Orient Start
Specifies how far before the target position that the orient deceleration
begins. The data variable is expressed in spindle degrees prior to the
target.
Data Range: DEG 000.0 to 359.9
Default Value 45.0
In-Position
In-Position specifies how close the actual spindle position must be to the
target position before the In-position output is energized. If the spindle
were to move outside of this in-position range after the output was
initially energized, the output would again turn Off. The data is expressed
in spindle degrees away from the target.
Data Range: +DEG 000.000 to 359.999
Default Value 000.250
Dir From Stop
This parameter specifies the direction of spindle rotation when
performing an orient operation from stop. The scroll selection for this
variable specifies the direction of rotation if the Zero Speed output was
On when the Orient Command was input.
If “SHORTEST” is selected, the spindle will rotate in the direction that
gives the shortest distance to the orient position. It may rotate either
clockwise or counterclockwise.
If the spindle is rotating (the Zero Speed output is not On) when the
Orient Command is input, the orient operation always continues in the
same direction of rotation as it was moving prior to receiving the
command.
Possible Choices: CCW, CW, SHORTEST
Default Value
CCW
Hold Position
Determines whether or not the motor will continue to produce torque to
hold the spindle within the in-position band once the orient function has
been completed.
Possible Choices: TORQUE HOLD, TORQUE OFF
Default Value
TORQUE HOLD
