Internal interfaces | "LS_Brake" system block
The LS_Brake system block provides the internal interfaces for the basic function "Brake control" in
the function block editor.
Inputs
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
BRK_bReleaseBrake
| BOOL
Releasing/applying the brake in connection with the selected operating mode
FALSE Apply brake.
• During automatic operation, the internal brake logic controls the
brake.
TRUE Release brake.
• In automatic operation the internal brake logic is deactivated and
the brake is released. This controller inhibit that may be set by the
brake control is deactivated again.
BRK_bStartingTorque2
| BOOL
Selection of the torque feedforward control value
• For the general use of the parameterisable starting torque as a feedforward
control value, the setting
= 0 is required.
Torque feedforward control ( 532)
FALSE Starting torque 1 (
) is active.
TRUE Starting torque 2 (
) is active.
BRK_bDisableStop
| BOOL
Prevent the brake from being applied in automatic operation
• By this the drive remains position-controlled in the function states "Quick stop
active", "Drive is stopped", and "Drive at standstill".
• The input has no effect when the controller is inhibited.
TRUE The application of the brake in automatic operation is prevented.
BRK_dnTorqueAdd_n
| DINT
Additive torque value in [%] for torque feedforward control during start
• 100 % ≡
Torque feedforward control ( 532)
Note:
The input is read out if the brake receives a release signal, e.g. when
BRK_bReleaseBrake = TRUE.
