• When resolver position tuning ends, press
on the operation panel during PU operation. For External operation, turn
OFF the start signal (STF signal or STR signal).
This operation resets the resolver position tuning, and the PU's monitor display returns to the normal indication. (Without
this operation, next operation cannot be started.)
NOTE
• The data measured once in the resolver position tuning is stored in
Pr.1105
, and is held until the resolver position
tuning is performed again. However, performing all parameter clear resets the tuning data.
• If the resolver position tuning has ended in error (see the table below), tuning data is not set. Perform an inverter reset and
restart tuning.
• When tuning is ended forcibly by pressing
or turning OFF the start signal (STF or STR) during tuning, the tuning
does not end properly. (The tuning data have not been set.)
Perform an inverter reset and restart tuning.
• When the protective function (E.EP) is activated during tuning, check the wiring of the motor and the resolver,
Pr.359
setting, and then perform tuning again.
• When the tuning ends properly, the counter value of the offset between the motor home magnetic pole position and the
resolver home position is written in
Pr.1105
.
