Because it can only rotate in one direction, after a certain period of time, the number of revolving
cycles will always exceed the upper limit of absolute value encoder.

5.7 Auxiliary functions
5.7.1 Anti-blocking protection
Anti-blocking alarm: When the motor speed is lower than P0-75 (unit 1 rpm) and the duration reaches
the set value of P0-74 (unit ms), the current output torque U0-02 is greater than the internal positive
torque limit of P3-38 and the internal reverse torque limit of P3-39, it will show the alarm E-165
blocking overtime.

Note:
(1) When P0-74 or P0-75 is set to 0, this alarm will not be detected;
(2) If this alarm occurs during normal operation of servo, please confirm:
(a) Monitor U0-02 motor torque and check if P3-38 and P3-39 torque limits are set properly;
(b) Check the external mechanical structure and installation;
(3) P0-74 the default value of locked rotor alarm time is as follows:
