Carrier 30XA - Condenser VLT's - Program Question

[ChillerR123]

Hi all, can someone advise if the Carrier VLT's (Danfoss HVAC Drive in disguise) are able to be programmed in the field (Carrier firmware upload), or ONLY from Carrier at factory level.

I mean, a Danfoss HVAC drive is like $2k, yet an equivalent Carrier is like $6k.

Thanking you.

Is there something special with the VFD?

Have you tried using danfoss software to pull the program out?

I've not done it on a carrier but on the latest Daikin screw I've seen that the were using a standard drive.
I don't believe carrier have asked for a OEM.
The only limit you have is if there is a password.
But if it's the vfd with the 4 button under the screen just hold all 4 buttons to bypass the password
