Re: Milltronics Partner I
What does CSP 3 speed spindle drive mean? I have a milltronics partner 1d that has 3 pulleys for speeds. low, med, high. Can this machine run on single phase 220v?
Re: Milltronics Partner I
Hi Rivethead, CSP is a typo, It should have been CSM ( Custom Servo Motors) This is an electronically shifted 3 speed motor. with a max 4500 RPM.
On your machine you have to swap the belt for the different speed ranges and set the spindle range parameter, (1 =low, 2= med 3= high)
Your P1D can be run on single phase. Wire your 220vac (10 GA multi strand wire with a 30 A breaker.) to L1 and L3 and jumper either L1 or L3 to L2. don't forget the ground wire.
Check the incoming voltage, 220, 230 240 or ?? and check the 220 to 110 transformer, below the disconnect switch and match the incoming voltage to the closest tap on the transformer.

Hi Rivithead, It might be OK where it is ( 260V) Check the 110VAC at terminal blocks 1 and 2. it should be 110 to 120V. If it is under the 110V, then move the transformer wire to the 240V tap and recheck.
I suspect that the green wire in the pic is the incoming ground wire. Connect it to the upper ground stud above and to the right of the disconnect switch.
wire your single phase to L! and L3 of the disconnect switch and jumper either L1 of L3 to L2. ( this "L2" jumper will go on down to the spindle drive.

Re: Milltronics Partner I
Do you still have this machine if you do can you please send me a picture of the main reset contactor CR1 relay, Got a machine with out it got the relay but I found some jumper wire in the cabinet and I'm sure that is part of the relay the schematic won't you it. It show how is wire but there are more wire going to the relay that are not reflected on the schematic. Thanks
