AT500 Inverter Operation Guide and Fault Handling Summary

---

I. AT500 Inverter Operation Panel Usage

1. Operation Panel Layout and Indicator Description:
   • Introduces the display, buttons (RUN, STOP/RES, MK, Λ, V, >>, etc.) on the operation panel and their functions.
   • Explains the meanings of various indicators (Run, Alm, Hz, A, V, %, rpm, F/R, etc.).
2. Menu and Parameter Settings:
   • Describes the three-level menu mode (function parameter group, function code, function code modification) and its operation method.
   • Elaborates on how to view and modify various inverter parameters through the operation panel.
3. Operation Mode Control:
   • Introduces starting the inverter via the RUN button and stopping it via the STOP/RES button.
   • Explains the jog operation function and its debugging applications.

II. Terminal Control and External Potentiometer Debugging Mode Setup

1. Terminal Control Setup:
   • Guides users to enter the F0 parameter group and set F0.02 to 1 to enable terminal control.
   • Demonstrates how to assign functions to each input terminal through the F2 parameter group and explains wiring requirements.
2. External Potentiometer Debugging Mode:
   • Teaches users to set F0.03 or F0.04 to AI3 (keyboard potentiometer) to adjust the output frequency by rotating the potentiometer knob.

III. Inverter Fault Code Classification and Troubleshooting Methods

1. Overcurrent Faults (Err02-Err04):
   • Lists possible causes (output circuit short circuit, too short acceleration/deceleration time, etc.).
   • Provides solutions (check output circuit, adjust acceleration/deceleration time, etc.).
2. Overvoltage Faults (Err05-Err07):
   • Analyzes fault causes (excessively high input voltage, external force during deceleration, etc.).
   • Offers remedies (adjust input voltage, eliminate external force during deceleration, etc.).
3. Undervoltage Fault (Err09):
   • Describes fault causes (instantaneous power failure, low input voltage, etc.).
   • Suggests solutions (check input power supply, adjust voltage range, etc.).
4. Overload Faults (Err10-Err11):
   • Indicates faults may be caused by excessive load, motor stall, etc.
   • Proposes reducing the load, checking the motor and mechanical conditions, etc.
5. Input/Output Phase Loss Faults (Err12-Err13):
   • Analyzes fault causes (input power phase loss, faulty output wires or motor, etc.).
   • Offers advice on checking power and motor, troubleshooting peripheral faults, etc.
6. Module Overheating Fault (Err14):
   • Explains fault causes (high ambient temperature, blocked air ducts, etc.).
   • Emphasizes the importance of reducing ambient temperature, cleaning air ducts, replacing fans, etc.
7. Communication Fault (Err16):
   • Mentions possible causes (incorrect communication parameter settings, faulty communication cables, etc.).
   • Suggests checking communication parameters, cables, and the host computer.
