Safe Disable Specifications

The Safe Disable input provides the stop function that complies with "Safe Torque Off" as specified by IEC/EN
61800-5-2. The Safe Disable input meets the requirements of ISO/EN ISO 13849-1 and IEC/EN 61508. It also has
a safety status monitor to detect safety circuit errors.
When you install the drive as a component in a system, you must make sure that the system complies with the
applicable safety standards.
