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 Po 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
PREF: 124.01 Default: FALSE Range: FALSE / TRUE
This parameter commands the Move To Master function to start on positive edge.
MOVE METHOD PREF: 124.02 Default: 0 Range: See below
This parameter defines how the move will be performed, either Forwards, Backwards, or taking the Shortest distance.
Enumerated Value : Move Method
0 : SHORTEST
1 : FORWARD
2 : BACKWARD
DIRECTION BAND PREF: 124.03 Default: 0.05 Range: 0.00 to 200.00
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
PREF: 124.04 Default: 1.00 % Range: 0.10 to 300.00 %
This parameter defines the maximum velocity of the move, set in percent of maximum load speed.
ACCELERATION PREF: 124.05 Default: 1.00 % Range: 0.01 to 3000.00 %
This parameter defines the maximum acceleration of the move, set in percent of maximum load speed per second.
