5  Communication and user modules
5.1 Principle of 
function
Communication and user modules expand the functionality of the
CDA3000 drive system. On the base module there are two slots, into
each of which one expansion module can be plugged.
Characteristics:
• Usability of the modules on all inverter
sizes
• Simple retrofitting of expansion module by the user
• On inverter modules up to 15kW side mounting, on modules above 
22kW on the front of the device
• With side mounting the base unit is 25 mm wider
Communication module
e.g.  CANLust
        CANopen
        PROFIBUS-DP
Control terminal expansion
e.g. eight additional inputs and four addi-
tional outputs
