Ladder Diagram for KF700S

 

Does anyone have a ladder diagram for the motor control for the KF700 S?? I have the schematic that came with the saw, which is helpful, but also somewhat confusing.? A ladder diagram would be so much easier.
?
I've found that my off-grid power system really does not like the electronic braking system.? It's also not entirely happy with the inrush current.? I'm looking to integrate a soft start like I have have in my other large tools and disable the brake board.? Disabling the brake board is pretty easy.? The schematic shows what needs to be jumpered if there isn't a brake board.
?
I want to change the sequence so that the start button initiates the soft-start, and have the soft start disconnect the starting caps when it's finished with the ramp sequence.? Similarly, I need the stop button to open the control circuit for the soft-start.
?
(Note:? I'm aware that electronic brake is a safety feature.? This is for personal use and I'm willing to live with that risk to not cause damage to my inverters)

Hi Michael,

I have heard of these current limiting devices but have no personal experience. It may be a simpler solution.


We never learned ladder logic in ELectrical Engineering, so can’t help you there but if you share the machine wiring diagram. I can annotate it with how the machine powers up and powers down.
