Basic drive functions
Speed follower | Activating setpoint interface
194 Firmware 1.37 - 09/2006 L
9.8.3 Activating setpoint interface
Requirements
r The controller is in the device state "Operation".
r The basic function "Speed 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 SF_bEnable in the
application must be set to TRUE.
r If no other basic function is active, it is changed to the function state "Speed follower
active" and the motor control is automatically switched to speed control with torque
limitation. Setpoints can now be defined via the corresponding inputs.Signal flow
r A successful change to the function state "Speed follower active" is displayed by a TRUE
signal at the status output SF_bEnabled.
Deactivation
When the enable input SF_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 SF_bEnabled is reset to FALSE and a changeover from the active
function state "Speed 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!
