Monitoring of Motor Current

The motor current of rotating feeding motor can be displayed in the 7-segment LED indicator
"Wire m/min" by setting D parameter D1-5 to "OFF". During the standby status, the 7-seg-
ment LED indicator displays the command of wire feeding amount (m/min).
V
When the 7-segment LED indicator displays the motor current, "A" is indicated at the third digit
of the indicator.
In the figure above, the motor current is 0.5 A.
When the 7-segment LED indicator does not display "A" at the third digit, D parameter D1-5 is
set to "ON" status, and the indicator shows the feedback speed of wire feeding.
There are two levels for monitoring the motor current: the warning level and the error level.
• Motor current warning
Outputs a warning signal when the motor current exceeds the warning level which has
been set by C parameter C25. Wire feeding and welding will be continued although the
motor current exceeds the warning level. The warning signal will be output through the
terminals 524 and 525 on the Pr(RC2)-001 board.
• Motor current error
Outputs Err502 "motor overcurrent" and ends wire feeding and welding when the motor
current is passed more than the rated current.

System Reset
System Reset initializes all the setting data in the welding source. Reset the system only when
the software is updated or initialization or when Memory Error (Error 205 to 299) occurs.
• Be sure that executing System Reset initializes all the internal data.
If some parameters must be retained, write them down on a sheet of
paper before System Reset. The data cannot be restored after the sys-
tem reset operation.
