11.12.1 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

C02609/1 | 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

C02609/2 | BOOL

Selection of the torque feedforward control value

• For the general use of the parameterisable starting torque as a feedforward

control value, the setting C02588

= 0 is required.

Torque feedforward control

( 532)

FALSE Starting torque 1 (C02586

) is active.

TRUE Starting torque 2 (C02587

) is active.

BRK_bDisableStop

C02609/10 | 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

C02608 | DINT

Additive torque value in [%] for torque feedforward control during start

• 100 % ≡ C00057/2

Torque feedforward control ( 532)

Note:

The input is read out if the brake receives a release signal, e.g. when

BRK_bReleaseBrake =TRUE.
