TNC406/TNC 306 Update Information No. 11
1-5
• New soft key under code number 98 148
The new soft key "SETUP COLORS" enables you to adjust the colors red, green, and blue in the
machine parameter for the respective color. You can mix the colors for foreground and
background separately and accept the change with ENT. Pressing END terminates without
changing the color.
• Change in reading the analog input for gap control
The digital sampling rate of the analog input is now 1 or 0.5 ms, i.e., each time four analog values
are read and the mean value is used in the following control loop cycle (4/2 ms). This makes it
possible to acquire input frequencies up to max. 250 / 500 Hz.
• TOUCH-PROBE functions
If M36 is active when the TOUCH PROBE cycle is executed, M37 is output automatically
(erosion switched off). The selection of the TOUCH PROBE functions was assigned to soft keys.
The datum number can be entered directly in the TOUCH PROBE basic menu. This eliminates
the need to make the datum selection beforehand through Q80.
• Output of a step function for machine adjustment
Under the code number 105296 the output of a step function can be activated. The issued step,
activated over the OUTPUT STEP soft key, is adjustable in amplitude (voltage or feed rate) and
pulse duration through the arrow keys. The axis is selected by axis key. The step function makes
it possible to best adjust the servo amplifier and define the values for acceleration and Kv.
• Output of dialogs
Under the code number 105 296 it is possible to activate the output of dialogs. The following
control dialogs can be output in the adjusted language with the corresponding dialog number
through the RS-232 port under NAME.CNC (in connection with TNC.EXE):
all NC control dialogs
DIA:
all NC error messages ERR:
all dialogs of the table editor TAB:
all PLC dialogs from PLC chip PLC:
all cycle dialogs from PLC chip CYC:
This makes it possible, for example, to proofread the control dialogs and the dialogs on the PLC
chip for correctness of translation and spelling.
• Output of analog values
On connector X8, pin 8 you can output the analog values by selecting the code number 79 513
and the function SELECT SOURCE FOR ANALOG OUTPUT.
The following analog values are selectable:
1. Analog value from PLC word 524, value in mV (default setting)
2. Actual velocity of the selected axis (derived from the actual position value)
3. Servo lag of the selected axis
4. Nominal velocity (analog output) of the axis
5. Reference input variable of the axis (derived from the nominal position value)
6. Erosion velocity of the axis
The analog values can also be output during execution.
