When this encoder breaks,
On the lathe, there are the following possible failures:
1 The spindle speed is not displayed or is inaccurate.
2 G01 cannot go, but G0 can go.
3 G32 thread command is not executed.
On the machining center, there are the following possible failures:
1 M19 positioning cannot be completed.
2 Rigid tapping cannot be completed.
Sometimes, for current operation and judgment, we can change parameter 4002.1 (SSTYP1) to 0 to shield the fault. 4002 parameters are defined in the following table:
