Parameter Descriptions

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 Ambient Temperature

DriveAmbientTemp

This parameter should be set to reflect the ambient air temperature near the drive heatsink during normal operation. This will determine the amount of regenerative power that can be dissipated by the EN drive's internal shunt resistor. When that calculated value is exceeded by the Shunt Power RMS parameter a shunt fault will occur. Valid only for EN-208 and EN- 214 drives.

Drive Analog Output Feedback

DriveAnalogOutput.#.Feedback

Displays the Output voltage from one of the two analog outputs found on the 3-pin connector on the front of the drive or on the drive command connector.

Drive Enable Status

DriveEnableStatus

This source is active when the drive is enabled.

Drive Input Debounced

DriveInput.#.Debounced

This displays the state of the input after the debounce is taken into account.
