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 
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 
DoneFlag  INT  0  DoneFlag generated in the MCDevice DB 
If the value for Deceleration > +1E+12, the axis is decelerated with the maximum 
delay. 
If the value for Jerk > +1E+12, the axis is decelerated with the maximum jerk. 
!
Warning 
If a numerical value which can not be represented as a REAL value is specified at 
the Deceleration or Jerk input parameter, MC_Stop is not executed.
