Safety functions integrated in the drive
Extended functions include several basic func‐
tions and additional functions to safely monitor the
motor speed:
● STO and SBC basic functions
● Safe Stop 1 (SS1) with speed monitoring
● Safely Limited Speed (SLS)
● Safe Direction (SDI)
● Safe Speed Monitor (SSM)
Whether an inverter has extended functions gen‐
erally depends on the Control Unit hardware. The
corresponding inverters have an "F" at the end of
the product name, e.g. Control Unit CU240E‑2 F.
For SINAMICS G120 with a CU250S‑2 Control
Unit, you require a license for the extended func‐
tions.
