MR-JE Alarm Code List (for HG-KN43J-S100)
Two categories: AL.xx Fault Alarms (machine stop) and E□.x Warnings (no stop). AL alarms require power cycle or software reset; warnings normally clear automatically once root cause is removed.
- AL Fault Alarms (Commonly Used)
| Alarm Code | Alarm Name | Root Cause & Troubleshooting |
| AL.10 | Undervoltage | Low main circuit voltage; phase loss, poor contact of contactor, insufficient power supply capacity, loose wiring |
| AL.12 | RAM Memory Error | Internal drive hardware failure; power cycle first. Repeated alarm → replace drive |
| AL.14 | Control Circuit Error | Internal CPU / control board failure; replace drive if restart ineffective |
| AL.16 | Encoder Initial Communication Error 1 | Loose CN2 encoder cable / connector, EMI interference, encoder damage |
| AL.1E | Encoder Initial Communication Error 2 | Encoder handshake failure on power-up; check cable, shield grounding, motor encoder |
| AL.1F | Encoder Initial Communication Error 3 | Mismatched encoder version / model; HG-KN is dedicated for MR-JE, do not mix other motors |
| AL.20 | Encoder Communication Error 1 | Encoder wire break, poor contact or heavy EMI during operation |
| AL.21 | Encoder Communication Error 2 | Hardware failure of encoder |
| AL.25 | Absolute Position Lost | Dead encoder battery or disconnected battery wire; homing required after reset (frequent alarm for S100 absolute encoder) |
| AL.24 | Main Circuit Fault | Short circuit on U/V/W, motor earth leakage, failed power transistor |
| AL.30 | Regeneration Fault | Fast deceleration, large load inertia; insufficient built-in regenerative resistor, broken resistor, incorrect PA02 parameter |
| AL.31 | Overspeed | Actual speed exceeds limit; excessive electronic gear ratio, abnormal pulse command, encoder fault |
| AL.32 | Overcurrent | U/V/W short circuit, motor insulation breakdown, damaged drive IGBT |
| AL.33 | Overvoltage | DC bus voltage＞400V; voltage rise by regenerative energy during deceleration, excessive input voltage |
| AL.35 | Command Pulse Frequency Error | Pulse frequency out of drive limit, wrong pulse wiring mode (differential / open collector) |
| AL.36 | SSCNET Communication Error (JE-B) | Loose / sharply bent fiber optic cable, duplicated station number, bus interference |
| AL.37 | Parameter Error | Parameter out of range or conflicting parameter combination; restore factory settings for test |
| AL.39 | Sequence Program Error (Position Table) | Wrong position table instruction or conflicting parameters |
| AL.45 | Main Circuit Overheat | Poor drive heat dissipation, high ambient temperature, blocked cooling fan |
| AL.46 | Motor Overheat | Overload, continuous stall, brake not released, poor heat dissipation |
| AL.47 | Cooling Fan Fault | Fan stuck or damaged |
| AL.50 | Position Excessive Deviation | Large gap between command and actual position; mechanical jam, insufficient torque, low gain |
| AL.51 | Vibration Detected | Servo vibration / abnormal noise; excessive gain, mechanical resonance |
| AL.61 | Forced Stop Alarm | Emergency stop EMG circuit open (hardware E-stop, immediate shutdown) |
| AL.86 | Network Communication Error (JE-C CC-Link IE) | Faulty Ethernet cable, wrong IP, switch fault, bus disconnection |
- E Warnings (No Shutdown, Display E□.x)
| Warning Code | Warning Name | Description |
| E6.1 | Forced Stop Warning | EMG terminal open warning (not a hard fault; often masked in projects – short EMG on CN1/CN3 or mask by parameter) |
| E8.1 | Homing Incomplete | Absolute encoder without homing after power-up; operation allowed but origin reference lost |
| E9.1 | Battery Warning | Low encoder battery voltage. Replace battery promptly to avoid AL.25 |
| E0.1 | Software Positive Limit | LSP software limit triggered |
| E0.2 | Software Negative Limit | LSN software limit triggered |
- Reset Rules
- AL faults: Remove fault condition then power off & on to reset; some alarms can be cleared via MR Configurator2 software
- E warnings: Clear automatically after condition recovered, power cycle usually unnecessary
- AL.25: Home return must be executed after alarm clearing
- High-Failure Reminders for HG-KN43J-S100
AL.25, E9.1: Absolute encoder battery related – most frequent faults
AL.16/1E/1F/20/21: CN2 encoder cable. Separate power cable and encoder cable routing; single-end shield grounding
AL.46: 400W motor is prone to overheat under heavy load or continuous low-speed operation
