Operation and Handling

1. Four core operating modes

table

Applicable scenarios for setting key parameters of operation mode control source

Operator Control Body Operator F0-04=0 (operator command), F0-06=1 (preset frequency) Single machine debugging, manual operation

Terminal control DI/AI terminal F0-04=1 (terminal command), F0-06=2 (AI1 given) External switch/potentiometer control

Multi speed control, multi speed terminal F0-06=4 (multi speed), FC-00~FC-15 set speed, fixed speed switching (such as pipeline)

485 communication control upper computer (PLC, etc.) F0-04=2 (communication command), F0-06=7 (communication given) centralized control, multi device linkage

2. Key operational procedures

Motor parameter self-tuning (recommended for vector control):

Set motor nameplate parameters (F4-01~F4-06: power, voltage, current, etc.);

Select self-tuning mode (F4-00=1 static/2 rotation);

Press the RUN button on the operator to start, and it will automatically adjust for up to 2 minutes to update parameters such as motor inductance and resistance.

Trip reset:

After the fault occurs, the frequency converter cuts off the output and displays a fault code;

After investigating the cause, press the STOP/RESET button or reset through the DI terminal (assigned the “fault reset” function);

If the trip still occurs, power off for 10 minutes (confirm that the bus voltage is<45V) before restarting.

Fault handling and maintenance

1. Common fault codes and countermeasures

table

Fault code, fault name, core cause, handling measures

Err04 acceleration overcurrent acceleration time is too short, motor short circuit, load sudden change 1. Increase acceleration time (F0-23); 2. Check the insulation of the motor; 3. Check the load

Err09 deceleration overvoltage, short deceleration time, no brake resistor connected. 1. Increase deceleration time (F0-24); 2. Configure braking resistors; 3. Activate overexcitation braking

Err14 motor overload load is too large, and the overload protection gain is improper. 1. Reduce the load; 2. Adjust F9-01 (overload protection gain); 3. Check the heat dissipation of the motor

Err27 communication fault wiring error, parameter mismatch 1. Check 485+/485- wiring; 2. Confirm that the baud rate/address is consistent; 3. Add a terminal resistor (120 Ω)

2. Maintenance and upkeep

Daily maintenance:

Inspection: Motor sound/vibration, fan operation, ambient temperature;

Cleaning: Remove dust and oil stains from the surface of the frequency converter and fan.

Regular check (recommended every 6 months):

Tighten the wiring terminals, check the smoothness of the air duct, and test the insulation of the main circuit (500V megohmmeter).

Replacement of lifespan components:

Cooling fan: 2-3 years (to be replaced in case of abnormal noise/stoppage);

Electrolytic capacitor: 4-5 years (to be replaced in case of leakage/bulging).
