8.12.1 Internal interfaces
In the function block editor, the LS_MotionControlKernel
system block provides the
following internal interfaces for the basic function "holding brake control":
Inputs
Outputs
Identifier
Data type
Information/possible settings
bBrkRelease
BOOL
Releasing/applying the brake in connection with the selected operating mode
FALSE Apply brake.
• During automatic operation, the internal brake logic controls of
the brake.
TRUE Release brake manually (forced release).
• 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.
bBrkStartTorqueDir
BOOL
In preparation - Input has no function at present time!
Precontrol direction during starting
TRUE Invert precontrol magnitude nBrkTorqueAdd_a.
nBrkTorqueAdd_a
INT
Additive torque value in [%] for torque precontrol on starting
• For SC (servo control) mode
• 100 % ≡ maximum torque (C00057
)
Torque precontrol during starting
bBrkApplied
BOOL
In preparation - Input has no function at present time!
Feedback signal - switching state of holding brake
TRUE Brake has been activated (waiting times have expired).
Identifier
Data type
Value/meaning
bBrkReleaseOut
BOOL
Trigger signal for switching element holding brake control via a digital output
• Use bit 0 under C02582
to activate inverted switching element triggering.
Functional settings
FALSE Apply brake.
TRUE Release brake.
bBrkReleased
BOOL
Brake control status signal with consideration of the application and release time of
the brake
FALSE Brake applied (when the brake application time has elapsed).
TRUE Brake released (when the brake release time has elapsed).
Stop!
The digital outputs are not suitable for the "direct" control of a holding brake!
• Connect the digital output connected to the trigger signal bBrkReleaseOut
with a relay or power contactor which switches the brake supply.
• When a power contactor is used, the response and release time of the earth
contact is added to the response and release time of the brake.
