normally written after occurrence of the arming) : No braking resistor is connected (SIZE B model supported) 197 Technical Manual for EA190 Series Servo Driver V100 The P-OT terminal is active, and the command is forward Check the position of the forward limit switch 1: Release the forward limit switch 2:
Give a reverse command Run beyond the forward limit position Check the current position of motor and value of P1-26 Correct the command and the P1-26 set value Set P1-26 to the maximum value, and turn off its function The absolute value system runs forward to exceed the allowed number of revolutions and the command is in the forward direction Check whether a proper value is set for P8-05 Adjust the value set for P8-05 Give a reverse 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 - noT - :
Reverse overrun warning 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 A l E09 : Warning for excessive times of writing a parameter to EEPROM via communication (the parameter can be 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 section 9.5.3 for details. A l E0A :
Request for power-on again Warning reason Inspection Handling method The parameter of power-on again is changed - When the parameter setting is completed, power on the device again Warning reason Inspection Handling method No braking resistor is connected 1: Check whether the short-circuit piece of the built-in braking resistor is connected (P+ and D) 2: When an external braking resistor is used, check whether lines are well connected 3: Test the braking resistor in the power failure status After the lines are connected, power on the device again Replace the braking resistor A l E0b :
Internal data exchange between chips is abnormal Warning reason Inspection Handling method Internal data exchange between chips is abnormal Check whether the alarm is cleared after power-on again Send it to the distributor or manufacturer for repair
