Acs350 factory reset

I have come across a couple of 4kv ACS350 drives which I will be using with some 3 hp motors but I cannot work out how to factory reset these drives. I have read through the whole manual and no mention of how to reset them.

Thank you in advance

Hi,
Just set in 9902= ABB STANDARD (1)
Restart the drive by power off. Then you can modify the parameters, At the end you can save the configuration in user S1...S3
Check also if 1605 = NOT SEL

Thank you. I guess there is no way to reset everything to factory defaults.

I have not had my experience with these drives and I know they are fairly old now but is it normal for the fan to be working are full spread all the time? Or has this been set this way?

Actually, 9902 restore factory settings to all the parameters. ABB Standard is the default factory macro. I think you have to proceed with the new ID run after that, and the end of commissioning, to save your settings, as it is described in the manual.
About the fan - I don't know for parameter to control it. Control mode should be defined internally, I don't know how. May be it will stop with some delay after run command is removed? Still, ABB mentioned the estimated life of the fans is 25000 h. ACS350 is designed as a small machinery drive
For other drives I know it is possible to adjust fan control, but normally when the drive is running, the fans are also running

Factory default parameters are also written in parameter list in the manual. I don't believe you have to change so much of them from the factory set

Thank you for your assistance. I have the drive working fine now and I am beginning to familiarise myself with the settings now.

Just can't still a work out the fan. As soon as I pug the drive in to the power the fan begins running at full speed. I feel it will need replacing very soon.

It is not sure - most probably not. That are small fans, line in the PC's processors for example. look in the manual for symptoms if you need to replace the fans

there is integrated counter for working hours of the fans - look in the parameters 2902 / 2901

I am going to replace the fan regardless l.
I am just wondering if it is normal operation for the fan to be operating at full speed as soon as power has been switched on and the fan run constantly at full speed. Other brand VFD I have use are more silent and fans just turn on when required

You have to ask the producer for that. I think if that is a machinery drive, the target was to have a competitive price with a simple technical solution. ACS350 is a quite old model, AFAIK not in regular sales anymore. I don't know how is it with the newest models.
