I have a Hitachi WJ-200 series inverter that I run three different tools off of in my shop. I have it set up on a 10/3 4 wire rubber cord. When I run a particular machine, I just switch the cord. I power a Clausing 13 inch lathe, a Boyer Schultz surface grinder, and a Kalamazoo hack saw off it. I believe the unit is rated for 3hp max load. 240 V single phase input, 3 phase output. I recently purchased a Cincinnati Bickford Super service drill press and when I try to power it, I keep getting an error code on the VFD. I wired is just like I did all of the other machines, and had no issues with the ones I'm running except for switching two wires to reverse the direction of the surface grinder. The spindle and pump that works the table feed was turning the wrong direction. After I switched the wires, it ran fine. I tried switching 2 wires on the drill press, but still get the same code. The code is E013. The press is 240 Volts, 3 phase. It has a magnetic switch that reverses the motor for tapping operations if you desire to use it for that. IN the control box, there are three feed wires and one ground. The ground wire attaches right to a lug in the switch box. Anyone have an idea what my problem is? The only thing that I can think of is that maybe the coils that actuate the reversing switch run on single phase and the switch is not wired correctly, hence the error code. I'm no electrician, but I do know my way around machine wiring a little bit. This has me stumped. The VFD runs all the other tools fine. I'm going to look at the wiring schematic on it at Keith Ruckers vintage machinery website to see if anything look incorrect. I am attaching a link to the manual in pdf for these drill presses. On the last page there is a simple wiring diagram. Any help or suggestions would be appreciated.
