I have the pdf file and have tried to follow the instructions in the manual but just can't seem to get started. I understand the first step is to input all the information necessary off of the motor plate. But what I need is a "First Push this button and then push this arrow etc etc." I have tried and tried and can not seem to get to first base. Any help would be greatly appreciated. I am trying to resurrect an old 5913 Clausing lathe that has a 2 hp 3 phase motor on it. I will be using the original hydraulic Reeves drive to vary the speed and the drum switch to change directions of rotation so all I need to do is make the VFD run the motor on 3 phase @ 60 hz. The VFD comes from the factory set up for 50 hz. Thanks again.
I am writing this based on my experience with Hitachi VFD's and all together too many years being paid to write computer software. Feel free to ignore everything you see here.
I think the first thing to do is dump the drum switch for the direction change, especially if it has a no-direction position between forward and reverse. Two reasons ...
First is that the VFD can do it much better than the drum switch.
Second is that, if I understand how it is set up correctly, your intention would be for the VFD to feed the drum switch and then the drum switch would feed the motor. That means that when you switch directions the connections from the VFD to the motor will be interrupted. The drum switch needs to break the connections to at least one pair of windings, switch them around and then reconnect them. Some VFD's may be tolerant of the motor being disconnected when the VFD is on and others may become upset and let the magic smoke out. It has to do with how the VFD components synthesize the three phase power from a single phase input.
Worse yet is if the VFD is powered up and the drum switch is in the neutral position. Again, it is related to the VFD technology that really does like having motor windings connected to the output.
Now, assuming you have dumped the drum switch, which buttons to push ...
We'll assume that you've followed the instructions as best you can related to Chapter 3, Installation of Frequency Converter. I know section 3.3 suggest lots of parts in the power path but I have several VFD's and only have (a) a circuit breaker [no local to the VFD but the VFD is on a dedicated circuit so the breaker is in the box]; (b) the VFD; © the motor. No AC Contactor, no input AC reactor, no Input AC Noise Filter or DC reactor, no AC noise filters, they all have Braking Resistors on them but that is not necessary to get the boat to float the first time, no Output AC Reactor. In the future ... more CNC tooling, etc. ... I may need to put some of the noise filters in place but for now everything seems to work fine without it.
Moving on to Chapter 4, Operation and Display, or "what buttons to push".
The key appears to be figure 4-3, the PRG/ESC button and keeping track of what level you are at in that diagram. PRG (program) will take you to the right one level, ESC (escape) will take you to the left level, and the arrow keys (increase is the up arrow, decrease is the down arrow) will either move you around at any give level or let you change the value in the display.
Give this a try ...
You are staring with the display showing something. As an example we are going to try and set the b0-02 parameter, Motor Type Selection, from the table at the top of page 36. The first thing we need to do is get to the B0 at level-1. Press the PRG button to go to the right one level. The display should show you where you are on level-1 ... a0, b0, b1, etc. Now use the arrow keys to switch between the items on level-1 until you find the one you are looking for -- b0.
Now press Enter. This should take you into b0 and you should see where you are in level-2 ... b0-01, b0-02, etc. We are looking for b0-02 so use the arrow keys to move thru stuff available in b0 level-2 until you find b0-02. Press enter.
You now use the display should show the current value for the parameter and the arrow keys will be used to change the parameter value. But what does the parameter value mean and what should it be set at. In our example page 37 gives that information. I think we want the parameter value to be 0, keypad control. Use the arrow keys to set the parameter to 0, or do nothing if it is already zero. You can now press Enter to set the value. This should take you back to b0-02, i.e. b0 level-2.
You can now press ESC to escape from b0 level-2 back to b0 level-1 and then ESC to escape from b0 level-1 back to the the main display.
Give that a try and see if that makes sense.
If (a) it actually works and (b) you feel you have a sense on how to navigate the levels you can then move on to advance methods ... not coming all the way back to do the next parameter but rummaging around at level-1 and level-2; using the ESC escape key rather than the ENTER key if the parameter is already set to the value you want, etc.
