9.6 SPINDLE SPEED CLAMP (G92)
With the following command, a maximum spindle speed can be set:
G92 S_; (where S_: Maximum spindle speed in min
-1
)
A set maximum spindle speed is output to the PMC as a 16-bit binary
code. On the PMC, the spindle speed needs to be clamped according to
the output maximum spindle speed.
Whether the S command specified in a block in which G92 is specified
is to be regarded as a command for specifying a maximum spindle
speed can be chosen by parameter setting.
9.7 ACTUAL SPINDLE SPEED OUTPUT
An actual spindle speed calculated using a feedback signal from the
position coder attached to the spindle is output to the PMC as a 16-bit
binary code. With a serial spindle, a spindle speed can also be
calculated from the spindle motor speed monitor data.
