We try to help with problems if we can but we can't do it all for you. As was mentioned previously we aren't trying to be mean but we can't hold your hand every step of the way. You need to learn how to do this on your own NOW because you will need to be able to make changes as needed later on too. Every parameter is described in your owners manual. You can only change the voltage by connecting the coils in series for the higher voltage and in parallel for the lower voltage.įor a nine lead motor the internal connections of 10, 11 and 12 determine if the motor is wye or delta.(01-24-2018, 02:18 PM)Highpower Wrote: (01-24-2018, 11:54 AM)sun20ma Wrote: can anyone tell me the parameters I AM LOST WITH THE SOFTWARE Grizzly lathe G0602 with a Automation Direct GS2-11PO only using it's keypad with a Leeson 192051 1800rpm 3 ph 230v We have a dual voltage motor with a nominal 75 Hp rating at 60 Hz. In my lab we use this exact setup on a piece of test equipment. So a 480V VFD can be set to a VHz ratio to properly operate a 230V motor.īut remember that a VFD has limited output current, and if you reconnect the motor for lower voltage, the motor will require higher current to operate. So you would use a 230460 dual voltage motor, wired in the 230V configuration but connected to a 480V VFD.īy its nature, a VFD must be able to produce a lower voltage than its input. One possible reason is if you want to operate a motor at greater than rated base speed.Ĭommon NEMA induction motors rated for 60Hz base speed are often rated for operation at higher frequency contact the manufacturer for details. Other than saying call the drive manufacturer for your application, theres no information conveyed in your post. The European motor connected 460 Y, if you reconnect it for 230, it will probably be Y again. If the drive is adjustable for the lower voltage, it is not going to be rated for double the current at the output. That may not be programmably adjustable (refer to the drive manufacturer).Ĭheck with the drive manufacturer if your drive matches what you want to do with it, regarding the system supply and load side voltages, and if so any kW derating that may apply.
It would go back to the factory ratings of the drive and what you are trying to do with it. Is the motor already running or is it a new installation The motor may be dual voltage but the drive may not be.
