In FANUC programming, what does the command RAMP control?

The command RAMP in FANUC programming is used to control the acceleration and deceleration rates of the machine's movements. This feature is critical for ensuring smooth operation and minimizing mechanical stress on the machine. By managing how quickly a machine accelerates to its target speed or decelerates to stop, RAMP can help achieve precise motion control.

Effective ramping is essential in applications where sharp movements could lead to vibrations or instability. This control allows for improved accuracy in machining operations, enhancing the quality of the final product while preserving the integrity of the machinery.

The other options, while related to machine operation, do not accurately describe the function of RAMP. For instance, rotation speed relates more to spindle or motor performance but does not directly involve the scaling of motion, as RAMP does. Command execution time pertains to how quickly a program runs commands, which is separate from the dynamic control of speed changes. Power supply levels correspond to the electrical input but are not influenced by RAMP settings.
