#Parameter Changes

####CONFIGURATION/DRIVE PERSONALITY/Iarm BURDEN OHMS

  • PIN680 to ‘110.44’
    • Reduce the model (plx15) rating by 50% so it works with the 2HP motor
    • follow procedures on page 198 of the user manual
    • Note. After parameter PIN680 (Iarm BURDEN OHMS) has been altered, it will only apply after the following:
      1. Save the new value using the PARAMETER SAVE function.
      2. Turn the unit control supply off then back on again.
      3. Adjust- 2)RATED ARM AMPS parameter in the CALIBRATION menu, first to its maximum setting (100%), and then to its minimum setting (33%), (Note that the values are 100% Amps, 33% Amps, of new ratings with changed burden). Finally return it to the desired value for your motor.
      4. Save the new desired 2)RATED ARM AMPS parameter with another PARAMETER SAVE.

####CHANGE PARAMETERS/FIELD CONTROL/FIELD ENABLE

  • PIN99 to ‘DISABLE’
    • Using Permanent Magnet DC machine, so field needs to be disabled

####CHANGE PARAMETERS/CALIBRATION

  • PIN2 to ‘9.6’ (/RATED ARMATURE AMPS)
  • PIN3 to ‘100.00’ (/CURRENT LIMIT (%))
  • PIN4 to ‘2.00’ (/RATED FIELD AMPS) - N/A - field is disabled
  • PIN5 to ‘1800’ (/BASE RATED RPM)
  • PIN6 to ‘1800’ (/DESIRED MAX RPM rpm)
  • PIN7 to ‘0.00’ (/ZERO SPEED OFFSET)
  • PIN8 to ‘60.00’ (/MAX TACHO VOLTS)
  • PIN9 to ‘ARMATURE VOLTS (AVF)’ (/SPEED FBK TYPE)
  • (/ENCODER SCALING)
    • PIN10 to ‘DISABLED’ (/QUADRATURE ENABLE)
    • PIN11 to ‘1000’ (/ENCODER LINES)
    • PIN12 to ‘1.0000’ (/MOT/ENC SPD RATIO)
    • PIN13 to ‘NON-INVERT’ (/ENCODER SIGN)
  • PIN14 to ‘4.32’ (/IR COMPENSATION)
  • PIN15 to ‘1.0000’ (/FIELD CUR FB TRIM)
  • PIN16 to ‘1.0000’ (/ARM VOLTS TRIM)
  • PIN17 to ‘1.0000’ (/ANALOG TACHO TRIM)
  • PIN18 to ‘185.1’ (/RATED ARM VOLTS)
  • PIN19 to ‘208.0’ (/EL1/2/3 RATED AC )
  • PIN20 to ‘1’ (/MOTOR 1,2 SELECT)

####CHANGE PARAMETERS/CURRENT CONTROL

  • PIN93 to ‘10.00’ (/CUR PROP GAIN)
  • PIN94 to ‘1.00’ (/CUR INT GAIN)
  • PIN95 to ‘56.50’ (/CUR DISCONTINUITY)

####DISPLAY FUNCTIONS/REDUCED MENU ENABLE

  • REDUCED MENU to ‘ENABLE’

####DISPLAY FUNCTIONS/PASSWORD CONTROL/ALTER PASSWORD

  • ALTER PASSWORD to ‘0432’

####PARMETER SAVE

Storing the altered values in the drive so that they are retained when the control supply is removed. This is achieved by travelling to the PARAMETER SAVE location in the main menu. Press the right key to enter the PARAMETER SAVE window. Once there, using the UP key saves all the presently prevailing parameter values. The bottom line of the display will read SAVING and then FINISHED. If you wish to abandon changes made since the last save, simply remove the control supply WITHOUT having performed parameter save.
