- Selecting a spindle to be controlled
When there are two or more spindles, you must select a spindle that is
currently controlled by the CNC.
The spindle to be controlled is:
(1) Spindle for which the spindle speed is displayed on a screen such
as the position display screen or program check screen.
(2) Target spindle for an S command, threading, feed per revolution,
constant surface speed control, rigid tapping, canned cycle,
spindle speed fluctuation detection, and so forth.
Set the spindle number of a spindle to be controlled in parameter No.
5850.
CAUTION
Before rewriting this parameter during automatic
operation, always use the M code set in parameter
Nos. 2411 to 2420 which is used as a non-buffering
M code. Always rewrite the parameter in the non-
buffering state.
- Differences in controlling spindle control units
When controlling the spindle control units directly, there are
differences between spindle serial output and spindle analog output, as
follows:
Spindle control unit for spindle serial
output interface
Spindle control unit for spindle analog output
interface
