In the interconnection previously shown, the Motion Control Kernel monitors every interface. Some
of the signals such as a quick stop request or a DC-injection braking request are directly passed
through to the motor control. However, other signals are passed through or modified depending on
the operating mode (e.g. synchronising a setpoint selection via ramp function).

Internal interfaces | System block "LS_MotionControlKernel"
In the Function Block editor, the system block LS_MotionControlKernel provides the interfaces to
the Motion Control Kernel.

Control and setpoint signals for motor control
The purpose of the following inputs is to transfer control signals and setpoints to the internal motor control
function (
bPosCtrlOn
Inputs of 8400 StateLine have no function!
bDeltaPosOn
dnDeltaPos_p
dnPosSetValue_p
bPosDerivativeOn
bMotorRefOffsetOn
dnMotorRefOffset_p
bQspOn
BOOL
Trigger quick stop (QSP) via the MCK
• Also see device command "
Activate/deactivate quick stop
".
TRUE Activate quick stop
• Motor control is decoupled from the setpoint selection and,
within the deceleration time parameterised in
, the motor
is brought to a standstill (n
act
= 0).
• A pulse inhibit is set if the auto-DCB function has been activated
via
.
•
The motor is kept at a standstill during closed-loop operation
(function in preparation).
FALSE Deactivate quick stop
• The quick stop is deactivated if no other source for the quick stop
is active.
•
displays a bit code of active sources/causes for the quick
stop.
nPWMAngleOffset
INT
Angular offset input
• Scaling: 16384 ≡ 100 %
• Setting range: 0 ... 199.99 %
bSpeedCtrlIOn
BOOL
Directly set the I-component of speed controller
• In order to statically specify a minimum torque, e.g. when a load is being lifted.
TRUE Se the I-component of the speed controller to the value
nSpeedCtrlI_a.
nSpeedCtrlI_a
INT
I-component of the speed controller
• Value is adopted in the case of a FALSE-TRUE edge at the input bSpeedCtrlIOn.
nSpeedSetValue_a
INT
Rotation speed/velocity setpoint
bTorquemodeOn
BOOL
TRUE Switch on torque-controlled operation
nTorqueSetValue_a
INT
Torque setpoint
