9. SPINDLE SPEED FUNCTION

The command system comes in two types: The first positions a semi-fixed
angle; the second positions an optional angle.
A 2-digit numerical value following the M address is used for the
command. There are six positioning angle values (Mα to M(a + 5)),
wherea is set by parameter No. 4962. Indexing angle
β also requires prior
parameter setting data No. 4963. Rotation can be done in any direction,
using parameter IDM data No. 4950#1.
Also, when extended specification is used (parameter No. 4950#6
ESI=1), max. 256 kinds of values (Ma to M(a+255)) can be specified.
M–code Indexing angle eg) when b=30_
Mα β 30°
M (α+1) 2β 60°
M (α+2) 3β 90°
M (α+3) 4β 120°
M (α+4) 5β 150°
M (α+5) 6β 180°
Numerical value following either the C or H address is used to command
the position. C and H addresses are commanded in G00 mode.
(Example) C-1000
H4500
(i) Minimum setting unit :
0.001deg
(ii) Maximum command value:
"9999.999 deg
(iii) Decimal point input: A numerical value with decimal point can be
entered. The decimal point location is in “degrees”, for instance:
C35.0=C35 degrees
