Running The Motor; Absolute Encoder Setup (No Ropes) - KEB COMBIVERT F5 Instruction Manual

Initial Start Up

5.11.1 Absolute Encoder
Setup (no ropes)
HIPERFACE, ENDAT,
SIN/COS Encoders

The following will outline the procedure for aligning an absolute encoder
to the pole of a permanent magnet motor and the following encoders:
Hiperface, Endat, SIN/COS. The motor must be mounted in place and
be electrically connected to the elevator controller. The motor encoder
must also be connected to the controller. The motor must be able to
spin freely either by mechanically releasing the brake or through normal
electrical release.

If at any point during the set up process, if the drive should give the
error E.ENCC, the display will change automatically to 2.LF.26 and
display the error code from the encoder. Refer to parameter LF.26
for further information.
Initial Steps
1) 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
in LF.28 after the pole position is learned.
2) Verify the correct mode of operation. LF.4 should be set to either PCLSd
or P9LSS. If this is not the case see parameter US.10 to change the
configuration mode.
3) If not already done, enter the motor nameplate data and machine
data in parameters 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. See
parameter 0.LF.26. Enter the encoder ppr in parameter LF.27. Make
sure the sample time (LF.2) is set to 4mSec.
Alignment Process
1) Set LF.3 = P Lrn. The display should confirm with StArt
2) Press and hold the inspection up switch. Motor current will begin to
flow in one phase and the current will ramp up to the motor's rated
value. The motor sheave should turn slowly and then stop when the
motor rotor has lined up with one of the motor poles. The display
should show the actual position value of the encoder. As the motor
moves this value will change. When the motor rotor has aligned with
a pole, the value will stabilize. At this point, the alignment has been
found.
Continue holding the inspection switch as the drive will then try to
move the motor clockwise and counter clockwise to verify the motor's
rotation is consistent with the encoder's. The motor should return to
nearly the same position.
