ABB ACS380 Inverter Complete Guide

Common fault codes and solutions (on-site experience summary)

Fault code description, common causes, and solutions

2210 overcurrent output short circuit, motor insulation damage, and short acceleration time. Check the insulation resistance of the motor cable; Extend acceleration time; Check if the machinery is stuck

2310 overvoltage deceleration time is too short, the braking resistor is not connected or the resistance value is too high, which prolongs the deceleration time; Check the wiring and resistance of the braking resistor; Install brake chopper (already built-in)

4210 Overheating environment with high temperature, fan failure, and clogged radiator. Clean the radiator; Confirm the rotation of the fan; Reduce the switching frequency or reduce the capacity for use

Check if the 5090 motor rotates freely due to excessive load and mechanical lock; Increase the delay time of stall protection

7110 brake resistor overload braking is too frequent, and the power of the resistor is insufficient to reduce the braking utilization rate; Replace with a higher power resistor; Extend deceleration time

7510 STO channel fault safety circuit wiring error, FSPS-21 communication loss. Check if the voltage of the two STO channels is consistent; View parameter 31.22; Check PROFIsafe connection

F504 fieldbus timeout communication cable breakage, PLC stop checking bus connector; Confirm the operation of the PLC program; Increase communication watchdog time
