Never enter PARAM and then press OUTPUT unless you have a proper RS-232 connection. You can inadvertently send garbage data to the control.
A deep understanding of your 11M's parameters is not a luxury—it is a necessity for its survival. This guide provides the essential map for navigating this complex system. The most critical takeaway is this: fanuc 11m parameter list
11 = 9600 Baud (Most recommended for stability on older hardware) 12 = 19200 Baud Axis Control & Servo Configuration Never enter PARAM and then press OUTPUT unless
: Stored stroke limits (Soft overtravel limits). Temporary adjustment to 99999999 can suppress overtravel alarms during maintenance. Parameter 1420 : Rapid Traverse Rate for each axis. Parameter 3741–3743 : Maximum spindle speed limits. This guide provides the essential map for navigating
Determines the Baud Rate for data transmission. Common values include: 9 = 2400 Baud 10 = 4800 Baud
Many operational issues on an 11M can be traced back to a simple parameter oversight.
