When a fault occurs, it will output a fault code through an indicator light or a communication interface. Operators can quickly locate the cause of the fault according to the fault code, greatly shortening the fault Investigation time. At the same time, the module's structural design is easy to disassemble and replace, and the maintenance process is simple and convenient, which effectively reduces equipment downtime and improves production efficiency.

IV. Common Faults and Solutions
(1) Overcurrent Fault
Fault phenomenon: The driver displays an overcurrent alarm, and the output is interrupted.
Possible causes: The motor load is too large, exceeding the rated output current of the driver; the motor winding is short-circuited or grounded; the internal current detection circuit of the driver is faulty.
Solutions: Check the motor load, reduce the load or replace with a higher-power driver; detect the insulation of the motor winding, repair short-circuit or grounding faults; if the internal fault of the driver is suspected, contact professional maintenance personnel for inspection or replacement.
(2) Overtemperature Fault
Fault phenomenon: The driver temperature is too high, triggering overtemperature protection and stopping work.
Possible causes: The working environment temperature exceeds the range of 0-55°C; the driver's heat dissipation channel is blocked, resulting in poor heat dissipation; the motor runs at full load for a long time, causing the driver to heat up seriously.
Solutions: Improve the ventilation conditions of the working environment to reduce the ambient temperature; clean up dust and other debris on the driver's heat dissipation channel to ensure good heat dissipation; appropriately reduce the motor load to avoid long-term full-load operation.
(3) Communication Fault
Fault phenomenon: The driver cannot communicate normally with the upper computer or PLC, and cannot obtain the operating status or send control commands.
Possible causes: The communication line connection is loose or in poor contact; the communication protocol settings are inconsistent; the communication interface is damaged.
Solutions: Check the communication line, re-plug and fix the connection; confirm that the communication protocol settings of the driver, upper computer, and PLC are consistent; if the communication interface is damaged, replace the interface or contact maintenance personnel for handling.
(4) Motor Not Running
Fault phenomenon: The driver is normally powered, but the motor does not run.
Possible causes: Incorrect or loose motor wiring; the control command is not sent correctly; the driver's control mode setting is incorrect.
Solutions: Check the motor wiring to ensure correct and firm connection; check the control command transmission path to ensure normal transmission of commands; check the driver's control mode settings and reset them according to actual needs.
