Marker Offset
P1-03= 0
P1-03 Orient offset distance Q Q Q Q
The marker offset contains the number of quadrature pulses or counts offset past the marker position that the shaft will
travel before stopping at the orient position. When this value is 0 the shaft will stop at the marker position. The desired
value may be found by running the drive and energizing the orient input. When the drive stops de-energize the run and
orient inputs. Rotate the shaft to the desired position by hand or by jogging the drive using the run inputs. Read the
value of U1-50: Marker Offset and enter it here.
The value of U1-50 is a rolling counter ranging from 0 to the number of quadrature counts per revolution. The direction
of rotation is irrelevant. The value indicates an absolute position to the marker position and is the same in either
direction.
This value may also be used to add counts to the positioning algorithm. Adding the number of positioning encoder
quadrature counts per revolution increases the stopping distance by one revolution.
Position Speed
P1-04= 0.10 HZ
P1-04 Position Speed Q Q Q Q
The position speed is the minimum speed that may be used during positioning. This speed is also used when the shaft is
within the number of quadrature counts set in P1-05: Position Count of the orient position. If this speed is set to high the
drive will oscillate when trying to hold the orient position. The positioning algorithm will decrease the speed until zero
speed is reached at the orient position or this speed is reached and maintained until the orient position.
Position Count
P1-05= 0
P1-05 Position Count Q Q Q Q
The position count is the number of quadrature counts before the orient position that the drive will hold the speed set in
P1-04: Position Speed. This may be used to prevent overshooting the orient position. If this count is set to high the
drive will slow down to soon and cause extended positioning times.
Stop Count
P1-06= 0
P1-06 Stop Count Q Q Q Q
The stop count is the number of quadrature counts before and after the actual orient position that will not result in a
correction. This creates a stop range that prevents oscillation while the drive is in zero servo. The effect of this is
dependent on the position encoder’s resolution.
