8400 StateLine C | Reference manual
Basic drive functions (MCK)
Internal interfaces | System block "LS_MotionControlKernel"
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 (
LS_MotorInterface
).
bPosCtrlOn
Inputs have no function on the 8400 StateLine!
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
C00105
, the motor
is brought to a standstill (n
act
= 0).
• A pulse inhibit (CINH) is set if the auto DCB function has been
activated via
C00019
.
•
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.
•
C00159
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
