Commutation Angle Correction
CommutationAngleCorrection
The difference between the electrical angle as determined at power up from the U, V, and W commutation tracks and the electrical angle as
determined from the marker pulse or UVW transitions. This value will be zero until the marker pulse is detected or UVW transition is detected.
Commutation Track Angle
CommutationTrackAngle
This parameter is derived directly from the state of commutation tracks and the Encoder U Electrical Angle parameter.
Commutation Voltage
CommutationVoltage
This parameter is used to determine commutation angle accuracy. When queried it returns the value of the direct axis voltage. The value is
given as a percentage of 1/2 the bus voltage.
Decelerating
Decelerating
This source is active when the drive is decelerating. A normal index consists of 3 segments: Accelerating, At Velocity, and Decelerating.
Decelerating follows the accelerating segment and the At Velocity segment. When indexes are compounded to create a complex motion
profile, only the last index may contain a decelerating segment.
Define Home
DefineHome
This destination is used to set the Commanded Position to the value specified in the DefineHomePosn variable. On the rising edge of this input
function the absolute position is set equal to the DefineHomePosn and the AbsolutePosnValid output function (source) is activated.
Define Home Position
DefineHomePosn
This is the value to which the position command will be set when the Define Home Destination is activated, This is used in applications that do
not use a home routine, but is required to define a known reference point.
Acceleration
DistanceRecovery.Accel
This parameter in user units is the acceleration rate for the distance recovery index.
Deceleration
DistanceRecovery.Decel
This parameter in user units is the deceleration rate for the distance recovery index.
Enable Distance Recovery
DistanceRecovery.DistanceRecoveryEnable
Select the check box to enable the additive distance recovery index feature.
Velocity
DistanceRecovery.Vel
This parameter in user units is the velocity limit of the distance recovery index.
Characteristic Distance
DistUnits.CharacteristicDistance
This parameter is the distance the load travels (in user units) when the motor travels the characteristic length (in motor revolutions). This
parameter is used along with the DistUnits.CharacteristicLength to establish the relationship between user distance and actual motor travel
distance. See the section on the User Units View in the Setting Up Parameters chapter.
Characteristic Length
DistUnits.CharacteristicLength
This parameter is the distance the motor travels (in whole number of revolutions) to achieve one characteristic distance of load travel. This
