KEB COMBIVERT F5 Instruction Manual page 57

3) If the controller is providing the speed command via analog or serial
command, set the inspection speed value to zero 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 flow, 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 finish by making several
calculations, CALC, and updating the parameters values with the
measured values.
AUTO TUNE COMPLETE!
Errors: In the event the drive can not complete the measurements two
i
error messages may occur.
FAILd : the drive is not able to begin measurements due to a configuration
error. Consult the factory to resolve.
FAIL : the measurement sequence was interrupted, i.e. the inspection
switch was release prematurely, electrically the motor was not properly
connected, or the controller dropped the enabled signal to the drive.
Verify if the controller is droping the signal by first 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.
E.ccd: the measurement of one of the motor paramters was not possible.
Repeat the process and not what code is display 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!
Reconnect the brake wire!
