11.7 ACTUAL SPINDLE SPEED OUTPUT
Overview
The PMC can read actual spindle speed.
Signal
Actual spindle speed signals AR00 to AR15<Fn040,Fn041> : First spindle
AR002 to AR152<Fn202,Fn203> : Second spindle
AR003 to AR153<Fn206,Fn207> : Third spindle
AR004 to AR154<Fn272,Fn273> : Fourth spindle
[Classification] Output signal
[Function] These 16-bit binary code signals output from the CNC to the PMC the
actual spindle speed obtained by feedback pulses from the position
coder mounted on the spindle.
[Output condition] These 16-bit binary code signals are always output. The actual
spindle speed and the signals have the following relationship:

Note
NOTE
An absolute error of about 0.5 min
-1
exists as a
measuring error.
If the speed exceeds 65535min
-1
, 65535 is
assumed and output.
