EA180 Series Servo Drive Users Manual Chapter 8 Warning, Alarm and Troubleshooting 8.1 Alarm diagnosis and troubleshooting When the servo drive has an alarm, the fault display Al. " will appear on the LED display, and the electric machine will coast to stop or stop at zero speed (according to the setting of P0-08, but zero speed stop is only for second-level alarm). The drive records the last 4 alarms, which can be viewed through group d1. The alarm and troubleshooting are as follows: 99 Al001: Short circuit : Hardware overcurrent :
Software overcurrent Al002 Al00C Alarm Scenarios Inspection Troubleshooting Motor wiring error Check the phase sequence of the wiring between the motor and the drive Re-wiring according to instructions Control parameters setting exception Check if the set value is much greater than the factory value Restore to the default value and fix it step by step. The commands have changed dramatically. Check if the control input command changes too drastically Correct the change rate of the input commands or enable the filtering function Drive output short circuit 1: Check the wiring status of the motor and the drive or whether there is short circuit in the wire. 2:
Check whether the motor is damaged 1: Eliminate short circuit and prevent metal parts from being exposed. 2: Replace the damaged motor External braking resistance is too small or short-circuited Check whether external braking resistor conforms to specifications Use braking resistors that conform to the instructions and set the P8-10, P8-11 and P8-13 parameters correctly. Drive hardware failure The alarm still occur when all of that above faults have been eliminated Send it to distributor or manufacturer for overhaul. Al003 :
AD initialization alarm Alarm Scenarios Inspection Troubleshooting Drive hardware failure Check if this fault repeats after power cut and restart Send it to distributor or manufacturer for overhaul. Al004 : Memory exception alarm Alarm Scenarios Inspection Troubleshooting Parameter data write exception Check if this fault repeats after power cut and restart Replace the drive Store too frequently Check whether the host device program frequently writes to the EEPROM of the drive. Correct the upper device program, please use RAM address for parameters that need to be written frequently. The P7 group can be used to adjust the address pointing. Al005 :
System parameters exception Alarm Scenarios Inspection Troubleshooting Parameters set have conflict Check the parameters set before the alarm Fixed parameter errors Al006 : AD sampling alarm Alarm Scenarios Inspection Troubleshooting Excessive external analog sample deviation or conversion timeout Check if this alarm repeats after power cut and restart Send it to distributor or manufacturer for overhaul.
