xActivate

Data type – BOOL

• TRUE – Activate function
• FALSE – Deactivate function. The outputs of the function block are reset, causing the drive to stop with the deceleration set in the application limits.

xEnableApplicationStop

Data type – BOOL

• TRUE – Drive is enabled
• FALSE – Drive is stopped with lrLineSpeedStopDec (ST_Config_General)

xUnwinder

Data type – BOOL

• TRUE – Activate operation as unwinder
  INFORMATION: The direction of rotation must be specified opposite to the process direction.
• FALSE – Activate operation as rewinder

xPositive

Data type – BOOL

• TRUE – Activate positive rotation
• FALSE – Deactivate positive rotation

xNegative

Data type – BOOL

• TRUE – Activate negative rotation
• FALSE – Deactivate negative rotation

xStart

Data type – BOOL

• TRUE – Start winding
• FALSE – Stop winding

lrSetpointStartLineSpeed

Data type – LREAL

Rewinding speed in m/min

lrSetpointTension

Data type – BOOL

Setpoint tension in N

Can be influenced via the configuration values of the "winding characteristic" (ST_Config_TensionTorque).

lrSetpointRampTension

Data type – LREAL

Setpoint ramp tension in N/s

lrActualDiameter

Data type – LREAL

Current diameter in mm

lrActualLineSpeed

Data type – LREAL

Conductance current path speed in m/min

lrActualLineSpeedAcc

Data type – LREAL

Conductance acceleration current path speed in m/(min*s)

Only necessary if acceleration compensation (ST_Config_TensionTorque) is activated.

aFrictionTable

Data type – ARRAY [0..121] OF LREAL

Friction coefficient table

xDisableFrictionComp

Data type – BOOL

• TRUE – Friction compensation inactive
• FALSE – Friction compensation active

lrUserFriction

Data type – LREAL

External friction coefficient (1.0 = 100% M_setp)

With activated external friction coefficient (ST_Config_TensionTorque activated)

lrActualTensionSignal

Data type – LREAL

Actual tension, analog signal of a tension sensor, which must be scaled to [N] via the scaling of the actual value signal (ST_Conig_PID).

xPIDcontrollerOff

Data type – BOOL

• TRUE – PID controller inactive
  I component is deleted and the controller output is set to "0".
• FALSE – PID controller active

xPIDcontrollerHold

Data type – BOOL

• TRUE – PID controller stopped
  The controller output keeps the last calculated value.
• FALSE – PID controller active

Output signals drive

iActualInverterMode

Data type – INT

Current inverter status

xStandstill

Data type – BOOL

• TRUE – Drive at standstill
• FALSE – Drive is rotating

lrActualVelocity

Data type – LREAL

Current speed in min^-1

lrActualTorque

Data type – LREAL

Current torque in (1.0 = 100% M_setp)

stConfig

Data type – ST_Config_TensionTorque

Configuration of the torque control
