
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.
• During automatic operation, the internal brake logic is
deactivated and the brake is released. If the brake control has
inhibited the controller, this inhibit 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 ( 564)
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 ( 564)
BRK_bBrakeApplied
C02609/3 | BOOL
Input for status detection via switching contacts at the brake
• Activation of the input by setting C02583 = 1.
 Signal configuration ( 555)
FALSE Status "Brake is released".
TRUE Status "Brake is applied".
