Why does my SEW MDX61B stay stuck at 0?

The MDX61B may fail to leave state 0 due to logic power issues, gate driver failure, or a power-stage fault.

What causes an MDX61B not to change to state 1?

A faulty control board, missing internal supply voltages, or startup sequence errors usually prevent the transition from 0 to 1.
