Xinje DS5K Series User Manual

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 P3-28 and the internal reverse torque limit of P3-29, 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 P3-28 and P3-29 (P3-38/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:

P0-74 is 0, the anti-stall alarm is not opened by default, and users can configure it according to
their own needs.
(4) Before firmware version U2-07 3760, the torque comparison value of anti-blocking alarm is
P3-28/P3-29; after firmware version U2-07 3760, the torque comparison value of anti-blocking alarm is
P3-38/P3-39.
(5) P3-38/P3-39 is only used as the comparison value of anti-blocking alarm (added after version
3760). P3-28/ P3-29 is the internal torque limit of the actual operation of the motor.

1. if this parameter value is less than external torque limit value, the final limit value is this parameter.
2. The unit is percent of the motor rated torque; the default value is 300%. The real max output torque
is limited by motor overload times.
