8.6.2.2 Wiring example 24 VDC supply
Maximum current for one string of daisy-chained X10T connectors is 20 A. The sum control
current of connected drives should not extend 20 A. With the data given in the table above,
you can connect for example:
6 single axis drives, or 4 dual axis drives, or 3 2 dual axis drives.
