Which softkey allows you to enter additional program instructions into a TP program?

The softkey that allows you to enter additional program instructions into a TP (Teach Pendant) program is the [INST] key. This key is specifically designed to prompt the operator to add new instructions to an existing program. When pressed, it typically opens a menu or dialog allowing for the insertion of new programming commands or functions, enabling enhancements or adjustments to the original program flow.

Understanding the function of the [INST] key is crucial for efficient programming and modification of tasks within the FANUC system. It facilitates flexibility in programming, allowing users to adapt to changing operational needs or to refine the existing automation sequences. The ability to enter additional instructions enhances the control an operator has over the machine's behavior and can lead to better optimization of tasks.

Each of the other softkeys serves different purposes in the programming interface. The [EDIT] key is used for modifying existing instructions rather than adding new ones, while the [ADD] key might suggest adding new lines but is not the primary means for inserting comprehensive program instructions in FANUC systems. The [INPUT] key typically relates to input data or parameters and is not focused on program instruction entry.
