1. Even if the value set in the P1-10 is more than the highest speed of the servo motor, it will be limited to the
maximum speed of the servo motor.
2. Do not assign the motor rotation signal (TGON) and the brake signal (BK) to the same terminal. If assigned to
the same terminal, due to the vertical axis of the falling speed, will make the TGON signal ON, the brake may not
move.
