Why does my Sourcetronic ST500 show Err.07?
- RRobert ReeseSep 4, 2025
Your Sourcetronic DC Drive might display Err.07 if there's an external force dragging the motor while it's running; in that case, cancel the external force or install a braking resistor. The error can also be caused by a high input voltage, so set the voltage to the normal range.
