Preamble : I don't want to write another list of what each woodworker should know in order to work safely. Everybody may find what matters using a search engine with key words "woodworking safety". Albeit all these articles talk to the others and I would have liked to find someone writing : "for my own safety I try to..." which means many more people convey a standard point of view about safety without wondering anything. I avoid these kind of topic that lead to nothing most of time. On the other hand I get involved in every exchange that tend to explain why something would be unsafe et try to find out a better way. It's all about mental attitude and the last one requires the point of view to be argued. Nothing good nothing bad but keeping open minded.WhyDi

Variable frequency drive on my woodworking combination machine...What for ? Here are the basic answers to :

• What for ? How does it work ?
• What are the benefits on the table saw ?
• and on the planer, mortiser ?
• and spindle moulder ?

But can I make it true on my combination machine ? what do I have to check at first ?

• Are the motors compatible ?
• What about soft-starting ?
• And slow down ?

How making my choice ? What is the right size ? What Is it realistic and not ?

• Sizing to horsepower ?
• Sizing to peak torque ?
• How to check Size ?

How connecting and where setting up that variable frequency drive ?

• What location, schematic diagram ?
• Maybe some variable frequency inverter diagrams ?
• Perhaps some variable frequency drive diagrams ?

What is new about handling ?
Hardly nothing if the variable frequency is connected as described in this document. I simply take care of the rotation direction glancing at the phase inverter switch and revolve the potentiometer to adjust speed as needed, between 20Hz and 60Hz.

Maybe would you like to go further ? You could see the manufacturer commercial literature of the combination machine in that document and may dowload the variable frequency drive manuals below :
