The MIKOM MV series inverter is a crucial device in the field of industrial automation, and its user manual elaborates on key aspects such as equipment operation, parameter settings, and troubleshooting. This article provides systematic guidance on four core modules: operation panel functions, parameter settings, external control, and fault handling, based on the content of the manual.

1. Operation Panel Function Analysis

The operation panel is the direct interface for users to interact with the inverter, designed with both functionality and ease of use in mind. The panel’s main components include an LED display, function keys, and status indicators. The LED display shows real-time operating parameters such as output frequency, current, and voltage, and indicates operational status (e.g., RUN/STOP) and fault codes (e.g., Er.XX) through symbols. The function keys are clearly arranged, including:

• MENU/ESC Key: Used to enter the parameter settings menu or exit the current operation interface.
• ENTER Key: Confirms parameter modifications or enters submenus.
• RUN/STOP Key: Controls the inverter’s start and stop; pressing and holding it initiates emergency stop.
• MK Key: A multifunctional key whose function is defined by parameter P50.03 (e.g., inching control, free stop).
• Increment/Decrement Keys (>, <): Adjust parameter values or switch display pages.
• Shift Key (>>): Selects operation bits during parameter modification or cycles through display interfaces.

By using these keys in combination, users can perform operations such as parameter browsing, modification, and device control. For example, pressing and holding the MENU key for 3 seconds enters the password verification interface, where entering the correct password grants access to protected parameters.

2. Parameter Settings and Security Protection

1. Restoring Factory Default Parameters
To restore the device to its initial state, you can select the restoration range through parameter P50.20:

• P50.20=0: Restores basic menu parameters (P00-P19 groups).
• P50.20=1: Restores advanced menu parameters (P20-P49 groups).
• P50.20=2: Restores user-defined menu parameters (P50-P99 groups).

Operation steps: Enter the menu → select P50.20 → press ENTER to confirm → use the increment/decrement keys to choose the restoration range → press ENTER again to execute.

2. Password Setting and Removal
To prevent accidental operations, a user password can be set via parameter P50.00:

• Setting the password: Enter P50.00 → input a 4-digit password → press ENTER to confirm → the password takes effect after 1 minute of inactivity.
• Password verification: The system prompts for password entry when modifying protected parameters.
• Password removal: Power cycle the device or enter the correct password and press ENTER to lift protection.

3. Parameter Access Restrictions
Three levels of protection can be set via parameter P50.02:

• P50.02=0: No protection; all parameters can be modified.
• P50.02=1: Partial parameters locked (e.g., P00 group basic parameters are accessible, P20 group advanced parameters are locked).
• P50.02=2: All parameters locked; modifications require a password.

Additionally, the thousand’s place of parameter P50.03 can lock operation panel keys (e.g., disabling RUN/STOP operations), further enhancing security.

3. External Control Function Implementation

1. External Terminal Forward/Reverse Control
Configure terminal functions via parameter P10 group:

• Forward control: Set P10.01=1 (DI1 terminal as forward command).
• Reverse control: Set P10.02=2 (DI2 terminal as reverse command).
• Combined logic: Set multi-terminal combined logic via P10.03-P10.06 (e.g., DI1+DI3 for forward inching).

Wiring example: Connect the forward button to the DI1 terminal and COM terminal, and the reverse button to the DI2 terminal and COM terminal.

2. External Potentiometer Frequency Adjustment
Implementation steps:

• Parameter settings: Enter the P12 group → set P12.01=1 (AI1 as frequency reference source) → P12.03=0 (0-10V corresponds to 0-50Hz).
• Hardware wiring: Connect an external potentiometer (10kΩ) to AI1 (terminal 10) and GND (terminal 11).
• Debugging tips: Rotate the potentiometer and observe if the frequency value displayed on the LED changes linearly. Adjust P12.04 (filter time) if fluctuations occur.

I. Introduction to Operation Panel Functions and Parameter Management

Operation Panel Functions

The operation panel of the KINGDA Electric A800 series inverter is the core component for user interaction with the device. As seen from the fault image, the panel is equipped with a red LED display, currently showing “EC.34 0.00”, indicating the device is in a fault state. The functions of the buttons and knobs on the panel are as follows:

• ESC (Exit): Exit the current menu or cancel the operation.
• PROG (Programming): Enter parameter programming mode.
• ENTER (Confirm): Confirm selection or enter the next level menu.
• Direction Keys (Up, Down, Left, Right): Navigate menus or adjust parameter values.
• STOP/RESET (Stop/Reset): Stop operation or reset faults.
• RUN (Run): Start the inverter.
• Knob: The central black knob is used to manually adjust parameters or scroll through menus.

These controls are intuitively designed for easy user operation. The user manual on page 24 (“Operation Panel and Status Parameters”) provides a detailed description.

Parameter Initialization Method

Parameter initialization is used to restore the inverter to factory settings, typically performed during first use or troubleshooting. The specific steps are as follows:

1. Press the PROG key to enter the main menu.
2. Use the direction keys to navigate to the “Parameter Initialization” option (see “Function Parameter Table” on page 28 of the manual).
3. Press ENTER to confirm; if a password is set, enter the password to unlock.
4. Select “Yes” and press ENTER to perform initialization; the device will automatically restart upon completion.

