Introduction

Description
Control Units CU320-2 PN and CU320-2 DP of the SINAMICS S system are designed for use with
several drives.
The number of variable-speed drives depends on:
• The required performance
• The required additional functions
• The desired method of open/closed loop control (servo, vector or U/f)
The software and the parameters are stored on a plug-in memory card.
The option slot is used to expand the number of terminals or adapt to other communication
interfaces (to the higher-level control).
Compatible firmware versions:
• CU320-2 PN V4.4 or higher
• CU320-2 DP V4.3 or higher
