I want to connect the DC-bus of two axes. Of course, this is not a problem. The obvious choice would be to use an XCS as the supply and an XMS as the second drive connected to the DC bus.
However, to keep the bill of materials small, I am now opting for two XCS*-W0010 Amp drives. One XCS will be connected to the mains, and the second XCS will receive its supply via the DC bus of the first XCS. So in total two XCS drives.
Now it comes down to the parameter settings. I can't really set in the drive firmware that I'm only using the second Drive as an inverter. I assume that the drive will simply go into 'ready' (bb/Ab) mode once the DC bus has reached the desired voltage level.
I see no showstopper and will proceed with this. However, a checkbox in the drive would have been desirable. As far as I know, this was provided for in the IndraDrive.
Since we're on the forum, a question:
Can I connect the DC-bus of XCS to XCS, provided the power requirements are sufficient?
As before in Indradrive :
Addition / Update : Be aware that there is a significant difference between the various drives. Depending on the selected type, specific connection combinations may be possible. With the standard modular XCS-A series, the DC bus must not be coupled if all XCS drives are connected to a 400V mains supply. However, with the compact XCS-H variant, this is indeed possible, you may connect the DC-bus and supply all the drive with the mains. So it depends on the specific drive chosen and its detailed technical specifications. It can be done—but proceed with extreme care!
