Connector Pin Assignment
Note
The signals ERR0 and ERR1 transmit the status of the power supply unit to the connect-
ed drive amplifiers. These signals are generated by each power supply individually and
must not be connected between two power supply units. This also applies to the power
supply units of compact devices.
If several devices are connected in a system, the 24 V logic supply must be supplied to
one device from an external source. Then the logic supply is forwarded from that device
to the next and so on via X1 and X2 (see chapter 14 “System Connection”, page 154).
