Inrush current limiting

Note that in order to limit the inrush current to the MDP90A.., sizes 1 and 1A, a line choke must be used once a certain number of axis modules is reached.

Axis modules are assigned a specific number of points, depending on their size. Without a line choke, only a certain number of points may be connected to the power supply module.

The following tables show the permitted number of points for operating the size 1/1A power supply module without a line choke as well as the assigned number of points for the axis modules.
