9.7.3 Activating setpoint interface
Requirements
r The controller is in the device state "Operation".
r The basic function "Position follower" is part of the active application.
r No other basic function is active.
Activation
To request the control via the basic function, the enable input PF_bEnable in the
application must be set to TRUE.
r If no other basic function is active, it is changed to the function state "Position follower
active". Setpoints can now be specified via the corresponding inputs. Signal flow
r A successful change to the function state "Position follower" is displayed by a TRUE
signal at the status output PF_bEnabled.
Deactivation
When the enable input PF_bEnable 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.
r The status output PF_bEnabled is reset to FALSE and a changeover from the active
function state "Position follower active" via the function state "Drive is stopped" back
to th basic state "Drive in standstill" is effected.

Stop!
The basic function takes over the control of the drive not from the current speed
on but directly with the defined setpoint which may lead to a jerk!
