    Parameter Descriptions Parameter 0 – Exit to Running Mode When parameter 0 is selected in Parameter-Selection Mode, the unit will return to Running Mode and display the running value. This should be selected once the changes to the parameters are completed. Parameter 1 –...
  • Page 14 Parameter 13 – Decimal Point (DP) Position This selects the format of the display with respect to the decimal point’s position. This parameter does not affect the value entry for other parameters. The decimal point is only displayed in Rate modes.
  • Page 15 Parameter 22 – Display Value at Center Output This defines the center value for the display in bipolar (or bidirectional) modes of operation. In bipolar applications, this value should be set to the display value that corresponds to a null or zero output.
  • Page 16 Mode 3: Ouput Setpoint When S1 Low When the S1 input is at an electrically low state or wired to the unit's common, the DP4 will force its output to a percentage which corresponds to the programmed jog setpoint, parameter 31. Once the S1 input returns to an electrically high (+5V) state or allowed to float disconnected, the output will once again correspond to the display value.
  • Page 17 Mode 6: Output 100% When S2 High When the S2 input is at an electrically high (+5V) state or allowed to float disconnected, the DP4 will force its output to 100%. Once the S2 input returns to an electrically low state or wired to the unit's common, the output will once again correspond to the display value.
  • Page 18 Mode 3: Pulse & Auto Reset In this mode, the alarm output will pulse on and off until the alarm condition ceases to exist. The pulsed modes are commonly used for audible alarms where a constant output would be considered distracting or awkward. The alarm will automatically reset when the conditions return to normal.
  • Page 19 Parameter 48 – Alarm 1 Upper Limit This setting defines either the upper limit or upper end of a range for the alarm region. Alarm limits are set in display units without regard to decimal point or colon position. In Rate Mode, a limit of 123 could represent a display value of 123, 12.3, 1.23, or 0.123.

  • Page 20: Application Examples

    Application Examples User Interface for Industrial Conveyor Oven with AC Drive Description: An industrial tunnel oven currently uses an AC invertor drive with an attached speedpot to control the motor which drives its train. Because the process time for the oven is known, it is preferred that the user be able to set the process time in minutes and seconds on a digital display.
