When your production line is halted, you need answers fast. Below are the most common questions we receive regarding the Fanuc SVM1-40i and the A06B-6240-H105 replacement process, designed to help you make a quick and informed decision.
| FAQ | Answer |
|---|---|
| Does the A06B-6240-H105 require programming? | No. The drive parameters are stored within the CNC control itself, not the amplifier. However, you may need to verify the FSSB ID setting (rotary switch) matches your old unit before installation to ensure proper communication. |
| What is the difference between SVM1-40i and Type B? | The difference typically lies in the mounting interface or connector configuration (such as the CXA2A/B ports). Always check your specific part number to ensure the physical fit matches your electrical cabinet. |
| Do you offer rush shipping? | Yes. We know that downtime costs money. We ship globally via express carriers like DHL, FedEx, and UPS to get your Fanuc Alpha i Servo Amplifier to you as quickly as possible. |
