Upgrading an A800

Disassembly & Installation

1. Unplug the cat5 cable going into the VFD and remove the 2 screws holding on the bottom cover.

2. Once the screws are loosened (they will not come out all the way out) gently pull up from the bottom of the cover to remove it.

3. Loosen the 1 screw holding in the top cover.

4. Once the screws are loosened (they will not come out all the way out) gently pull up from the bottom of the cover to remove it.

5. Look for the communication terminal blocks located at the top of the VFD

6. Using a small screwdriver, press the white tabs above each terminal and insert a 680Ω resistor between the VCC and TXD +; repeat to insert a 680Ω resistor between GND and TXD-.

IMPORTANT make sure the resistors are not touching each other. You should be able to gently tug on the resistors and they should not come out of the VFD. Plug the cat5 cable back into the VFD.

8. Plug the cat5 cable back into the VFD.

9. Confirm RDX Connections: RDX+ = BROWN RDX- = WHITE with BROWN

10. Remove all foreign materials from the Stagehand

11. Plug in a motor

12. Plug in and power on the Stagehand.

13. Using the keypad on the front of the Stagehand change the parameters to match the settings.

14. After making all the changes cycle power on the VFD.

15. Open Spikemark 5.0 or later, and connect to the Stagehand.

16. Make sure it is on the latest firmware version

17. Scroll down to the drive section.

18. Next to Drive Model you should see either A800 Series or FR-A8 followed by other letters and numbers. If this is not the case jump to troubleshooting.
