0: NO operation, i.e. forbidding autotune.
1: Parameters autotune
Prior to parameters autotune, the motor must be disconnected with its load
ensuring the
motor at no-load condition, and confirming the motor is at static state.
Prior to parameters autotune, it is a must to correctly input the motor nameplate
parameters (P2.01
P2.05), otherwise what is self learned about motor parameters may be
not correct.
Prior to parameters autotune, the Acceleration and Deceleration time (P0.11 and P0.12)
should be set properly based on the motor inertia, otherwise over current fault may happen
during motor parameters autotune.
When the autotune of motor parameters is started by setting P0.17 as 1 and then pushing
the button DATA/ENT , LED displays “-TUN-” and flickering, then push the button RUN to
begin the procedure of the motor parameters autotune. At this time, “TUN-0”is displayed. After
the motor is started, “TUN-1”is shown and “RUN/TUNE” light is flickering. When the autotune
of parameters is finished, “-END-”is displayed, and finally back to the stop state interface.
When “-TUN-”is blinking, the process of parameters autotune can exit by pushing the button
PRG/ESC.
During the process of parameters autotune, it can be stopped by pressing the button
STOP/RST . Please note, the start and stop of the parameters autotune can only be done
through keypad. Once the parameter autotune is finished, this function code automatically
restores to 0.
