Example Of How To Program Gwps - Siemens SINUMERIK 840D sl Function Manual

Programming
The spindle speed can be modified through the input of a grinding wheel peripheral speed.
The spindle speed can be modified through:
● programming in the part program/overstoring
● programming the grinding wheel peripheral speed through assignment to address "S" in
● spindle speed control via PLC (FC18).
DB31, ... DBX84.0 (GWPS active)
Interface signal:
DB31, ... DBX84.0 (GWPS active)
can be used to determine whether or not GWPS is active.
