Operation Panel Functions

The KD600M series VFD’s operation panel is the central interface for user interaction, integrating intuitive buttons, LED indicators, and a 5-digit display for parameter settings, status monitoring, and motor control. Below are the key functionalities:

Buttons and Controls

The panel includes the following buttons:

  • PRG: Enters programming mode to access parameter menus.
  • ESC: Exits the current menu or cancels an operation.
  • OK: Confirms parameter settings or selections.
  • RUN: Starts motor operation.
  • STOP: Stops motor operation or resets faults.
  • QUICK: Quickly sets commonly used parameters.
  • JOG: Enters jog mode for testing or fine-tuning.
  • UP/DOWN: Adjusts parameter values or navigates menus.

For example, to adjust the frequency from 0.00Hz to 5.00Hz, users can press PRG to enter the parameter menu, use the UP/DOWN keys to select the target parameter (e.g., P1-04), input the new value, and press OK to confirm.

LED Indicators

The panel’s LED indicators provide real-time status feedback:

  • RUN: Green, on indicates running, off indicates stopped, flashing indicates sleep mode.
  • L/D/C: Red, off indicates panel control, on indicates terminal control, flashing indicates communication control.
  • FWD/REV: Red, off indicates forward, on indicates reverse, flashing indicates direction mismatch.
  • TUNE/TC: Red, on indicates torque control, flashing indicates tuning or a fault.

Display Screen

The 5-digit LED display shows frequency, current, voltage, fault codes, and other information. Hexadecimal values are prefixed with “H.” (e.g., P7-29 displays as “H.3f”). The display supports multi-level menu navigation (group → code → value), enabling quick access and modification of parameters.

Related Parameters

Key parameters related to operation panel functions include:

  • P7-00 (Jog Run Frequency): Range: 0.00Hz to maximum frequency; Factory default: 6.00Hz.
  • P7-01 (Jog Acceleration Time): Range: 0.0s to 3000.0s; Factory default: 10.0s.
  • P7-02 (Jog Deceleration Time): Range: 0.0s to 3000.0s; Factory default: 10.0s.
  • P7-28 (QUICK/JOG Key Function Selection): Options: 0 (forward jog), 1 (forward/reverse switch), 2 (reverse jog), 3 (panel/remote switch), 4 (panel frequency source switch); Factory default: 0.
  • P7-16 (Keyboard Knob Precision): Options: 0 (0.01Hz) to 10 (10Hz); Factory default: 2.

These features make the operation panel a powerful and flexible tool for various control needs.

Parameter Initialization

Parameter initialization is a critical step for restoring default settings or backing up user configurations. The KD600M series offers the following function codes:

P0-28 (Parameter Initialization)

  • Options:
    • 0: No operation
    • 1: Restore factory settings (excludes motor parameters, records, and P0-20)
    • 2: Clear records
    • 3: Back up user parameters
    • 4: Restore backed-up parameters
  • Factory Default: 0
  • Modifiable State: Running state (★)

To perform initialization, users should enter P0-28 while the device is stopped, set it to 1, and confirm. The VFD will revert to factory settings, preserving motor parameters and run records.

P0-29 (Parameter Upload/Download)

  • Options:
    • 0: No function
    • 1: Upload parameters
    • 2: Download parameters (excludes P4 and A1)
    • 3: Download parameters (includes P4 and A1)
    • 4: Download all parameters
    • 5-7: Download modified parameters
  • Factory Default: 0
  • Modifiable State: Stopped or running state (☆)

This function allows users to back up custom parameters or restore from a backup, suitable for multi-device configurations or fault recovery.

Password and Parameter Access Restrictions

To prevent unauthorized modifications, the KD600M series provides password protection and parameter access restrictions:

Password Protection

  • P7-49 (User Password):
    • Range: 0 to 65535
    • Factory Default: 0
  • PF.00 (Factory Password):
    • Range: 0 to 65535
    • Factory Default: ***** (hidden for security)

Users can enable password protection by setting P7-49. Fault codes like Err25 (EEPROM read/write failure) or Err1A (password entry limit exceeded) may indicate password-related issues, requiring EEPROM chip inspection or technical support.

Parameter Access Restrictions

  • B0-00 (Function Code Read-Only Selection):
    • 0: Invalid (no restriction)
    • 1: Read-only (parameters cannot be modified)
    • Factory Default: 0
  • Parameter Status:
    • ★: Not modifiable during operation (e.g., P0-03: motor control).
    • ○: Manufacturer-only modification.
    • ●: Read-only (e.g., PF group parameters).

These restrictions ensure the security of critical parameters, preventing accidental changes or unauthorized access.

External Terminal Forward/Reverse Control and Potentiometer Speed Adjustment

The KD600M series supports external terminal control for forward/reverse operation and potentiometer speed adjustment, ideal for automated systems.

Forward/Reverse Control

  • Digital Input Terminals (DI1-DI10):
    • DI1: Default forward (function code 1).
    • DI2: Default reverse (function code 2).
    • Supports PNP/NPN modes, switchable via DIP switches.
    • Up to 10 digital inputs with optional IO1/IO2 expansion cards.
  • P5-11 (Terminal Command Mode):
    • 0: Two-wire mode 1
    • 1: Two-wire mode 2
    • 2: Three-wire mode 1
    • 3: Three-wire mode 2
    • Factory Default: 0

Wiring Method:

  • Connect DI1 and DI2 to a PLC or switch, with the COM terminal as the common return.
  • Ensure secure connections to avoid short circuits or poor contact.

Potentiometer Speed Adjustment

  • Analog Input Terminals (AI1, AI2):
    • Supports 0-10V or 4-20mA input.
    • P5-15 (AI1 Minimum Input): Range: 0.00V to 10.00V; Corresponding setting: -100.0% to 100.0%.
    • P5-16 (AI1 Maximum Input): Range: 0.00V to 10.00V; Corresponding setting: -100.0% to 100.0%.
  • Wiring Method:
    • Use a 1-5kΩ potentiometer, connecting to AI1 and +10V-GND terminals (+10V provides up to 10mA power).
    • Recommended wiring length is less than 20 meters to minimize signal interference.

Setup Steps:

  1. Set P5-11 to 0 (two-wire mode 1) to enable terminal control.
  2. Configure P5-15 and P5-16 to define the potentiometer input range.
  3. Rotate the potentiometer and observe frequency changes on the display to ensure proper speed adjustment.
