Offizielle Schritte zur Fehlerbehebung
Details The command for the pitch or the number of threads is not correct in the synchron ous tapping command of the multiple-spindle control II. The pitch is too small for the spindle rotation speed. Thread number is too large for the spindle rotation speed. Remedy Correct the pitch, number of threads or rotation speed of the tapping spindle. Wait for tap retract 0057 Details The axis travel command is interlocked as the tap retract is being enabled. Remedy If tapping is necessary, perform tapping retract in ad vance. However, tapping retract is not allowed during cycle start operation. Carry out tapping retract after resetting. If tapping is not necessary, cancel the tap retract en abled condition by the tap retract enabled cancel sig- nal. Handle ratio too large 0060 Details The handle ratio is too large for the handle feed clamp speed. (The handle feed clamp speed changes according to the rapid traverse rate, external feedrate, maximum speed outside the soft limit range and etc. (or external deceleration speed when external deceleration is valid)) Too large handle ratio means the ratio with which the mach ine is unable to move the distance of [iunit * handle ratio] within 0.1ms at the clamp speed. Example) When iunit=B (0.001mm) a nd clamp speed cs (mm/min) The operation error (M01 0060) will occur if ratio M>cs/60(s)*0.1(ms )/0.001(mm)=cs*10/6. Remedy Change the settings of the handle fe ed clamp speed or the handle ratio. R-pos offset value illegal 0065 Details At the start of reference position initial setting, the parameter "#2034 rfpofs" (Dis tance-coded reference position detection offset) is not set to "0". Remedy Set the parameter "#2034 rfpofs" to "0", then turn the power ON again to perform the reference position initial setting. R-pos scan distance exceeded 0066 Details Reference position could not be estab lished within the maximum scan distance. Remedy Check the scale to see if it has dirt or damage. Check if the servo drive unit supports this function. Illegal op in wk instl err cmp 0070 Details One of the following operations was attempted du ring workpiece installation error compensation. Manual interruption Automatic operation handle interruption MDI interruption PLC interruption Remedy Return the operation mode to the original mode to remove the cause. During workpiece installation error compensation, manual interruption, automatic operation handle interruption, MDI interruption, PLC inter- ruption, etc. is not allowed.
