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

This source is active when the module or 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

The DefineHome parameter is used to set the motors absolute position to the value stored in the DefineHomePosn variable.

On the rising edge of the DefineHome function the Commanded Position is set equal to the DefineHomePosn and the

AbsolutePosnValid source is activated.

Characteristic Distance

DistUnits.CharacteristicDist

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 parameter is used along with the DistUnits.CharacteristicDist to establish the relationship between user

distance and motor travel distance. See the section on the User Units View in the Setting Up Parameters chapter.

Distance Decimal Places

DistUnits.Decimal

This parameter is used to select the number of decimal places used in the DistUnits.CharacteristicDist. Using a high number

of decimal places will improve positioning resolution, but will also limit the maximum travel distance. The number of
