11.10.4 Activating setpoint interface
Requirements
• The controller is in the "Operation" device state.
• The basic function "Torque follower" is part of the active application.
• No other basic function is active.
Activation
To request the control via the basic function, the TF_bEnable enable input in the application must
be set to TRUE.
• If no other basic function is active, a change-over to the "Torque follower active" function state
is carried out, and the motor control is automatically switched over to torque control with speed
limitation. Setpoints can now be defined via the corresponding inputs.  Signal flow
• A successful change to the function state "Torque follower active" is displayed by a TRUE signal
at the TF_bEnabled status output.
Deactivation
When the TF_bEnable enable input is reset to FALSE, the setpoint inputs are inhibited. If the drive is
not at standstill, it is braked to standstill within the deceleration time set for stop unless another
basic function takes over the control of the drive.
• The status output TF_bEnabled is reset to FALSE and a change-over from the active "Torque
follower active" function state via the "Drive is stopped" function state back to the basic state
"Drive at standstill" is carried out.

Stop!
The basic function does not take over the control of the drive from the current speed, but
immediately with the setpoint defined, which may cause a jerk!
