TROUBLESHOOTING FOR KNIFE REPLACING
When the system uses electric turret knife rack, the knife replacing will fail if the parameter setting
isn’t proper, for example, can’t replace the knife. Please check whether the knife number is set to 0,
whether the maximum knife replacing time is reasonable, and whether the settings of connection and
jumper of knife rack signal conversion board are proper. These settings can be checked in the
diagnosis interface. Please reduce the range to eliminate the fault.
