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

Information/possible settings
Data type
Activation of position/angle control
BOOL
FALSE Position/angle control deactivated.
TRUE Position/angle control activated.
Activate position difference as setpoint selection
• In order to position the motor shaft, the
BOOL
within the motor control function with the absolute position setpoint
dnPosSetValue_p or alternatively with the speed setpoint nSpeedSetValue_a and
the position difference dnDeltaPos_p.
FALSE Positioning with position setpoint dnPosSetValue_p.
TRUE Positioning with speed setpoint nSpeedSetValue_a and position
difference dnDeltaPos_p.
Position difference (following error input)
• Difference between setpoint position and actual position in [increments]
DINT
• Is used for position control
• Scaling: a revolution is displayed with 65536 increments or steps.
Absolute position setpoint in [increments]
• Is used for position control
DINT
• Scaling: a revolution is displayed with 65536 increments or steps.
Create a setpoint for the speed controller from the position setpoint
• For highly dynamic control systems, the setpoint for the speed controller can be
BOOL
created from the absolute position setpoint dnPosSetValue_p instead of the
speed setpoint nSpeedSetValue_a.
specification
TRUE Create a speed setpoint from the position setpoint.
• The absolute position setpoint dnPosSetValue_p is differentiated
and a speed value is created which is the setpoint for the speed
controller.
• Internal limitation of 65536 increments/ms.
In preparation - Input has no function at present time!
Adopt home position ("Homing on the fly")
BOOL
FALSE TRUE Adopt home position dnMotorRefOffset_p.

position control function can work
if bDeltaPosOn = TRUE.
