14.3.15 Spindle gear changing and Spindle integrated with C axis control

The spindle changing for the spindle gear changing or the spindle/C axis changing under the

spindle integrated C axis control is permitted via the spindle drive by the command from

PLC according to the spindle parameter changing specification of YS 840DI system specifi-

cation.

Parameter changing to H gear, M gear, L gear, or C axis is initiated by PLC when PLC veri-

fys the request for the parameter selection status number (DBX21.0 - 2) sent from PLC to

CNC and also the completion of changing the parameter selection status number (DBX93.0

- 2) from CNC to PLC. For the parameter changing, the parameter selection number in rela-

tion with each gear selection and C axis selection, and a skeleton time chart is shown below.

Note: If you do not use the gear changing or C axis control, select H gear.
