AC890PX AC Drive
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 PREF: 109.01 Default: FALSE 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.
HOLD PREF: 109.08 Default: FALSE Range: FALSE / TRUE
Command to hold the current move. (In this state a new move may be triggered, replacing the held move)
RESET PREF: 109.11 Default: FALSE Range: FALSE / TRUE
When True, this input aborts the current Move, and if the position loop is not operating, resets the Offset to zero.
DISTANCE PREF: 109.02 Default: 1.0 Range: -3000.0 to 3000.0
Sets the homing distance in revolutions, a revolution calculated from the number of lines on the encoder and maximum speed.
DISTANCE FINE
PREF: 109.03 Default: 0.0000 Range: -1.0000 to 1.0000
Fine adjustment of homing distance. The actual homing distance is the sum of DISTANCE and DISTANCE FINE.
VELOCITY PREF: 109.04 Default: 1.00 % 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 PREF: 109.07 Default: 1.00 % Range: 0.01 to 300.00 %
The acceleration at which the distance is added to the phase loop, set in units per second
