CU320‑2 PN Control Unit

The communication, open-loop and closed-loop control functions for one or more Motor Modules and the Line Module are executed in a CU320‑2 Control Unit. The CU320‑2 Control Unit is essentially designed for multi-axis operation.

CompactFlash card for CU320‑2 Control Units

The CompactFlash card contains the firmware and parameter settings. The CompactFlash card is plugged into the appropriate slot on the CU320‑2 Control Unit.

A CU320‑2 Control Unit can perform the communication, open-loop and closed-loop control functions for several Motor Modules. The computing capacity required increases in proportion to the number of connected Motor Modules and system components and in relation to the dynamic response required. For the CU320‑2 Control Unit, the performance expansion is necessary for machines with 4 axes or more. The utilization of the CU320‑2 Control Unit can be calculated with the SIZER for Siemens Drives engineering tool.

In addition to the firmware, the CompactFlash Card also contains licensing codes which are required to enable firmware options.

In addition to the Article No., the following firmware options can currently be ordered with or without performance expansion:

• Safety Integrated Extended Functions, order codes per axis F01 to F06 (see section Safety Integrated)
• High output frequency ¹⁾, order code J01
• DCB Extension, order code U01(further information about DCB Extension and license upgrades can be found under Drive Control Chart (DCC) in the section Engineering tools)

After the appropriate license has been purchased via the WEB License Manager available on the Internet, firmware options can also be subsequently enabled.
