695.11.3 Absolute EncoderSetup (with ropes)Initial Start UpThe following will outline the procedure for aligning an absolute encoder foruse with a permanent magnet motor and the following encoders: HIPERFACE,ENDAT, SIN/COS. The motor must be mounted in place and be electricallyconnected to the elevator controller. The motor encoder must also beconnected to the drive. In this case the ropes are already on the motor.At a certain point in the process, it will be necessary to put balancedload into the car to carry out this adjustment.If at any point during the set up process, if the drive should give theerror E.ENCC, the display will change automatically to 2.LF.26 anddisplay the error code from the encoder. Refer to parameter LF.26 forfurther information.Initial Steps1) Verify the motor is correctly connected to the drive, i.e. phase U->U,V->V, W->W. With PM motors you can not have an arbitrary phasing.If direction reversal is required, the system direction can be reversed inLF.28 after the pole position is learned.2) Verify the correct mode of operation. LF.4 should be set to either PCLSdor P9LSS. If this is not the case see parameter US.10 to change theconfi guration mode.3) If not already done, enter the motor nameplate data and machine data inparameters LF.10 to LF.25. Learn the motor with the auto tune function,see sections 5.6.2 and 5.6.3.4) Verify the correct encoder feedback card is installed in the drive. Seeparameter 0.LF.26. Enter the encoder ppr in parameter LF.27. Make sureLF.28 = 0 and the sample time, LF.29 = 4 (4mSec.).Balancing the carThe following steps are necessary if the car is not at floor level and theweights can not be loaded into the car. Therefore it is necessary to drivethe car to a floor.1) Adjust parameter 0.LF.36 equal to LF.17.2) Set the inspection speed to a relatively low value 10-15ft/min.3) Adjust parameter LF.77 to 16,000.4) Try to run the car on inspection up or down. Note: the motor will make aloud noise and the control of the motor will be poor.5) If the car fails to move go back to step 3 and change the value to 32,000,48,000, or 64,000. Try to move the car again after each value.6) Once you fi nd a value which gives some movement you may need to addor subtract 8,000 to increase the torque output of the motor (i.e. you canmove a little but the motor does not seem to have enough torque).7) At this point if there is a long distance to cover in the hoist way, theinspection speed can be raised to a higher value.Balance the car such that when the brake opens, the car does not move at all.It might be necessary to let the car drift until it reaches an equilibrium.i
