Functional Safety Overview
6.8.1
Select and apply the components in the safety control system appropriately to achieve the required level of operational safety.
Before integrating and using STO in an installation, carry out a thorough risk analysis on the installation to determine whether the
STO functionality and safety levels are appropriate and sufficient.
This parameter group contains non-safety-related parameters. They are used to configure the behavior of the drive after a functional
safety event (for example, STO). Refer to Functional Safety Operating Guide for more information.

Safe Torque Off (STO)
6.8.3
The Safe Torque Off (STO) function is a component in a safety control system. STO prevents the unit from generating the power required
to rotate the motor. The iC7 drives are available with:
Safe Torque Off (STO), as defined by EN IEC 61800-5-2.
l
Stop category O, as defined in EN 60204-1.
l
STO Activation
The STO function is activated by removing the voltages at the STO inputs of the drive. By connecting the frequency converter to external
safety devices providing a safe delay, an installation for a Safe Stop 1 can be obtained. External safety devices must fulfill the required
Cat.IPL or SIL when connected to STO inputs.
With default settings, the drive issues a fault, trips the unit, and coasts the motor to a stop when the STO function is activated. A manual
restart is required to continue operation. Use the STO function to stop the drive when a safety function is required. In normal operating
mode when STO is not required, use the standard stop function instead.
