One thing good to buy stuff from China is cheap. Problems with China product is their support and documentation. I came across an Inverter which is cheap... I think, manual in full Chinese characters. And it only describe the settings, but not explaining how to use it or apply it.
However, I have figure out some of the basic settings that need to get it running. Below is the list you need to set at first before run the motor for the first time.
Lets start run the motor with pressing the button on the panel. By default, the inverter will turn the motor when you press "START/RUN" button on the panel. If the motor doesn't moves, then by turing the knob on the panel to increase the power... hence motor will move.
Button on the panel is fully manual operation. If you need to use the PLC to control it run and stop, you will need to wire the input bits on the inverter.
By default, most of the inverter setting
DI1 = FWD
DI2 = REV
DI3 = Multisettings bit 1
DI4 = Multisettings bit 2
These DIn function can be configure to take other function. Check the manual, it should have lists of option to choose from.
2ndly, we are interested in Accel and Deceleration. Inverter use "seconds" from 0 to desire speed.
Check your manual, it should have an option to set the Accel and Deceleration.
3rdly, How we want the inverter to accept run/stop command. There are a few options: Panel button; IOs; or Communication port (normally RS485).
4th, How you want the motor to stops. It has 2 options: Free the motor, or reduce to stop by inverter.
Once the settings are set, motor will run the same behavior when turn on DI1 or DI2.
If you need different speed settings, then you have to utilize DI3 and DI4.
Check the manual for multisettings combination bit settings. Example here is DI3 and DI4. Because the inverter i am using only has 4 DI. First 1 and 2 has been used for direction, so left only 2 bits DI. With this 2 bits DI, you can configure 4 different settings with the combination binary method.
Above few settings should be sufficient for normal forward reverse operations. In fact, it has more capable than this. I leave you some room to explore it yourself, or you could share your adventure with me in my comment box.
