Where should the speed signal wires connect to the 0-10 VDC analog input in an Econoflex drive?

If modification J09 is included on the drive wire the positive to S2, negative to S3 and the shield to S1.
Without the mod J09 the 0-10 VDC input is normally used for the potentiometer. If that is the case it is recommended that you install a converter to change the 0-10 VDC signal into 4-20 mA.
Or if your system accommodates a 4-20ma or 0-20ma singal output use that instead.  Then connect the positive to S2+, negative to S3 and shield to S1.
Otherwise abandon the use of the speed pot and wire to the COM and AI1 or use a relay to switch the AI1 signal from the potentiometer to the remote 0-10 volt signal.
The part number for the signal converter is 31158-297-50
When using the above kit wire as follows:
**** Identify the DC control terminal configuration.******
               If there are eleven terminals:
   a. Remove the wire connecting AI2 to terminal block S2 from the wiring
harness.
   b. Connect the control wiring removed in Step 1 to the 0-10 Vdc
converter board terminals.
   c. Connect the 0-10 V signal wiring to the converter board terminals AI2A (+) and AI2B (-).
   d. Insert the converter board pins firmly into the control terminal plug as shown in Figure 2 of bulletin 30072-450-45, and tighten the terminal screws.

                  If there are twelve terminals:
   a. Connect the control wiring removed in Step 1 to the 0-10 Vdc
converter board terminals.
    b. Remove the factory installed jumper on the DC terminal blocks fromS2+ and S2-.
    c. Add a wire (14 AWG, 1.5 mm2 max.) to the harness from S2- on the terminal block to AI2B on the converter board.
    d. Insert the converter board pins firmly into the control terminal plug as shown in Figure 2 of bulletin 30072-450-45, and tighten the terminal screws.
     e. Connect the 0-10 V signal wiring to S2+ (+) and S2- (-) on the
terminal block with a max. wire size of 10 AWG (5.26 mm2). The
tightening torque is 7-8 lb-in (0.8-0.9 N-m).
