Analog job selec- Both analog input signals
tion: Principle -
-
-
A: Part value 1 for "Base current" input signal:
1. Step = Voltage (V)/0.625 V
2. Part value 1 = Step * 16
Example
1. Step = 6.25 V/0.625 V = 10
2. Part value 1 = 10 * 16 = 160
B: Part value 2 for "Duty cycle" input signal:
3. Step = Voltage (V)/0.625 V
4. Part value 2 = Step
Example
3. Step = 6.25 V/0.625 V = 10
4. Part value 2 = 10
C: Selected job:
5. Job = Part value 1 (A) + Part value 2 (B)
Example
5. 160 (A) + 10 (B) = 170
Analog job selec- IMPORTANT! Both analog input signals
tion: highest -
selectable job -
The highest selectable job is thus:
A: 9.375 V / 0.625 V = 15, 15 * 16 = 240
B: 9.375 V / 0.625 V = 15
C: 240 + 15 = 255
Welding Simula-
tion
Signal X14:2
The "Welding simulation" signal allows a programmed welding path to be simulated; an
arc, wire feed and shielding gas are not required. The digital output signals „Arc stable",
„Main current signal" and „Process active" are set just as if welding was actually being
performed.
TouchSensing
(ROB 5000/ROB
Signal X8:7
5000 OC)
The "Touch sensing" signal can be used to indicate that the tungsten electrode has made
contact with the workpiece (short-circuit between workpiece and electrode).
If the "Touch sensing" signal is set, the control panel on the power source shows "touch".
There will be a voltage of 30 V on the tungsten electrode (current limited to 3 A).
are used to generate a numeric value for the corresponding job
will be in the range 0-10 V
subdivide this range into 16 steps, each of 0.625 V
use the highest step 16 for signal recognition
therefore utilise an effective range of 0 - 9.375 V instead of 0 - 10 V
