Most VSDs have a control panel. Those VSDs start to differentiate themselves from each other based on the readability of the display and how easy it is to navigate around within the VSD settings.
ABB drives allow equipment designers to go one step further, and use a single control panel wired into multiple VSDs.
A great application example is an HVACR Fan Array application with 1 drive per 1 motor/fan. Let’s say it is a little 2x2 array. In many package designs, control panels are brought to the door. If a drive like the ACH580 is used, now only a single control panel needs to be brought to the package’s door.
This flexibility gives designers the option for a more cost-optimized design, as the cost is saved on the control panels, mounting kits, and the labor to install on the door. Cost savings that can be passed on to the owner.
Also, this feature does not rely on a single drive’s power supply to power the control panel. So, if a single drive were to fail, the control panel would stay powered and functional.
This feature is all about giving designers flexibility. Can we do 1 panel per 1 drive? Yes! Can we do 1 panel per multiple drives? Yes!
The Technical Note 061 goes into detail on how to set this up.
