PHASE MOVE
SETUP::PHASE CONTROL::PHASE MOVE
Performance Level = ADVANCED : CLOSED-LOOP VEC Motor Control Mode only.
The FireWire option card (Option B) must be fitted to the drive.
This function block uses a position loop to stop the drive in a set distance. The distance is set in revolutions based on the
number of lines on the encoder, usually from a mark at a fixed distance from the home position.
For accurate positioning the drive must be in Closed Loop Vector mode, if the drive is in any other mode then an open loop
home algorithm will be used.
Parameter Descriptions
ENABLE
If the function block is not already Active, ENABLE starts the Move operation when going from FALSE to TRUE. Setting
ENABLE to FALSE while a move is active will NOT abort the operation.
HOLD
Command to hold the current move. (In this state a new move may be triggered, replacing the held move)
RESET
When True, this input aborts the current Move, and if the position loop is not operating, resets the Offset to zero.
DISTANCE
Sets the homing distance in revolutions, a revolution calculated from the number of lines on the encoder and maximum speed.
DISTANCE FINE
Fine adjustment of homing distance. The actual homing distance is the sum of DISTANCE and DISTANCE FINE.
VELOCITY
The maximum velocity at which the distance is added to the phase loop, set in units per second.
