Frequently Asked Questions

Can I test a Fanuc control system without removing it from the machine?

In most cases, no. Accurate testing typically requires removing the suspect unit and connecting it to a dedicated Fanuc CNC test system. These systems simulate real-world operating conditions that the machine alone can’t replicate during a fault state.

What’s the difference between testing a Fanuc control and testing a drive?

Testing a Fanuc CNC control involves verifying program execution, I/O communication, and system functions such as alarms and displays. Testing a drive (servo or spindle) focuses on power electronics, amplifier signals, motor feedback, and fault codes. Both require different test benches and diagnostic tools.

How do I know if the issue is with my control or the I/O module?

That’s exactly what a test system helps determine. Swapping components in a test environment isolates faults to the control, I/O module, or cabling. Without test systems, you risk swapping the wrong part and compounding the issue.
