This FB serves to implement the following positioning functions:
• Bring drive to curve position (e.g. after mains connection, manual jog, homing)
• Release drive from curve and bring it to safe position (position override function)
• Positioning the X axis via X offset (higher-level positioning)
• Positioning the Y axis via Y offset (higher-level positioning)

Information/possible settings
bExecute
BOOL
Execute positioning profile
• Only possible if the bEnable input is set to TRUE.
FALSE No positioning/positioning is aborted.
• The speed at the nNOut_v output is braked to standstill via the
deceleration ramp set in C01060/4 (nNOut_v = 0).
• At the same time, the dnPosOut_p output is stopped.
FALSETRUE Positioning is executed/continued.
• In case of an activated limit stop ( C01058/2 = TRUE), a renewed
positive edge for a following positioning procedure is required.
bSetPos0
BOOL
Travel to zero position
• Only possible if the bEnable input is set to TRUE.
FALSE The value at the dnSet_p input is used as setpoint position.
TRUE The value at the dnSet_p input is ignored. The setpoint position is
internally set to "0" and the dnPosOut_p output can be travelled to
zero position.
