CDPI-01 communication adapter module   17

Bus termination and chaining examples

Bus termination is required to prevent signal reflections from the 

bus cable ends.

Example: Chaining a control panel

This figure shows how to chain a control panel to several drives.

Drive 1

CDPI-01

X101

…

X102

S100 = OFF

S101 = OFF

Drive 2

CDPI-01

X101 X102

S100 = OFF

S101 = OFF

Drive n (max. 32)

CDPI-01

X101 X102

S100 = ON

S101 = OFF

1) 

The control panel terminates the bus at its end, so only the other end 

of the bus must be terminated.
