How to Solve ZR ZL MOTOR OVERRUN Error in Splicing Machine [Fujikura 62C+]

1. Welding loss is too large
The cause of this failure can be analyzed from the following points:
(1) The end face of the fiber is not clean and dusty, or there is debris on the V-shaped groove, or there is debris on the fiber holder.
(2) The Angle difference of cutting end face of fiber is too big.
(3) Problems with the optical system, the objective lens problem leads to estimation errors.
(4) Welding strength is not enough or too strong, discharge position deviation.
(5) Fusion splicer program error.
