Outputs

Parameter

bPosMode

BOOL

Positioning mode

FALSE Absolute positioning

• The setpoint at dnSet_p is the absolute setpoint position (with

regard to zero position):

TRUE Relative positioning

• With a FALSE/TRUE edge at the bExecute input, the outputs of the

current position (dnAct_p) are traversed by the dnSet_p value:

Note:

Only to be used with activated limit stop (

C01058/2

= TRUE)!

dnSet_p

DINT

Setpoint for positioning in [increments]

• Scaling: a revolution is displayed with 65536 increments or steps.

dnAct_p

DINT

Actual position in [increments]

• Connect this input with e.g. dnPosOut_p of this FB or with another FB which

outputs the actual position of the drive.

bEnable
