Programing the VFD on a Jet 1642 Lathe

You can download the manual with programming instructions. Search for Delta Electronics VFD-S manual. If reprogramming one sold by Jet or Powermatic you may have to find the unlock code online to change parameters. One guy said Jet finally gave him the code since his lathe was so old.

Mine 1642s are the 115 volt models but I suspect the parameters are the same.

These are the parameters I copied from one of my lathes:

------------------------------------------------------------------------------

Jet 1642 VFD parameters Delta VFD-S series, 115 volt version

(I made a note in my manual that this is VFD0075S11A style as shown on pg c-12)

These three parameters are read-only, perhaps are hardwired

0-00 4 (identity code, read only)

0-01 4.2 (capacity in amps, read only)

0-06 2.3 (read only)

These are the parameters different from the defaults

All other parameters are set to factory defaults according to the Delta manual

1-00 132 Max output frequency

1-01 60.0 Max voltage frequency

1-03 5.0 Mid-point frequency

1-04 20.0 Mid-point voltage

1-05 5.0 Min output frequency

1-06 20.0 Min output voltage

1-09 5.0 Acceleration time

1-10 5.00 Deceleration time

2-00 1 Master freq determined by analog signal 0v-10v

Position of jumper J1: top two pins for voltage signal input

2-01 2 Operation, keyboard stop disabled

4-09 1 Enable line start lockout

6-00 0 Disable over-voltage stall prevention

6-01 390 for 230v series (should be factory setting)

6-08 1 Present fault record: over-currrent

6-09 1 Second most recent fault: over-current

6-10 1 Third most recent fault: over-current

7-00 120 Motor rated current

The unlock code for the S-1 is 506

Many thanks to John and Dwight for their information on how to program the Delta VFD on a Jet 1642. With their information and by consulting with others, I was able to get my friends 1642 running like a top with the additional modification of being able to get the minimum speed down to 25 rpm instead of the "factory" set minimum of 50 rpm. This is very useful for finishing on the lathe.

Thanks again, Peter

Excellent! The first thing I did when I got the first 1642 years ago was go through the parameters one at a time and write down those different from the defaults. It's great to know they are once again useful to someone!

Sorry to reply to such an old message, but I wanted to thank you guys for providing this information. My own Jet lathe is now up and running after a replacement of the Delta VFD and some other repairs.
