TNC 407/TNC 415/TNC 425 3 Software 2-19
TNC 407: 243 03x 05 Release 11/92
New functions:
All functions as for TNC 415 B except "Working Plane" cycle and three-dimensional tool compensation.
TNC 415 B/TNC 425: 259 93x 06
TNC 415 F/TNC 425 E: 259 94x 06
TNC 407: 243 03x 06 Release 12/92
New functions:
−
MP7411 is used to select whether to use the tool data (length, radius, axis) from the last TOOL
CALL block or from the calibrated data of the probe system in a touch probe block.
−
MP7411 Tool data in touch probe block
Entry: 0 or 1
0 =In the touch probe block the current tool data are overwritten with the
calibrated data of the probe system.
1 =Current tool data are retained even with a touch probe block.
−
The displayable area for FK graphics has been restricted to -30,000 mm to + 30,000 mm. The
maximum edge length is 30,000 mm.

TNC 407 243 03X 07 Release 3/93
New functions:
−
PLC module 9033 has been introduced. This module allows the user to select a particular machine
parameter file in a SUBMIT job and then execute a Reset so the control system boots up with this
MP file.
−
If the PLC simultaneously issues two commands from memory areas PLC positioning (M2704 to
M2708), confirm Q parameter (M2713) and PLC datum shift (M2716), then the NC flashes the
message "Error in PLC program 1R" as these commands use the same memory areas for data
transfer.
−
PLC positioning in more than one axis counts as a single command. If marker M2719 (switch-over
from word processing to TNC 355 mode) has the value 0, the same checks will be run with the
corresponding TNC 355 strobes.
−
The offset for a variable-speed spindle is now adjusted with a new algorithm. A single offset
adjustment is made two seconds after the nominal value has reached target position. Every
second thereafter the offset voltage is increased by 0.152 mV or decreased by 0.152 mV when
servo lag is greater or less than zero respectively, and if the voltage computed from the product of
servo lag and Kv factor is greater than 0.152 mV. This means that the offset voltage changes by 1
mV in 7 seconds approx.
