Ineed to enable PWE in Fanuc Oitb system to alter the feed rate parameters. Can someone help me?. THe PWE enable is write protected via PLC. It is enabled if the edit key is On and F72.0 and F72.1 is on. This F bits are CNC-PLC signals and are user defined. Futher there is a Keep relay K8.6 in parallel to bypass PWE. But even this keeprelay can be set only if PWE is enabled.
How to force the F bits to active state.
