  • 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”.

• 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.
