Gap-control feed rate (only with gap control
via gap signal)
If the voltage at the analog input is less than the
threshold for the free-run feed rate, the TNC
positions the electrode at the feed rate entered
in this machine parameter, multiplied by a
factor from the PLC.
MP2142
1 to 99.9 [mm/min]
External data transfer
Control character for end of file MP5010
Control character for end of text (e.g., MP 5010=3: EXT): ASCII character
Do not send control character for end of text: 0
Control character for end of transmission MP5011
Control character for end of text (e.g., MP 5011=4: EOT): ASCII character
Do not send control character for end of transmission: 0
Adapt TNC interface to an external device MP5020
7 data bits (ASCII code, 8th bit = parity): +0
8 data bits (ASCII code, 9th bit = parity): +1
Block Check Character (BCC) any: +0
Block Check Character (BCC) control character not permitted: +2
Transmission stop through RTS active: +4
Transmission stop through RTS inactive: +0
Transmission stop through DC3 active: +8
Transmission stop through DC3 inactive: +0
Character parity even: +0
Character parity odd: +16
Character parity not desired: +0
Character parity desired: +32
2 stop bits: +64
1 stop bit: +128
Example:
Use the following setting to adjust the TNC interface to an external non-
HEIDENHAIN device:
8 data bits, any BCC, transmission stop through DC3, even character
parity, character parity desired, 2 stop bits
Input value:
1+0+8+0+32+64 = 105 (input value for MP5020)
Parity setting for LSV-2 protocol MP5100
No parity: 0
Even parity: 1
Odd parity: 2
