9.2 Drive Functions

A prerequisite for the use of the external armature short circuit is the use of a permanent-

magnet synchronous motor (p0300 = 2xx).

Only short-circuit proof motors may be used, or suitable resistances must be used for short-

circuiting the motor.

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.
