I have a custom machine with 3 fanuc servos. There are 2 (x12/4000Vis) motors and 1 (x22/4000HVis). The 2 (x12/4000Vis) have absolute pulse coders. I am working on the initial setup for the machine and am having problems setting the Zero Reference Return position (parameter 1815). After setting the APC and APZ bits to 1 and cycling the power, the axis' will not move anymore. No alarms, no nothing. The 2 axis' will jog before I set these bits.
Any ideas as to why this might be happening?
Thanks in advance for any suggestions.
