Official Troubleshooting Steps
Details Phase-Z detection speed has not been set in "#3109 zdetspd". Remedy Set the phase-Z detection speed in "#3109 zdetspd". Intrf chck across sys: Set err 1050 Details Setting of Interference check ac ross part systems is incorrect. Remedy Correct the setting of Interfer ence check across part systems. Intrf chck across sys: Area AL 1051 Details Interference is already occurring on the set interfering object. Remedy Turn OFF the interference check valid signal, moving the axis to a position where the interfering objects do not collide each other, and then rest art Interference check across part systems. Intrf check across sys: Alarm 1052 Details A command has been given that causes the interfering objects to collide each other. Remedy Correct the program.
