Execution of auto tuning
When performing PU operation, press
of the
operation panel.
For External operation, turn ON the start command
(STF signal or STR signal). Tuning starts. (Excitation
noise generates at this time.)
Since the RUN signal turns ON when tuning is
started, caution is required especially when a
sequence which releases a mechanical brake by the
RUN signal has been designed.
During offline auto tuning, the following I/O signals
are the only valid signals (in the initial setting.)
It takes approximately 9s to complete the tuning.
• To force tuning to end
Enter signal to terminal MRS or RES, or press
during the PU operation mode. In the External
operation mode, enter signal to terminal MRS or
RES, or turn OFF the starting switch (STR or STR
signal) to end the operation.
After tuning is completed, check [Pr.96] setting.
• Ended properly...............3 or 103 is displayed.
• Ended in error ................One of 8, 9, 91, 92, and 92 is
displayed.
When offline auto tuning ends, press
of the operation
panel during PU operation. For External operation, turn
OFF the start signal (STF signal or STR signal) once.
This operation resets the offline auto tuning and the PU's
monitor display returns to the normal indication.
(Without this operation, next operation cannot be started.)
When tuning ends in error, auto tuning is not performed
properly, so the frequency search gain is not set. Perform
inverter reset (
refer to page 57
), and re-do the tuning.
When using the motor corresponding to the following
specifications and conditions, reset [
Pr. 9 Electronic thermal
O/L relay
] as below after tuning is completed.
(a) When the rated power specifications of the
motor is 200/220V(400/440V) 60Hz, set 1.1
times rated motor current value in
Pr. 9
.
(b) When performing motor protection from
overheat using a PTC thermistor or motor with
temperature detector such as Klixon, set "0"
(motor overheat protection by the inverter is
invalid) in
Pr.9
.
The motor constants measured once in the offline auto
tuning are stored as parameters and their data are held
until the offline auto tuning is performed again.
Monitor is displayed on the operation panel and parameter
unit (FR-PU04, FR-PU07) during tuning as below.
