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.
TRUEFALSE 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 ).
