u Safe Disable Function Description
The Safe Disable function can be utilized to perform a safe stop according to the IEC/EN
61800-5-2, stop category 0 (Uncontrolled stop by power removal). It is designed to meet the
requirements of the ISO/EN 13849-1, Safety Category 3, PL d, and IEC/EN 61508, SIL2.

motor is cut by stopping the switching of the output transistors in a safe way. “Hbb” is shown
on the display. Safe Disable is applicable for induction and permanent magnet motors.