After initialization, all parameters are restored to default values, and the user needs to reconfigure them according to the application.

Password Setting and Removal

The password function protects parameters from unauthorized modification:

• Setting a Password:

1. Enter the “Programmable Management Parameter Array” (page 90 of the manual).
2. Find the password setting item (usually parameter P10.XX).
3. Enter a 4-digit password and press ENTER to save.

• Removing the Password:
• If the password is remembered, it can be cleared by entering the correct password in the same menu.
• If the password is forgotten, contact the manufacturer’s technical support and provide the serial number (e.g., “A800-250007G-AB00-250040G” on page 7 of the manual) to unlock.
• Alternatively, clear the password through parameter initialization, but this will reset all settings.

Parameter Access Restriction Setting

Parameter access restrictions further enhance security:

1. Enter the “Programmable Management Parameter Array” (page 90).
2. Find the “Parameter Lock” or “Access Level” option (e.g., P10.01).
3. Set to “Lock Mode”, with options for “Read-Only” or “Fully Locked”.
4. After saving the settings, unlocked users cannot modify parameters.

These features ensure the security and stability of the device parameters.

II. External Terminal Forward/Reverse Control and External Potentiometer Speed Regulation

External Terminal Forward/Reverse Control

Controlling the inverter’s forward and reverse operation through external switches requires wiring and parameter settings:

• Wiring:
• Two-Wire Control (page 101 of the manual, “Two-Wire Switch Control for Inverter Forward and Reverse”):
  • Terminal FWD (Forward) connected to one end of the switch.
  • Terminal REV (Reverse) connected to the other switch.
  • COM terminal is the common ground.
• Three-Wire Control (page 101, “Three-Wire Self-Resetting Switch Control”):
  • SB1 (Start), SB2 (Stop), SB3 (Forward/Reverse Switch) connected to switches respectively.
  • COM terminal is the common ground.
• Parameter Settings:
• P02.01 (Start/Stop Control Source) set to “External Terminal Control”.
• P02.02 (Direction Control Source) set to “Terminal FWD/REV” or “Three-Wire Control”.
• P05.00 (Input Terminal Function Selection) assign functions to FWD, REV, or SB1/SB2/SB3.

External Potentiometer Speed Regulation

Adjusting the output frequency through an external potentiometer to achieve motor speed regulation:

• Wiring (page 100 of the manual, “External Potentiometer Connection to Inverter”):
• One end of the potentiometer connected to +10V (power), the other end to GND (ground).
• The middle tap connected to VI (analog input).
• Parameter Settings:
• P00.06 (Main Frequency Reference Source) set to “VI Analog Input”.
• P03.00 (Analog Input Range) set to 0-10V, corresponding to 0 to maximum frequency (P00.03).
• Calibrate P03.01 (Minimum Input Voltage) and P03.02 (Maximum Input Voltage) to match the potentiometer.

After correct configuration, users can flexibly control the inverter through switches or the potentiometer.

III. Analysis of EC.34 Fault Code

Fault Phenomenon and Missing Manual Information

The inverter displays “EC.34 0.00” and cannot operate normally. Upon checking pages 92-121 of the user manual (“Fault Diagnosis and Solutions” to “Common EMC Interference Problem Rectification Suggestions”), no explanation for EC.34 is found. After consulting the manufacturer’s technical staff, the response was “need to contact the dealer to solve”, suggesting that EC.34 is not a standard fault code.

Speculation on Fault Meaning

Combining the feedback from technical staff and the fact that it is not mentioned in the manual, EC.34 may be a black-box operation code set by the dealer. The analysis is as follows:

• Clock Function Association: The A800 series may have a built-in operation time limit mechanism (parameters may be hidden in the “Management Parameter Array” on pages 49-90), such as setting a 3-month operation cycle.
• Artificial Shutdown: After the cycle ends, EC.34 is triggered, displaying a fault and shutting down, but the hardware is actually undamaged.
• Commercial Purpose: This design may be set by the dealer to recover outstanding payments, promote services, or force users to pay additional fees, which is a malicious commercial practice.

This practice exists in certain market environments but lacks transparency and may harm user rights.

Solution Methods

1. Contact the Dealer:

• Provide the serial number and purchase certificate, and request to lift the restriction.

1. Technical Unlocking:

• Try parameter initialization (see Part One), which may reset the time limit but will clear all settings.

1. Legal Rights Protection:

• If confirmed as malicious setting, keep evidence (manual, pictures, communication records) and complain to consumer protection agencies.

---

IV. Summary and Suggestions

The KINGDA Electric A800 series inverter has an intuitive operation panel, rich functions, supports parameter initialization, password protection, and external control, suitable for various industrial scenarios. However, the EC.34 fault reveals potential commercial traps. Users should:

• Familiarize with the Manual: Master parameter settings and operation methods.
• Backup Parameters: Prevent loss of configuration during initialization.
• Choose Suppliers: Prioritize cooperation with reputable dealers.
• Keep Certificates: Ensure after-sales rights.

When facing unclear faults like EC.34, prioritize negotiating with the dealer; if unsuccessful, seek technical support or legal channels. This case reminds users to be vigilant against technical black-box operations and calls for the industry to standardize commercial behavior to protect user interests.
