Motion Control Using the EASI Command Set
Move Types
Mechanical movement results from the motion of a motor shaft. By controlling the velocity,
acceleration, distance and direction of the motor, different move profiles can be created for
particular applications. Move types can be preset, meaning a move is made in a controlled
way over a specified distance, or continuous where only acceleration, velocity and direction
are defined, distance being ignored. Various move types can be selected using the mode
(M) command.
Preset Moves
Preset moves allow you to position a target or work-piece in relation to the motor's previous
stopped position (incremental moves) or in relation to a defined zero reference position
(absolute moves).
Absolute Preset Moves (MA)
An absolute preset move will move the shaft of the motor a specified distance from the
absolute zero position (MA).
Incremental Preset Moves (MI)
When the MODE command is used to select indexed move with incremental positioning (MI),
the motor shaft can be moved a specified distance from its starting position in either a
clockwise (CW) or counter clockwise (CCW) direction.
Note: a positive direction is defined as one resulting in clockwise (CW) rotation of the motor
shaft when viewed from the flange.
Continuous Moves (MC)
This mode is useful for applications which require constant travel of the load, when the motor
must stop after a period of time has elapsed rather than after a fixed distance, or when the
motor must be synchronised to external events such as trigger input signals (MC).
