dsnellen,
Pin 1 to Pin 4 = 0.0 No movement of the needle
Pin 2 to Pin 4 = Max ohms
Pin 3 to Pin 4 = Max ohms
Pin 4 to body = 0.0 No movement of the needle
I am in the ohms mode using RX10 setting for all test
If you really are in the Ohms mode you should move the meter to Ohms and use the lowest range. A zero means it sees no resistance between two pins, like they are shorted out to each other. When you show MAX ohms that is an open, meaning it is not seeing any resistance or like there is no connection at all. You said the motor spins for a short period of time if you really had open connections the motor could not spin. Please use a different meter or have someone check who is familiar with a multi meter. The cable that goes to the actual Spindle should be a shielded cable, also as Mactec54 shared the spindle itself should be grounded, it is very important you don't feed the output of the VFD to the wrong pin on the spindle or you could get shocked. If you get a new spindle or even with the one you have check each pin in the spindle plug and measure it using a GOOD ohm meter to the spindle case, only one of the pins should be connected to the spindle case that is the ground pin. Some of these Chinese spindles come with only a three pin connector, mine came that way. In those cases you still need to ground the spindle case using the mounting bracket or other method, this is an important safety concern. The preferred spindle cable contains a copper braided shield, these help shield all the EMI noise that comes from the AC pulses in that cable. Also double checking all those VFD settings before you start is very important as Mactec54 shared if you set those wrong you can destroy the VFD or Spindle. Triple check everything before you connect the spindle and in your case you show the incoming AC power with the White wire stripped and hanging next to those power connections, another big NO NO. If the wire is not used cut the end off so it can't get moved and touch something and destroy the units. You should be using 14AWG wire minimum as the incoming 220V AC power, and for the three phase output should be a shielded 16AWG minimum. A good source of cables to use for Spindles is often a Servo Power cable, which can be found on ebay.

You can then just cut off the connectors and then connect them to the VFD and Spindle. This photo shows you an example, you can see the braided shield. Many people fail to get a shielded cable and then have all kinds of issues with the CNC controller due to all the noise generated. Hope this helps. Good Luck.
