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
TF_bEnable
C02699/1 | BOOL
Requesting control via the basic function
TRUE If no other basic function is active, a change-over to the "Torque
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 "Torque follower active" via the "Drive is stopped" function
state back to the basic state "Drive at standstill" is carried out.
TF_dnTorqueSet_n
C02698/1 | DINT
Torque setpoint in [%]
• 100 % ≡ motor reference torque (display in C00057/2 ).
TF_dnSpeedHighLimit_n
C02698/2 | DINT
Upper speed limit value in [%] for speed limitation
• For positive direction of motion.
• 100 % ≡ Motor reference speed ( C00011 ).
• Negative values are limited internally to the value "0".
TF_dnSpeedLowLimit_n
C02698/3 | DINT
Lower speed limit value in [%] for speed limitation
• For negative direction of motion.
• 100 % ≡ Motor reference speed ( C00011 ).
• Positive values are limited internally to the value "0".
