What to do if Fronius VR 1500 Wire Feeders show Err | 056?

S
Shawn WilcoxOct 30, 2025
If your Fronius Wire Feeders display error code Err | 056, it could be due to several reasons: * The wire end check option has detected the end of the welding wire. In this case, insert a new wire spool, thread in the welding wire, and acknowledge the error on the power source. * The additional fan filter is contaminated, restricting airflow and causing the power electronics temperature switch to trip. Clean or replace the filter and then acknowledge the error on the power source. * The ambient temperature is too high. Reduce the ambient temperature, or move the welding system to a cooler location, then acknowledge the error. * The motor current is too high, possibly due to wire threading problems or an inadequately dimensioned wire feeder. Check the wire threading conditions, rec...
