Technical Manual for EA350 Analog Pulse Type Servo Driver V101 : Reverse overrun warning : Warning for excessive times of writing a parameter to EEPROM via communication (the parameter can be normally written after occurrence of the arming) 250 direction The servo system has insufficient stability Check the set control parameter and the load inertia Re-correct the control parameter or reevaluate the motor capacity Warning reason Inspection Handling method The N-OT terminal is active, and the command is in the reverse direction Check the status of the reverse limit switch Reverse limit switch 2:
Give a forward command Run beyond the reverse limit position Check the current position of motor and value of P1-28 1: Correct the command and the P1-28 set value 2: Set P1-28 to the maximum value, and turn off its function The absolute value system runs reversely to exceed the allowed number of revolutions and the command is in the reverse direction Check whether a proper value is set for P8-05 1: Adjust the value set for P8-05 2:
Give a forward command The servo system has insufficient stability Check the set control parameter and the load inertia Re-correct the control parameter or reevaluate the motor capacity Warning reason Inspection Handling method After power-on, the upper computer/PLC/touch screen parameter has been modified for too many times Check whether the parameter requiring real- time modification uses corresponding RAM address For real-time change of the parameter address to corresponding RAM address (without presence of EEPROM), see 10.5.3 for details.
