W4: Grinding-specific tool offset and tool monitoring
17.5 Constant grinding wheel peripheral speed (GWPS).
Extended Functions
832 Function Manual, 03/2013, 6FC5397-1BP40-3BA1
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
MDA
● spindle speed control via PLC (FC18).
DB31, ... DBX84.0 (GWPS active)
The following interface signal can be used to determine whether or not the GWPS is active:
DB31, ... DBX84.0 (GWPS active)
