Questions & Answers
This model uses standard 115 volt single phase household power to produce 230 volt 3-phase power. power in three phases motors with three phases Variable-speed drives, in general, are ineffective for single-speed applications. motors with three phases Single- To simulate a rotating field for starting, phase motors typically use a starting capacitor and centrifugal switch. The centrifugal switch will try to reactivate the capacitor if the single phase motor is slowed down.
The L510- 101- The output current of the U variable frequency drive is rated at 4 amps. A 3-amp circuit requires 3 amps. 220Vac three-phase motor As long as you have three of them, you're good. For the 208-volt system, the phase motor's current rating is 4 amps or less. The drive will be able to provide the proper current to the motor to maintain the motor's rated torque and power in the 230Vac voltage range. This mission will necessitate a 100-mile drive. To achieve the 4., use a single 120Vac circuit rated for at least 19 amps. 3 amps of 3-phase power For the motor, there is a phase current.
Although the drive lacks a built-in FWD/REV tactile push button, an external drum switch can be connected to the VFD programmable terminal strip on board and the drive programmed to accept the external signal control.
This (or most) VFDs should not be used in this manner. They don't produce the clean sinusoidal waveform that a computer or instrument would expect. Furthermore, as part of its output circuit, the VFD's output is dependent on the motor's inductance.

This thing is incredible; I won't go into all the details that make it so versatile and awesome because no one has that kind of time; just know that this thing is no joke; if the safety guidelines and procedures aren't followed, it can kill you; seriously consider hiring a professional to assist in the installation and learning of its operations. Apart from that, this thing is incredible! It enables you to accomplish far more than the description suggests. It unlocks a world of limitless possibilities, with the user's imagination serving as the only limit. More importantly, it allows the operator to think freely. That's a one-of-a-kind combination.
My lathe's motor is controlled by mine, and it's fantastic. It's simple to set up and use, and it's very effective. I put it in an enclosure with a filtered 80mm fan for ventilation, and it hasn't gotten hot enough to touch. All of my remote controls function properly and were simple to set up. br>I intend to purchase a few more for use in my shop's other machines.
This is being used to power a disc sander with a 1 hp 3ph 1725 rpm motor. It works perfectly except when I put a lot of strain on the motor. It gives current overload, but that's probably what it's supposed to do. It's not something I'm used to having to do. When I overload a motor for two seconds, it boots. This vfd does an excellent job, has excellent documentation, is of high quality, and the fan only operates when the motor is turned on.
instructions are excellent My 1 horsepower phase 3 baldor motor now runs like butter. I'll most likely purchase another.
It's difficult to use the machine constants. Without an external switch, switching from forward to reverse is a pain.
This is a nice unit that has a lot of the same features as the $8000 ABBs I used to work with, but in a smaller package. I've only had it for two weeks, but I'm impressed so far with the fit and finish. If you're not familiar with frequency drives, there are videos on YouTube that can help you set it up.
After I figured out how to program the parameters, the product worked perfectly. It's a little difficult to understand the manual. I couldn't find any mention of holding down the enter key to adjust the selected parameter. It was simple once I realized this.
