MC_ MoveVelocity
Velocity instruction
10MC11T
Explanation of the Instruction:
MC_MoveVelocity is applied to control the terminal actuator to move at the given acceleration and
deceleration and finally it moves at the constant speed when reaching the given velocity. The execution of
this instruction is completed after the speed of terminal actuator reaches the given speed but terminal
actuator will still keep moving at this speed.
Explanation of input and output parameter of the instruction:

M,I,Q,
Constant
Velocity
The running speed of terminal actuator and it is always
positive.(Unit: unit/second)
REAL Constant, D

Acceleration of terminal actuator and this parameter is
always positive.(Unit: unit/second2)
REAL Constant, D
Deceleration
Deceleration of terminal actuator and this parameter is
always positive.(Unit: unit/second2)

Direction
Direction for servo motor rotation
1: positive direction;
-1: negative direction;
2: keeps the current direction ( The current rotation
direction is positive when the motor stops.)
INT Constant, D

“Invelocity” bit is on when servo motor reaches the target
position; “Invelocity” bit is reset when “Execute” turns On
Æ Off.
BOOL M,Q
Abort
When the execution of this instruction is interrupted before
it reaches the target speed, "Abort" turns on;
when “Execute” turns off, “Abort” is reset;
when other instruction is executed after the velocity of this
instruction reaches the given velocity, “Abort” of this
instruction will not turn on.
BOOL M,Q
