Parameter Description
panel will flicker and display “TUN”. If the measurement fails, the operation panel will flicker
“FAL” for three seconds and then return to normal display.
• For executing the system inertia auto-tuning function, set P.301 to 4 in the mode of closed
loop vector control and set the inertia self-learning torque P.631 and P.632 respectively,
then press the forward rotation or the reverse rotation key. The measuring result will be
different due to the different setting of self-learning torque. The principle of setting
self-learning torque is that the difference between self-learning torque P.631 and P.632
can’t be too small and the measuring torque can’t be set too big, or the acceleration time
will be too short that the measuring result will have a large error.
