Using the FANUC controller power cycle via the iPendant minimizes the risk of damaging the controller's PCBs.

• A. True
• B. Only during maintenance
• C. Depends on model
• D. False

Answer: (A)

Power cycling via the iPendant triggers a controlled shutdown and restart within the FANUC controller. This ensures the controller enters a safe state before power is removed and re-applied, with servo drives properly disabled and any in-progress I/O operations concluded. The system then reinitializes from a known state when power returns, reducing the chance of voltage spikes, latch-ups, or corrupted memory that can occur with abrupt power cuts. By coordinating the reset through the pendant, you minimize risk to the controller’s PCBs, making this the safer choice.
