FB_BA_MotMdltExt

The template is used to control a speed-controlled motor. It consists essentially of the base class FB_BA_MotMdlt.

The difference to the template FB_BA_MotMdlt is the AV object Sp with the associated MAX selection. A minimum control value for the motor could thus be specified via the Sp object.

	The initialization of the template takes place within the method FB_Init.
