8910 Reference value invalid

Description

Device reactions	Default reaction	Minimum reaction
Drive	BD1	E
Power supply	-	-

A position reference value was transferred via the Sercos real-time channel which cannot be reached within a Sercos cycle.

Cause	Solution
The function FC_SetRefPosFromPos() was called up for an axis that is under control and follows the reference values (AxisState >=3). By that the resulting jump in the reference position must be large enough so that a reference velocity is calculated, which is twice as large as the parameter MaxVel.	oUse FC_SetRefPosFromPos() in the AxisState < 3. oSet FC_SetRefPosFromPos() to a position that leads to a smaller jump, regarding the current reference position.
An incorrect reference position was calculated in the controller.	Contact your Schneider Electric representative.
