It looks like it does. But be aware that may require an option card. It does in those I use. They have the connections and protocol, but need the option card to be installed as they do not have the RS485 interface as standard. Regards Einar On 22 Feb 2017 at 11:24, dragon wrote: > Here is a

Re: [Emc-users] VFD recommendations

AFAIK any quality VFD made in the last 5+ yrs will be sensorless vector drive, at basically the same cost as earlier VFDs. Hitachi WJ200 is a sensorless vector drive. It's not super-expensive, and it's a Hitachi. Yes it has a Modbus driver for it. HY has worked ok for people, but I would

So it looks like perhaps only the 7.5kW model is the new GT series. I don't need anything near that big so if I go with the Huanyang I would be getting the model that uses the existing driver. Looking at the driver docs and code, it looks like there is no way to request the motor load. However

I want to start looking for VFDs for my lathe and mill conversions. I have two 2hp 3 phase motors to use for the spindles. Of course if I came across a 3hp for the lathe some day it might get upgraded. Are there any drawbacks to using MODBUS instead of the usual analog 10v interface? Does anyone
