PHASE MOVE
This is a simple trapezoidal relative move
function, which acts on each rising edge of
the Enable input. The slave shaft is moved a
fixed distance at a rate given by the
VELOCITY parameter. A move must be
complete before a new move will be
registered.
If Register Mode is enabled, the MARK
OFFSET is also effected.
The move operation is aborted by the RESET (TOTAL) and POSITION ENABLE parameters
in the PHASE CONTROL function block.
The move opertion will automatically generate a velocity feed forward signal. It is important to
verify that is correct. The PHASE PID function block output, PID OUTPUT, should remain
near zero. If this is not the case, check the MAX SPEED parameter in the PHASE
CONFIGURE function block.

Parameter Descriptions
ENABLE
Range: FALSE / TRUE
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.
DISTANCE
Range: -3000.0 to 3000.0
The course distance that the move command will add to the phase loop.
DISTANCE FINE
Range: -1.0000 to 1.0000
Additional distance to allow fine control of position.
VELOCITY
Range: 0.10 to 300.00
The maximum velocity at which the distance is added to the phase loop, set in units per second.
ACCELERATION
Range: 0.10 to 3000.00
The acceleration at which the distance is added to the phase loop, set in units per second².
ACTIVE
Range: FALSE / TRUE
TRUE while the block is Active, i.e. the move distance is none zero.
DISTANCE LEFT
Range: —.xx
Diagnostic showing the distance remaining before the move is complete.
