Spindle speed override for each spindle
(Improvement of multi-spindle)
Sheet

1.General
During this function, each spindle speed can be overridden individually. An override value to 0%~254% can be applied. This
function can be used when multi-spindle control type C (parameter MSC (No.3713#3)) is set.
This function requires multi-spindle control option.
2.Specification
When each spindle speed override function (parameter EOV(No.3713#4) =1) is effective, the specifications is as following.
- Override signals for each spindle are following.
SOV0~7: Override signal for first spindle
SOV20~27: Override signal for second spindle
SOV30~37: Override signal for third spindle
SOV40~47: Override signal for fourth spindle
- Each spindle speed can be overridden individually because an independent override can be applied to each spindle.
And, in the case of spindle control on multi path, each spindle speed can be overridden by this function, too. Below figures
are example when spindles of both paths are connected to path 2.
