Other/General Applications / Re: conveyor motor control by VFD

If the following two conditions, then Invt GoodDrive100-PV is pplicable, because they mention in the manual that their inverter can supply a single phase motor.

1- Solar Application
2- Load is a pump

You can check the inverter manual, the attached picture is from the manual.

I am wondering what could be reasons for braking resistors overheating!!

We made correct selection of brake resistors as shown in the inverters manual, even though, the brake resistors keep heating.

Can someone help in this? They are installed on a hoist motor of an overhead crane.

Hi everyone
I would like to check if any one tested the following inverter in Saudi Arabia or any GCC country, we are providing solar solutions, and looking to expand to GCC countries.

The proposed model is:
- Invt Goodrive100-PV

does any of you have an idea if this fits to GCC environment? Ambient temperature and dust?

Thank you

Other/General Applications / conveyor motor control by VFD
« Last post by KgSwat on August 18, 2019, 10:33:46 PM »
Hello guys  :038: . We would like to upgrade a conveyor in our plant, we would like to add a VFD to regulate its speed and make smooth changes in speed.
 :dft008: :008: :045:
The problem is that the conveyor is 180 meter away from the control room  :016: , and I know that the maximum distance between VFD and motor is 50m  :51: .

What do you suggest?  :55:
