11.8.1 Internal interfaces | "LS_PositionFollower" system block
The LS_PositionFollower system block provides the internal interfaces for the basic function
"Position follower" in the function block editor.
Inputs
Outputs
Note!
Ensure that the system block is called in a cyclic application task.
Basically, projects which only contain an unsolicited task and no cyclic task are not
permissible!

Information/possible settings
PF_bEnable
C02689/1 | BOOL
Requesting control via the basic function
TRUE If no other basic function is active, a change-over to the "Position
follower active" function state is carried out, and the setpoints
defined are accepted.
TRUEFALSE If no other basic function takes over the control of the drive, the drive
is brought to standstill, i. e. a change-over from the active function
state "Position follower active" via the "Drive is stopped" function
state back to the basic state "Drive at standstill" is carried out.
PF_dnPositionSet_p
C02688/1 | DINT
Position setpoint in [increments]
PF_dnSpeedAdd1_s
C02686 | DINT
Speed feedforward control value in [rpm]
PF_dnSpeedAdd2_n
C02687/1 | DINT
Additional speed setpoint in [%]
• 100 % ≡ Motor reference speed (C00011
)
PF_dnAccAdd_x
C02685 | DINT
Motor acceleration
• For calculating the acceleration torque (for setting C00276
="0").
• Selection as speed variation/time in [rpm/s]
PF_dnTorqueAdd_n
C02687/2 | DINT
Additive torque feedforward control value in [%]
• 100 % ≡ motor reference torque (display in C00057/2
).
