I would say that is a typo - S4 is a programmable terminal like the others unless specifically called out otherwise.

Use a setting of 17 for fault reset - I'd use S6 for wire 941 and leave it to default settings to make it simple.


For the output relays, use a setting of 1 to get drive fault output. I would wire 947 to relay output 2 (R2A, R2B) since fault output is the default setting and ensure that parameter 3-19 is set to the correct contact form.

Appreciate the help on that last one. I have 2 more I am uncertain of where to out 940 (IN COM) and 950 (AT Speed).

I have uploaded a picture with what I have thus far.

I would put 940 INPUT COM to the COM terminal between R2B and S1.

950 AT SPEED should go to the other relay output in normally closed form. That should be R1B and the common on R1C.

ok Think I have it now. Can I get a confirmation on these?
Left column is the lower terminal. Right is the top.

Code: Select all

   R2A
S(+)
    R2B
S(-)
    R1A = ORG 947 (FAULT)
SF1
    R1B = TAN 950 (AT SPEED)
SG
    R1C = YEL 946 (OUT COM)
BLANK
    BLANK
COM = RED 940 (IN COM)
    S1 = WHT 942 (SPIN FWD)
S2 = BLK 943 (SPIN REV)
    S3
S4
    S5
S6 = GRN 941 (RESET)
    24V
AGND = VIO 945 (0-10V COM)
    AI1 = BRN 944 (0-10VDC)
10V
    AI2
AO

Have some zip tie anchors arriving tomorrow so I can be done in the main cabinet here. That is as long as the control to VFD wiring is correct. Also have the 2 O-rings coming in so I can finish the X-axis stuff. Getting close to applying power.

I was going to replace the coolant pump but them I seen someone using capacitors to run 3phase pump on 1phase woring. Think I will give that a try. Can't imagine it will take too much to get this little 1/6th HP motor going.

Alright, there's some inconsistencies between your labels and what the manual from Teco-Westinghouse's website says. I don't see any S(+) or S(-) terminals on that manual so I would suggest contacting the manufacturer or doing some digging on that. I got the manual from here: https://buy.tecowestinghouse.com/Drives ... fmLg%3d%3d

Assuming that everything still matches up, you would need to put the orange 947 FAULT to R2A. You have it written as going to the same relay as the AT SPEED output which would imply that it can either be AT SPEED or in a FAULT condition.

Yellow 946 OUT COM wire should also be jumpered to R2B to complete the circuit for the orange 947 FAULT.

Everything else looks correct. After you get it up and running, you could try connecting the AO terminal to the ALLIN1DC's analog input and set VFD parameter 04-11 = 4 for current output. This would get you a load meter for the spindle on the CNC12 display.

Well don't I look like a fool. You are correct. I think that label came off another inverter. I started this project a couple years ago and it took a back burner. I had to replace the original inverter and think this label came from it.

Answers why I couldn't get things to line up the way you were telling me to do.

I am headed out now to fix things.

Ready to button up the X-axis. Got alot of wires that need terminated. The Hardinge came with AMP Series 53 connectors. Most of these were chewed up and broken when I started. Dummy me thought I will just cut them off and replace them when it comes time to put it all together. How was I to know that you need to order a minimum of 5,000 @ $2.29 each! Guess I need to figure something else out. Maybe wire some new pigtail connectors?

I am really anxious to apply power to the system. I have not done so with the VFD installed. Are there any concerns or reservations I should have before booting everything up?
When I installed the Allin1dc on my mill I had an installation manual to follow. Pretty sure this lathe was done by just attaching a ready made Allin1dc cabinet. I am concerned about which setting to use for JP1 , NPN or PNP? I recall there being somethings I had to set a certain way regarding the source sync of the dc voltage. Maybe I could use a generic lathe conversion manual?

I believe that JP1 on the VFD should be left set to NPN since you are using the COM and not the +24V terminal. From what I can gather from the manual, this would pull up the inputs to the drive's internal +24VDC supply so you would want the ALLIN1DC output relays to complete the circuit back to the COM terminal.

So, the NPN setting would make sense for use with NPN output devices and that is how the relays are likely to be wired. What schematic are you using as reference?
