Converter settings - АС Привод

3.1. I bought a frequency converter with a single-phase ~220V power supply, connected 3 wires from the engine to it. It spins on an unmarried course, stops under load and gives an error. Power does not develop. What is the reason?

Most likely, you have a 380-volt motor and it is switched on by a star. For normal operation from a ~220V household network, it is necessary to switch the motor windings to a triangle. To do this, open the cover of the terminal box on the engine and rearrange 3 jumpers there. How to rearrange is usually drawn on the back of the cover (there is also this picture in the instructions for the frequency converter).

3.2. We have your converter, I went to its menu for configuration, and there are no such items as in your instructions on the website. What should I do?

When turned on, the frequency counter gives the software version number. Download the instructions for this version, everything will match.

3.3. I bought a frequency converter, connected a 1.1 kW motor, set the frequency to 1 Hz. The shaft rotates, but I can easily stop it with my hand! Why does the engine pull so weakly?

And you first set the compensation in point 4-17 at least 60% and try again. Better yet, turn on the automatic torque compensation mode and configure it according to the instructions. It is unlikely that you will be able to keep him. For heavy loads (reciprocating compressors, extruders, forklifts) you can simply turn on U/f curve number 3 in item 4-01 if you cannot set up automatic compensation. By default, the compensation is small to avoid excessive heating of the engines at low speeds. If you force traction in the above ways, do not forget to monitor the temperature of the engine and do not allow too long work at low speeds under heavy load.
