Err 71.0 Safety function error fault in panasonic drive

Err 71.0 Safety function error fault in panasonic drive means the STO (Safe Torque Off) inputs SF1 and SF2 do not match, or the safety bypass plug is missing.

Cause: The STO (Safe Torque Off) inputs SF1 and SF2 do not match, or the safety bypass plug is missing.

Remedy:

• If not using STO, ensure the factory red bypass connector is inserted in CN X4.
• Check wiring: SF1 and SF2 must switch simultaneously. If one switches and the other doesn't, this error triggers.
