| Alarm Code | Meaning | Fix within Mrzjw3-setup151e | | :--- | :--- | :--- | | | Overvoltage | Check Pn-500 (Regen resistor setting). Increase deceleration time (Pn-305). | | E-120 | Undervoltage | Monitor input voltage via I/O Monitor tab. Increase main power capacity. | | E-140 | Overload | Go to Monitor > Peak Torque . Reduce Pn-402 (Torque Limit) or lower acceleration. | | E-208 | Encoder error | Reboot the drive. If persistent, replace encoder cable. | | E-400 | Serial communication timeout | Go to Connection > Advanced > Set Retry Interval to 500ms. |
