Problem:
Unable to complete SPI
procedure successfully
Unable to complete Encoder
Synchronization procedure
successfully
Diagnostics and Troubleshooting
Troubleshoot:
Ensure correct motor data and that a Motor Tune has been
completed.
During the procedure, if a 'Values are not consistent' is displayed,
then a learned value falls out of range of the average of previous
values and the process will not complete successfully, but can be
done again as necessary.
If the LE03 Swap Encoder Channels setting for whether A/B
Channels Swapped is incorrect, this may cause more variance
in the encoder/pole position samples.
High motor inductance (> 100mH) values may have more
variance in the encoder/pole position samples.
The drive should automatically determine the correct LE07
Rotor Position Mode based on the learned motor data. It may
be possible to try the other setting.
If "Error Calc. Motor Data" occurs, change LM27 from Ld <> Lq
to Ld = Lq. This may provide better results.
The motor must be able to run normally during this procedure.
Check for any mechanical issues preventing movement.
Ensure current is not excessive; if so, troubleshoot as necessary.
For PM motors, the LE03 Swap Encoder Channels setting for
the A/B phasing must be correct, which cannot be determined
from the SPI procedure. If the SPI procedure was used to learn
the encoder/pole position, change LE03 as needed and relearn
encoder/pole position with SPI again before doing the Encoder
Synchronization procedure.
For Induction motors, the motor must be able to run in open loop.
Adjust the LC32 Low Speed Torque Boost as necessary.
If unable to run the car in the down direction as described in the
procedure because it is at or near the bottom terminal limit, run
the car in the up direction instead. When prompted with whether
or not the elevator traveled in the down direction, answer No if it
did and Yes if it didn't.
