Chapter 10 Warning, alarm and handling 10.1 Alarm diagnosis and handling measures When the servo driver becomes subject to an alarm, the digital manipulator will display AI for alarm ”;the motor will automatically brake or brake at zero speed (according to setting of P0-08; zero-speed braking only applies to a second-level alarm). The driver will record information on the latest four alarms, which can be viewed via group d1. Alarm display and its handling measures are provided below: 190 Technical Manual for EA190 Series Servo Driver V100 RL001 : Short circuit : Hardware over-current :
Software over-current RL002 RL00C Reason for alarm Inspection Handling method Motor wiring error Check the wiring phase between the motor and the driver Reconnect the wire according to the instructions Control parameter setting abnormal Check whether the setting is far greater than the default value Restore the default value and make corrections step by step Command changes too sharp Check if the control input command changes too wildly Correct the input command change rate or enable the filtering function Driver output short circuit 1: Check the wiring status between the motor and the driver or check the conductor against short circuit 2: Check if the motor is damaged 1:
Rule out short circuit, and prevent exposure of the metal conductor 2: Replace the damaged motor The external braking resistor has too small resistance or is short-circuited Check if the external braking resistor conforms to the specification Use a braking resistor conforming to the instructions, and properly set parameters P8-10, P8-11 and P8-13 Driver hardware failure Alarm still remains after all problems above are eliminated Send it to the distributor or manufacturer for repair RL003 :
AD initialization alarm Reason for alarm Inspection Handling method Driver hardware failure Cut off the power and restart; check whether the fault still remains Send it to the distributor or manufacturer for repair RL004 : Storage abnormality alarm Reason for alarm Inspection Handling method Abnormal write of parameter data Cut off the power and restart; check whether the alarm still occurs Replace the driver Highly frequent storage Check the upper computer program to see whether frequent write operations are performed to the EEPROM of the driver Correct the upper computer program, and use the RAM address for parameters requiring frequent write operations.
The address direction can be adjusted through group P7. RL005 : System parameter abnormal Reason for alarm Inspection Handling method Parameters set have conflicts Check parameters set before the alarm Correct wrong parameters RL006 : AD sampling alarm Reason for alarm Inspection Handling method When the external AD sampling deviation is too great or conversion times out Cut off the power and restart; check whether the alarm still occurs Send it to the distributor or manufacturer for repair RL007 : Encoder abnormality 1 Reason for alarm Inspection Handling method Encoder released Check the CN5 and encoder connector of the Reinstallation
