reaches the
distance from the workpiece that was entered
in MP2052, the TNC reactivates the oscillator
signal of the generator. This ensures that the
TNC always receives the correct analog gap
signal when switching from positioning to gap
control.
MP2052
0 to 2 [mm]
Rotational speed of the C axis with M3/M4
When M3 or M4 are programmed, the C axis
rotates at the speed entered in this user
parameter.
MP2090
0 to 100 [rpm]
Duration of the free run signal after eroding
The duration of the free run signal when the
programmed eroding step is completed is
determined in this user parameter.
MP2110
0.1 to 99.9 [s]
Arc detection
The TNC recognizes an arc that exists as long
as defined in this user parameter.
MP2120
1 to 99.9 [s]
Free-run feed rate (only with gap control via
gap signal)
If the voltage at the analog input is greater than
the threshold for the free-run feed rate, the
TNC positions the electrode at the feed rate
entered in this machine parameter.
MP2141
0 to 3000 [mm/min]
