3.1 Overview 
 
The Control and Display Panel [Control Panel] is used for parame-
ter setting, for feedback value measuring and for drive control with 
series DCS 500B / DCF 500B and DCP 500B thyristor power con-
verters. This device is available in different versions depending on 
the type of unit and software to be used: 
Units with software S 21.1xx 
  CDP 310 or CDP 311 
 
 
(recommended: CDP 311
Units with software S 21.2xx 
 CDP 
312 
Hereinafter CDP 31x will be used as a common type designation for 
the above mentioned versions of Control Panel. Differences be-
tween the versions which have to be taken into account with par-
ticular functions will be indicated separately! 
 
Panel Link 
 
 
 
The CDP 310/311 Control Panel is connected to the drive via 
CDI-300 communication bus.This communication bus, which is 
based on the RS485 standard, is a common bus protocol for ABB 
Drives products.  
MODBUS is used as communication bus connecting the CDP 312 
Control Panel to the drive. This Control Panel combined with a 
Software version S 21.2xx onwards makes it possible to show the 
texts on the LCD in different languages. 
The selection of language is performed by parameter

Mounting the  
Panel 
The CDP 31x  Control Panel can be handled in three different ways:
• 
Direct mounting on the thyristor power converter; the CDP 31x is 
plugged into the moulded part of the cover of the converter and 
connected via an adaptor of approx. 45 mm. 
• 
Mounting on the door of the switchgear cabinet using an assem-
bly kit equipped with a connection cable. 
•
