operation panels • Operation panel is broken. (CN34 and CN35) are loosened or
disconnected.
• Check whether operation panel cord is
disconnected since the cord is caught
with machine head.
E924 Motor driver failure • Motor driver has broken.
E944 Left needle control impossible • Left needle has shifted from the origin • Check whether the left needle origin
(When LH-4168, or 4188 is selected) during holding it. sensor is broken.
• Left needle has shifted from the origin • Check whether needle bar has shifted
during releasing left needle. from the holding position by the exterior
force.
