9.5 ACTUAL SPINDLE SPEED OUTPUT
General
Based on a feedback signal from a position coder mounted on a spindle,
the CNC calculates the spindle speed and outputs it to the PMC.
When a serial spindle is used, the spindle speed can also be calculated
based on the speed monitor data of the spindle motor by setting bit 4
(ASD) of parameter No. 5820.

[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. When a serial spindle is used, the
spindle speed can also be calculated based on the speed monitor data of
the spindle motor by setting bit 4 (ASD) of parameter No. 5820.
This signal consists of 16 binary code output signals. The actual
spindle speed and signal are related as follows:
