the corresponding bit location of BitRegister.#.Value (by setting the bit location to 1) or to clear the current data in BitRegister.#.Value (by setting the bit location to 0).

Unidrive SP Braking Resistor Overload Accumulator

BrakeOverloadAccumulator

This parameter gives an indication of braking resistor temperature based on a simple thermal model. The formula for the thermal model is a function of parameters

10.30and 10.31 (set in the initialization file). A value of zero indicates that the resistor is close to ambient, and a value of 100% is the maximum temperature (trip level). An OVLd warning is given if this parameter is above 75% and the braking IGBT is active. This parameter can be found on the Online tabs of the Status and Current views.

Unidrive SP Braking Resistor Alarm

BrakeResistorAlarm

This parameter is set when the braking IGBT is active and the braking overload accumulator is greater than 75%. This parameter when activated is automatically kept active for

0.5seconds so that it can be displayed on the keypad

display. This parameter can be found on the Online tabs of the Status and Current views.

Unidrive SP Bus Voltage

BusVoltage

This read-only parameter displays the instantaneous voltage value of the DC bus in the Unidrive SP. This parameter is found on the Online tab on the Status view and is read directly from parameter 5.05 in the Unidrive SP database.

Capture Enable

CaptureEnable

The CaptureEnable is used to enable or “arm” the capture component. If the CaptureEnable is not active, then the CaptureActivate has no effect, and the CaptureTriggered remains inactive. Once the CaptureEnable is activated, the Capture component is ready and waiting for a CaptureActivate signal to capture data. CaptureEnable is a read-only destination on the Assignments view, and is accessible through a user program.

Capture Activate

CaptureActivate

If the Capture component is enabled and has been reset (CaptureTriggered is inactive), then the rising edge of CaptureActivate will capture the four data parameters and cause CaptureTriggered to be activated. If the Capture component is not enabled, or has not been reset, the CaptureActivate will be ignored.

Capture Reset

CaptureReset

The CaptureReset is used to reset or re-arm the capture component after it has been activated. If the capture has been activated, the CaptureTriggered destination will be active. The capture component cannot capture data again until it has been reset. The capture component will automatically reset itself if the CaptureEnable signal is removed.

Capture Triggered

CaptureTriggered

The CaptureTriggered signal is read-only and indicates that the Capture component was activated and that data has been captured. CaptureTriggered will activate on the leading edge of CaptureActivate if the Capture component is enabled and reset. Capture Triggered will remain active until CaptureReset is activated.

Name

Capture.Name

You can assign a descriptive name to each capture, making the setup easier to follow. The length of the text string is limited by the column width with a maximum of 12 characters. Simply double click on the Name field of any capture’s line to assign a name to it.

Number

Capture.Number

This parameter defines the size of the Capture list.

Captured Time

Capture.#.CapturedTime

The time, in microseconds, from a free-running 32-bit binary counter at which CaptureTriggered activated.

Captured Position Command

Capture.#.CapturedPositionCommand

The command position, in user units, at the time when CaptureTriggered activated.

Captured Position Feedback

Capture.#.CapturedPositionFeedback

The feedback position, in user units, at the time when CaptureTriggered activated.

Captured Master Position

Capture.#.CapturedMasterPostion

The master axis feedback position, in master axis distance
