After having studied the way of correcting a looping error on an axis, we shall now deal with overcoming a looping error on a spindle.

Type of error:
Several types of looping error messages may appear during spindle programming. Message G1017 is displayed in the dialog box and a text in brackets then specifies the type of fault.

1. Looping error when running at speed
A looping error when running at speed means that the effective spindle speed (number of revolutions per minute) at the start of the loop (G13) is not the same as at the end of the loop (G113). In such cases the following message is displayed: G1017: Looping error on spindle S1 (Speed)

2. Mode-related looping error
A looping error related to mode is detected when the spindle is not in the same mode at the start of the loop (G13) as at the end of the loop (G113). The different spindle modes could be as follows:

  • speed mode (programmed revolutions per minute)
  • synchronous mode with another spindle (M?18)
  • polygon mode (G?51)
  • axis C mode (M?98).
The following message then appears, for example, if there is a synchronisation fault:

G1017: Looping error on spindle S4 (M?18)

errorUse the spindle resources line.

Display the resources line of the spindle involved in the fault and observe the curve showing changes in speed or mode.

To display a resources line, proceed as follows:

Using the left button of your mouse, click on the top of the operations line (1) and without releasing your mouse, drag this line down to the bottom of the screen. In this newly created line you can by clicking the right button of your mouse create a resources display for one axis and/or one spindle.

Tip :
Unlike the looping error on an axis, one cannot detect the looping error on a spindle using "single mode". However, the following tips will allow quick detection of the type of looping error and provide the pertinent correction.
