Input parameters
Parameter Data type Start value Description
Axis INT 0 Number of the technology DB
Execute BOOL FALSE Start of the command at the positive edge
Position REAL 0.0 Target position (negative or positive)
Velocity REAL -1.0 Maximum velocity (is not always reached):
Value > 0: Use the specified value
Value = 0: Not permitted
Value < 0: Use preset value
Acceleration REAL -1.0 Acceleration (increasing motor power):
Value > 0: Use the specified value
Value = 0: Not permitted
Value < 0: Use preset value
Deceleration REAL -1.0 Deceleration (declining motor power):
Value > 0: Use the specified value
Value = 0: Not permitted
Value < 0: Use preset value
Jerk REAL -1.0 Jerk:
Value > 0: Use the specified value
Value = 0: Use trapezoidal motion profile
Value < 0: Use preset value
Direction INT 0 Direction preset for modulo axes:
Value = 0: default in S7T Config *
Value = 1: Positive sense of direction
Value = 2: Shortest distance
Value = 3: Negative sense of direction
Value = 4: Current sense of direction (last used
sense of direction)
Mode INT 0 Override mode:
Value = 0: Override motion:
The current motion is canceled
Value = 1: Append motion:
The motion command is written to the
command buffer the axis is stopped at the
motion transition
Value = 2: Overlay motion:
The motion command is written to the
command buffer the motion transition is
overwritten
DoneFlag INT 0 DoneFlag generated in the MCDevice DB
* Selection of the direction with "Determine based on sign of velocity setpoint" in
the default setting of S7T Config is not useful, because negative velocity
setpoint values can not be set at input parameter Velocity.
