MP2052 Advanced switch-on distance for reapproach;
After timing (M2780=1), the oscillator signal of the
generator can be switch on earlier. In this way the
control receives a correct analog gap signal during
the transition from positioning to gap control.
Entry range: 0 to 2 [mm] –
MP2060 Infeed rate when eroding on (M36) and marker
M2620 is set
Entry range: 1 to 500 [mm/min]
Removed in TNC 406 as of software 280 620-07.
If the function is needed for special applications,
you can use MP2081=1 to realize a two-position
control without characteristic curve. An other
possibility: The threshold for free-run feed rate
from MP2141 can be defined with W520 (0..500).
123 4–60
MP2070 Feed rate at maximum gap voltage (5V) and
MP 2020 = 1 and MP 2030 = 1;
Calibration of input characteristic
Entry range: 1 to 3000 [mm/min] 4–57
MP2080 Gap signal input
Entry range: 0 to 2
0 =
Not inverted
1 = Inverted
2 = Analog input from spindle potentiometer
(for testing purposes only)
4–56
MP2081 Selection of gap control
Entry range: 0 or 1
0 = Analog input is velocity signal
1 = Analog input is gap signal –
MP2090 Speed for a non-controlled rotary axis (M3/M4)
Entry range: 1 to 100 [rpm] 123 4-54
MP2100 Editing possible in defined positions of eroding

Entry value: 0 to 255 –
MP2110 Delay of "spark-out is completed" signal (marker
M2616)
