Motor lock-rotor protection
Motor speed is almost 0 when servo-motor lock-rotor occurs, but actual current is very high,
servo drive and servo motor may be damaged because of long time lock-rotor, therefore, servo
drive provides the motor lock-rotor protection to prevent the damage from excessive
temperature in the situation of motor lock-rotor.
