Coded output of
spindle speed
1572
Use the parameter MP_sCode to configure a word marker for the coded
output of the spindle speed (S code). You must output the speed code to the
spindle drive through PLC outputs.
If the speed code is changed, the NC sets the S strobe. If you acknowledge
the S code with the marker defined in MP_acknowledge, the NC program is
continued and the S strobe is reset by the NC.
If required, the programmed spindle speed is rounded off to the next standard
value by the NC and given in S code as per DIN 66025 (see the S-code table
below).
Speeds of 0 to 9000 min
 Use the machine parameter MP_sCode to define a symbolic name or the
number of a word marker, in which the S code of the spindle speed is
transmitted to the PLC.
