Npaq® Hardware Manual
Installation and Configuration
2.3. Communication Channel Settings
Use the Device Number switches of S2 to assign a communication channel number to the Npaq. If you are
using multiple drives, each drive must be assigned a unique communication channel. Multiple drives are
typically configured using sequential communication channels.
Figure 2-4:
Device Number (S2) Location
N O T E :
The drive assigned to the first communication channel number (all switches set to ON) will be
configured by the Axis 1 parameters defined in the software. The drive assigned to the second com-
munication channel will be configured by the Axis 2 parameters, etc.
The Npaq drive chassis can be set to any communication channel number from 1 to 27 (the Npaq will
automatically claim the next 5 sequential device numbers). If the Npaq is set to 2, the next available
communication channel number is 8.
