A CU310-2 Control Unit can perform the communication, open-loop and closed-loop control functions for one Power Module. The performance extension is not required in this case.

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:

• Safety Integrated Extended Functions, order code F01
• High output frequency, order code J01
• DCB Extension, order code U01

The firmware options can also be enabled subsequently. You will need the serial number of the CompactFlash card and the Article No. of the firmware option to be enabled. With this information, you can purchase the associated license code from a license database and enable the firmware option. The license code is only valid for the CompactFlash card declared and cannot be transferred to other CompactFlash cards.

Subsequent licensing is possible in the Internet via the WEB License Manager by generating a license key:
