15-09-2020 #22I do think that VFD parameter setting is the way forward on this. But, just thinking about the wording above - I understand about 1 to V 2 to W and 3 to U - that's fine. Provided that the wires 1-3 on the motor are connected to the windings. 95% convinced that they will be, but work checking. You said "using my tester on the connectivity setting I tested each wire" - I don't quite understand your meaning. If I was testing which 3 of the 4 wires then I'd use a multimeter on the resistance range, and measure between wires 1-2, 2-3 and 3-1. These should all read about the same - somewhere around 1-3 ohms (I'm throwing a bit in for meter leads etc). And 1-4, 2-4, 3-4 should be open-circuit (possibly a high value if 4 is connected to the spindle metal enclosure - especially if held in your hand whilst measuring. If I squint hard enough at your words I could guess that's what you mean, but it's worth checking. VFDs don't particularly like having no load connected, and hate having a load disconnected when running, so worth to double check your understanding of your wiring before you power-up again.Hi Doddy
Just seen this ,,,bugger .never mind onwards and upwards.
Here is a few photos of the VFD that i purchased today , I bought this one as i didn't want to go and spend a load of money on a real good one yet as i would like to see if this set up works first and if it is viable .
The wire for the spindle was marked from 1 to 4 to start with so i soldered Wire 1 to pin 1 . Wire 2 to pin 2 and so on ( this was on the socket for the spindle.
And using my tester on the connectivity setting i tested each wire and connected them as follows
I connected the No 1 wire to the V
No 2 wire to the W
No 3 wire to the U
Then i pressed run and turned up the speed and at H 16 an error message came up.
any ideas please
Let us know how you get on with this, and the parameter setting. Oh, and note down the original settings for each parameter changed, if already set to non-factory setting in the manual.
