MOVE TO MASTER
SETUP::PHASE CONTROL::MOVE TO MASTER
Performance Level = ADVANCED : CLOSED-LOOP VEC Motor Control Mode only.
The FireWire option card (Option B) must be fitted to the drive.
This block provides a command which when executed will start a trapezoidal move that aligns the load position with the
Master Position + Total Offset. The Dist To Master is loaded such that there is a zero position error at the moment the position
loop is enabled. This prevents the shaft moving when the position loop is enabled.
Parameter Descriptions
ENABLE
This parameter commands the Move To Master function to start on positive edge.
MOVE METHOD
This parameter defines how the move will be performed, either Forwards, Backwards, or taking the Shortest distance.
Enumerated Value : Move Method
DIRECTION BAND
This parameter defines the move distance for which the Shortest move will always be taken, overriding the Forward and
Backward options of Move Method. This parameter is scaled such that 1.0 = 1 load mechanical revolution.
VELOCITY
This parameter defines the maximum velocity of the move, set in percent of maximum load speed.
ACCELERATION
This parameter defines the maximum acceleration of the move, set in percent of maximum load speed per second.
