N ote: EB models do not have rotary switches.
The CDHD has t wo 10-position rotary switches, accessible from the front of the
unit . The switches are used to set the drive address. When there is m ore t han
one drive on a daisy-chain or CANbus network, each drive must have a unique
address to enable its identification on the network.
Use the two rotary switches t o set the drive address for both CAN and serial
com munication.
For Et hernet-based motion buses, the switch has no functional use for either the
drive or the network. It can be used at the application level to identify specific
drives on a network.
Each switch has 10 positions:
The upper switch positions are set as tens: 10, 20, 30 … 90
The lower switch positions are set as ones: 0, 1, 2 … 9
N ot es: I f two or m ore drives are connected to the network, address 0 cannot
be used. Only a singular drive may have the address 0.
Two drives in the same network cannot have the sam e address.
