Initial Start Up
i
3) If the controller is providing the speed command via analog or serial
command, set the inspection speed value in the controller to zero. If the
drive is providing the command there is no need to change the inspection
speed in the drive.
Learn Process
1) Set LF.3 = S Lrn. This will start the learn process.
2) The display will change to StArt.
3) Press and hold inspection up. The motor contactor should pull in and the
brake should not pick. Motor current will begin to ow, an audible noise
in the motor will be heard, and the drive display will change to LS103 .
4) The drive will measure various parameters in the motor as well as in the
drive’s own power stage. During each measurement the display will
change to signify what is being measured. In the event of problems during
the measurement phase the factory can use the codes to determine what
is happening.
5) Continue holding the inspection switch ON until the drive displays done.
8) Release the inspection switch, the drive will nish by making several
calculations, CALC, and updating the parameters values with the
measured values.
AUTO TUNE COMPLETE!
FAIL: the measurement sequence was interrupted, i.e. the inspection
switch was released prematurely, electrically the motor was not properly
connected, or the controller dropped the enabled signal to the drive.
Verify if the controller is dropping the signal by rst setting LF.3 to conf
and try again. If the controller still drops the enable and the motor
contactor, the problem lies in the controller.
FAILE: Drive fault occured during learn process. See last drive fault
0.LF.98 and diagnose.
FAILd : the drive is not able to begin measurements due to a con guration
error. Consult the factory to resolve.
E.cdd: the measurement of one of the motor parameters was not
possible. Repeat the process and note what code is displayed just before
the error occurs. Then contact the manufacture for assistance. In some
cases the error can be avoided by preadjusting some motor data.
Remember to put the drive back into run mode in LF.3 and return the
controller adjustments to the previous values!
