I have an Altivar16 VFD connected to a 1.5Kw 2HP asynchronous motor of which it is rated to. I originally had it running but at 25Hz and I pressed stop too long and reset it which in turn stopped the motor running.

not familiar with that particular model, but...

have you checked for fuses, or any other protection device for integrity?
do you have the operating manual?
when it was initially programmed, where there any key functions programmed in?

there should be a feature where you can restore the program, or, restore to factory defaults.

Googling for "Altivar 16 user manual" turned this up as the second result:

When I first connected everything the motor ran. It was running at 25 Hz and I was unable to adjust the speed so I attempted to program it to no avail. I think I unintentionally reset it in the process of doing this. After this the vfd was live but the motor would not run. The age of the vfd was evident in the complexity in programming. I believe the original use was part of a network of vfd's connected to a central plc of which it was running a conveyor. Due to this fact it was not utilising the variable speed function and was fixed speed and had a preset speed by way of fixed Hz. Its' sole purpose was to start up a three phase motor from a single phase power supply.

I bit the bullet and purchased a simple vfd which has a start/stop fuinction and a simple dial to vary the speed.

Thanks for the replies I appreciate it.:smile:

altivar vfds are very hard to program, i set up fews per year and manual is always needed. on the opposite i used some gs3 vfd from AD and also some ABB and i dont even need the manual since they are very easy to understand with their text display

I have to agree with you the manual that is available is more of a specification sheet with little information as to how to program it. The VFD I purchased was from a company called ASA Industry. It is basic as it has no reverse function which I do not require but is basically a plug and play setup. Very Happy but disappointed the altivar is going to waste.
