motor speed 1000rpm higher than the speed limit over 20ms

Trouble shooting procedure
Check the angle of motor whether in right position; Check the supervisory interface of operation panel U6【check the angle whether the angle is in the range 252±5】【Too big angle will cause over current and over speed when motor accelerate and sudden stop】
Check motor: Test motor plug between foot 4 and 1 ,2,or 3 by (Ω channel) of multimeter to see whether it is in short circuit.; And check the 3 phases of motor U【2】、V【2】、W【1】whether they are have same resistance.
