NOTICE
Material damage when using motors that are not short-circuit proof
When using motors that are not short-circuit proof, activating the external armature short-
circuit braking can damage these motors.
• Only use motors that are short-circuit proof.
• Use suitable resistors for short-circuiting.
Note
Consequences of incorrect parameterization
In case of incorrect parameterization (e.g., induction motor and external armature short-
circuit selected), fault F07906 "Armature short circuit / internal voltage protection:
Parameterization error" is output.
