Four safety options are available for the PowerFlex 750-Series drives:

• Safe Torque Off
• Safe Speed Monitor
• Integrated Safety - Safe Torque Off
• Integrated Safety Functions

Safe Torque Off is ideal for safety-related applications that require the removal of rotational power to the motor without shutting down the drive. Safe Torque Off functionality offers the benefit of quick start-up after a demand on the safety system. Safe Torque Off helps reduce wear from repetitive start-up and provides safety ratings up to and including SIL CL3, PLe, and category 3.

Safe Speed Monitor is ideal for applications where the speed is controlled and monitored. The Safe Speed Monitor option combines Safe Torque Off capability with integrated safety relay functionality and the Safe Speed control technology in one hardware option. The Safe Speed Monitor option provides safety ratings up to and including SIL CL3, PLe, and category 4.

With the Safe Speed Monitor option, you can safely monitor and control your application's speed, allowing operators to perform process or maintenance work without stopping the machine.

The Integrated Safety - Safe Torque Off (STO) option module provides a hardwired or a networked STO function via an Ethernet/IP network.
