TNC 406/TNC 306 Update Information No. 11 3/97
The new software version 5 of TNC 406 introduces the following new features:
• Machine parameters MP7470 and MP7274 are axis-specific
The MPs 7470.0 and 7274.0 are assigned to the 4th axis (MP410).
The MPs 7470.1 and 7274.1 are assigned to the 5th axis(MP411).
• New machine parameter MP2052 for advanced switch-on distance
Input value = 0...2.0 [mm]
In MP2052 you can enter an advanced switch-on distance. This makes it possible to switch on
the oscillator signal of the generator earlier during workpiece reapproach after timing (marker
M2780). The control then receives a correct analog gap signal during the transition from
positioning to gap control.
• New machine parameter MP7241 for the NC blocks EL CALL and WP CALL
(See below for description of EL CALL and WP CALL)
Input value = 0 NC blocks disabled
= 1 NC blocks enabled
• New machine parameter MP2081 for gap control
Input value = 0 Analog input corresponds to the velocity signal (previous type of gap control)
= 1 Analog input corresponds to the gap signal (new type of gap control)
• New machine parameter MP5200 for the baud rate of the RS-422 interface
Input value = 0 baud rate is 9 600
= 1 baud rate is 38 400
• New machine parameter MP7232
Input value = 0 Disable OEM fonts display
= 1 to 9 Enable OEM-Fonts display, the number sets the distance in pixels
between any 2 characters on the screen
• Machine parameter MP5030 (baud rate after reset) was canceled. After reset the baud rate is
always 9600.
• The input range for MP 1060.x (accelerations) was changed to 0.01 ... 9.0.
• The input range for MP 330.x (resolution of encoder) was changed to 1 to 360 [µm or 1/1000
degrees] per encoder signal period.
For more information see above description of new features for TNC 306.
• New PLC word D400
D400 = angle of rotation (basic rotation)
• New marker M2189
If a PLC error message is displayed (one or more error markers 2924 and following is set), then
marker M2189 is set. PLC error messages are erased after the error message is reset or by
pressing the CE key.
