DESCRIPTION
TITLE
NO.
PAGE
1. General
This enhancement enables you to select any pair for Spindle Synchronous Control out of
1st to 4th spindles(1st to 3rd spindles in case of 18i).
It is available only for serial spindles.
2. Specification
Spindle Synchronous Control realizes spindle synchronization between one master spindle
and one slave spindle.
Spindle rotation phase can be synchronized, too.
Master for each slave is specified in the parameters No.4831 to 4834.
See the reference manuals mentioned on the chapter “9. References” of this document for
other details such as connection.
Restrictions:
- When spindles are in the modes other than spindle mode, for example, Cs or
Rigid Tapping mode, Spindle Synchronous Control cannot be activated.
Be sure that both master and slave spindles are in spindle mode.
- It is impossible to change modes of synchronous controlled spindles. (P/S 194
alarm will occur)
- When 2nd, 3rd or 4th spindle needs to be CNC S commanded master, Multi-
Spindle option is required. (This option is not necessary if it is PMC commanded
master defined by SINDx signals)
