AMB 1400 FME Spindle

​

Caution: Before any VFD can be used it must first be configured correctly to work with your spindle.
Incorrect spindle configuration can lead to damage of the Spindle, the VFD or both.
This diagram is based on the default configuration shown in the VFD documentation.
Please be aware that changes made to configuration and link on the main board may make this drawing incorrect.

Speed Control
This spindle has a non standard 1-9v speed control signal instead of the 0-10v used by other spindles.
This will give a non linear speed when used with MASSO

Fellow forum member ZombieEngineer has devised this simple divider circuit to bring the speed control into line with MASSO speed control.
It can be made with 3 readily available electronic components. The connection diagram above does not include this circuit. Add as needed.

Masso output on the left, AMB input on the right. If the configured maximum spindle speed is 22,000 then the AMB spindle should match within 0.5%. The above circuit is effectively a voltage divider with the diode providing a voltage bias [ Y = 0.95 x (X - 0.6) ]

Updated wiring diagram incorporating the voltage divider circuit presented in the previous post and using the CW Optocoupler instead of the MASSO relay module

WARNING: This has not been tried and to date no-one has provided feedback on the previous diagram so it is unknown what does or does not work.
Proceed with caution.

If someone has connected this spindle to their MASSO please provide feedback
Cheers Peter

On request Peter, I implemented this solution with fabulous results. Just a slightly higher rpm, probably caused by my cheap measuring tool.
Peter thanks for pointing me to the solution

ZOMBIE THANKS FOR SHARING have on me

I did make a mistake. Problem is solved, rpm is within a couple of revolutions
