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.

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

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).
