A CU310-2 Control Unit can perform the communication, open-loop and closed-loop control functions for one Power Module. The performance expansion 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 (currently the Safety Integrated Extended Functions). To order the Safety Integrated Extended Functions (Safe Stop 2, Safe Operating Stop, Safely-Limited Speed, Safe Speed Monitor), order codes (F01) must be stated in addition to the Article No. for each axis.

The firmware options can also be enabled later, for example, if, at the time the order is placed, the intention is to enable Safety Integrated Extended Functions at a later time. 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:
