Detailed Function Description
49
0: No action: Forbidding autotuning.
1: Rotation autotuning:
z Do not connect any load to the motor when performing autotuning and ensure
the motor is in static status.
z Input the nameplate parameters of motor (P2.01~P2.05) correctly before
performing autotuning. Otherwise the parameters detected by autotuning will be
incorrect; it may influence the performance of inverter.
z Set the proper acceleration and deceleration time (P0.11 and P0.12) according
to the motor inertia before performing autotuning. Otherwise it may cause
over-current and over-voltage fault during autotuning.
z The operation process is as follow:
a. Set P0.17 to be 1 then press the DATA/ENT, LED will display “-TUN-” and
flickers. During “-TUN-” is flickering, press the PRG/ESC to exit autotuning.
b. Press the RUN to start the autotuning. LED will display “TUN-0”.
c. After a few seconds the motor will start to run. LED will display “TUN-1” and
“RUN/TUNE” light will flicker.
d. After a few minutes, LED will display “-END-”. That means the autotuning is
finished and return to the stop status.
e. During the autotuning, press the STOP/RST will stop the autotuning.
Notice: Only keypad can control the autotuning. P0.17 will restore to 0
automatically when the autotuning is finished or cancelled.
2: Static autotuning:
z If it is difficult to disconnect the load, static autotuning is recommended.
z The operation process is the same as rotation autotuning except step c.
Notice: The Mutual inductance and current without load will not be detected by
static autotuning, if needed user should input suitable value according to
experience.
