51Initial Start UpDriving the car to a floorIf possible let the car coast up to a floor where the weights can be loaded into the carto balance it. If this is not possible then it is possible to drive the car down underpower. Note: the motor current will be high and therefore operation with thismode should be limited.1) Adjust LF.77 to 0 and try to run the car on inspeciton in the down direction.2) If the motor stalls or the car goes up instead of down change the value of LF.77 to15000 and try to run the motor again.3) If this does not work try values of 30000 and 45000 in LF.77.4) Drive the car down to the nearest floor where the weights can be loaded into thecar.Balancing the car1) put enough weight into the car such that when the brake is opened the car remainsstationary. If there is any movement whatsoever, add or subtract weight.Alignment Process1) Adjust LF.3 = conF2) Set LF.77 = 22063) Press and hold the inspection up switch. The brake should open and motor currentwill begin to flow in one phase and the current will ramp up to the motor’s ratedvalue. The motor sheave should turn slowly and then stop when the motor rotorhas lined up with one of the stator poles. The display should change from thevalue 2206 to a value which represents the actual encoder position in relation tothe motor pole. Once this value is stabilized, the alignment has been found.Continue holding the inspection switch as the drive will then try to move the motorclockwise and counter clockwise to verify the motor’s rotation is consistent withthe encoder’s.4) If the drive triggers the error E.ENC1 or a stabile value in LF.77 is not reached, thephasing between the motor and encoder is reversed, the motor’s rotation isbackwards from the encoder. Release the inspection switch. If LF.28 is 0 thenchange the value to 3. If LF.28 is 1 change the value to 2. Go back to step 1 and trythe adjustment process again.5) Once the this process is complete make note of the final position number fromLF.77 in the job information. This position number is valid only for this motor andencoder. If the encoder is physically removed from the motor, this process willneed to be done again.Return to Normal Operation1) Cycle the power to the drive off and then on allowing the display to go blank in-between.2) Set LF.76 to a value of 8 or 9.3) Raise the speed gain values in LF.31, LF.32 and LF33 back to their default values,3000,1000,2000 respectively.4) Put the drive into run mode by setting LF.3 to run.5) Run the motor on inspection up and down. The speed displayed in LF.89 shouldbe stable and should match the command speed value in LF.88. Additionally themotor current in LF.93 should be fairly stable and below the rated FLA of the motor.
