Thread: IMO JAGUAR VFD help needed
I encounter a little problem operating my Denford Orac lathe with the IMO JAGUAR VC150 VFD.
I wanted to use the IMO VC150 in place of the Parajust because the last one lacks the capability for reversing.
The case here is, that the Parajust uses a 5k frequency control pot and the IMO VC150 uses a 10k pot. This means the Orac controller when applying the highest impendance for bringing the motor to a full stop. This will not happen and the motor is going to continue running at aprox. 300RPM because 5k is not enough for the IMO to completely cut the power to the spindle motor.
Also, the IMO was not fitted with a latching relay for start/stop control and the normally open momentary switch is not suitable for the IMO as is with the Parajust to activate this control.
If someone of you gents is familiar with the IMO JAGUAR VFD and successfully has made a similar modification using this inverter his advise on how one may overcome this different control impendance problem is highly appreciated.
Would it not have been easier to keep the original drive but reverse the motor by using relays or contactors to swap the motor phases?
As for the new drive, you should be able to set its parameters to take a 0-5V or 0-10V input signal from the pot (assuming that the 5K pot outputs 0-5V?). For the latching circuit, there should be a way to set that on the drive but you might need a linking wire somewhere in the start/stop/run terminals. Otherwise, you'll have to latch a relay instead.

Hi and thanks for the response.
Well, the original VFD I accidentally damaged. Its power module...a Gentron Powertherm B412F needs replacement but I have not managed to locate one yet.
On the other hand, in order to set parameters for the IMO I need the user manual for VC150 and this is something really rare to find today.
That's why i asked for help.
Parajust pot outputs 0-10 volts thats the only thing i know.

0-10V is the standard signal, so that's good news. Bad news is that you're gonna need a manual for that drive in order to set it up properly. You'll probably find that the manual for ANY if the IMO Jaguar range will be OK as they standardise on parameter numbers and functions and the start/stop/run/speed/etc terminal connections will be the same.
Maybe one of these? Power Drive Services - Electric Motor Specialists - Fuji Manuals
has a diagram on here.

This should be the same even though a different name on the unit

Damn it, I've somehow ended up on eBay looking at Jaguar XKR's and XF's. I hate this forum. :)
