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 “User Units View” on page 37.

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 “User Units View” on page 37.

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 decimal places set in this parameter determines the number of decimal places used in all distance parameters throughout the software. You can select from zero to six decimal places of accuracy.

Distance Units Name

DistUnits.Name

This is a text variable which is used as the label for the distance/position user units. It can be up to 12 characters in length.

Drive Active

DriveActive

The DriveActive event, when active, indicates that the bridge on the Unidrive SP is closed (drive is enabled). This parameter is read-only, and is read directly from parameter

10.02in the Unidrive SP database. If/When a drive trip occurs, this parameter will deactivate automatically.

Drive Enable Status

DriveEnableStatus

This source is active when the drive is enabled.

Drive Healthy

DriveHealthy

The Drive Healthy signal indicates that the drive is not in the trip state. This bit is active when no trip is active. On activation of a drive trip, this signal will deactivate automatically. When the trip is cleared, Drive Healthy will activate again.

Drive Serial Number

DriveSerialNumber

This displays the serial number of the Drive to which the SM-EZMotion module is attached.

Reset Errors

Error.Reset

Resets errors that do not require a power down. This event is "or"ed with the reset button on the drive.

SM-EZMotion I/O Status Word

EZConnect.DigitalIOReadWord

This parameter is a bitmap that contains the status of the digital I/O on the SM-EZMotion module. This parameter is read-only and is used to control the virtual LED’s on the EZMotion I/O Setup view.

EZInput Debounce Time

EZInput.#.DebounceTime

The digital inputs on the SM-EZMotion module can be debounced to reject electrical noise on a wire or switch bounce. When an input activates, it must be active for at least the specified Debounce Time before the input is
