Current Detection function
Current Detection Signal output function: Parameter “Pr CurDetect” Select (Note 1)
Current Detection Signal sequence (top)………”Pr CurDect ON (Enabled)
With “Pr CurDetect” ON, the Current Detection signal is outputted.
Output conditions: Except for Welding Alarm or No Weld and when the welding current is
Detected.
The Last Step signal from TB1 is not outputted. TP Indication only.
Current Detection Signal sequence (bottom)……”Pr CurDetect” OFF (Disabled)
With “Pr CurDetect” OFF, there is not conduction Detection Signal output.
At this time, when “P8 Step Types” 1 and 2 have been selected (Step Up Enabled), the Last
Step signal is outputted from TB1.
Note 1: With Remote I/O Enabled, terminal block TB1 is used as the remote I/O terminal block.
Therefore, the Current Detection signal is not reaching the terminal block TB1.
Note 2: The Current Detection signal detects the welding current and is outputted based on normal
operation. When Current Alarm or No Weld is detected, the signal is not outputted.
The output timing is approx. 1cyc the HOLD time process starts.
