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
Velocity REAL -1.0 Final velocity:
Value < 0: Use preset value
Value = 0: Permitted
Value > 0: Final velocity
Acceleration REAL -1.0 Acceleration (increasing motor power):
Value > 0: Use the specified value
Value = 0: Only permitted if the axis
does not have to be accelerated in order to
reach its final velocity.
Value < 0: Use preset value
Deceleration REAL -1.0 Deceleration (declining motor power):
Value > 0: Use the specified value
Value = 0: Only permitted if the axis
does not have to be accelerated in order to
reach its final velocity.
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:
Value = 0: default in S7T Config *
Value = 1: Positive sense of direction
Value = 2: - not permitted at "MC_MoveVelocity" -
Value = 3: Negative sense of direction
Value = 4: Current sense of direction (last used
sense of direction)
CURRENT BOOL FALSE Maintaining the current velocity:
FALSE: "Maintain current velocity"
disabled
TRUE: the current velocity and direction
are maintained.
Used to terminate synchronous operation,
for example.
Input parameter Velocity is here ignored.
As soon as the axis resumes its motion
at the current velocity,
output InVelocity returns the value TRUE.
PositionControl BOOL TRUE Position-controlled mode (this parameter is neglected
for velocity axes)
This parameter allows you to set the position / velocity
control mode for position-controlled axes.
TRUE: Position-control mode
FALSE: Velocity-control mode
The axis must be enabled for position control in order
to operated in master mode.
