Hi, I have not used that input and cannot seem to find any information on whether this unit will do what you require. sorry to not be more help

[@wesleyooms]

@@andrewwatts5625 Ok no problem. Thanks for the reply. I'm starting to doubt if it's possible what I want with this VFD so I decided to buy another one that specifically states it has rs485 communication; the SUSDE 310 series. Unfortunately I now have a VFD that i probably cannot use. Before buying the A2-8022 I couldn't find this functionality anywhere so I asked ChatGPT (Artificial intelligence) and it responded it's possible. Moral of the story; don't always blindly believe what AI says.

[@jeffpeters6561]

Thank you for the video, I have that VFD and I put it on a Delta wood lathe and added a 3 phase motor. I was having trouble programming it, question does the display flash the whole time and what is the speed control parameters? Thanks

[@andrewwatts5625]

Hi all the time the controller has power but is at rest it will flash either the max speed or max frequency according to which you have selected to display. once you hit run it will show the ramp up information and finally the run Fequency/Speed. The max frequency(speed) is set with Pn10, Minimum Pn11, accelerartion Pn08 and Deacceleration Pn09 also set you motors rated fequency with Pn12 (60, 50 or 400hz?)

there is a few way you can do that, 1 would be using an op-amp, another would be using an "Arduino Uno" Circuit which you could power from a standard USB power supply. both methods have a lot of information on the web so you can get full instructions on how to do it. another would be to use a signal converter from Sensorsone but I do not know how much they are www.sensorsone.com/isocon-3-port-isolating-signal-converter/ Hope this helps

Hi Bob. I had the same issue, and finally found that P32 is the issue. To drive a 3-phase motor, you first need to set P32 to '50Hz' mode (6), and then adjust parameters from there. I suspect there are other (hidden) parameters that the P32 sets up to control voltage, current etc. It seems to come preset to the 400Hz mode (eg CNC spindles), which is why I didn't have a problem last time I bought one of these (for my CNC).

hello, how did you set the torque to maximum at all speeds? i did not get to and when i go low speed torque is weak thanks in advance

[@andrewwatts5625]

Hi Pn 13 controls the torque compensation (Default 0.0 max 4.0), Pn 14 sets the torque compensation frequency (Default 80hz). With constant torque applications, there is a possibility that the motor will overheat during low speed operation, also less cooling air flowing through it does not help. A constant torque load draws the same amount of current regardless of the motor's operating speed. This creates a problem at very low speeds, because the VFD reduces motor frequency in order to decrease motor speed. If the motor produces a high level of heat while operating at low speed, overheating results. As a rule of thumb, a fully loaded motor with Class B insulation running at 50% rated speed on a constant torque load will not overheat. If the motor is run below 50% speed continuously, it will overheat. so try increasing the Compensation figure but watch for overheating. if I am requiring to run at slow spindle speeds where high torque is required for an extended time I alter my drive ratio (either set to low range or alter the belts drive) so the motor is running faster. hope this helps
