Write Disable Error

Mitsubishi Electric · FR-D700 Basic Inverter

What does Write disable error mean?

Parameter setting was attempted while parameter writing is set to be disabled, or an overlapping range has been configured for frequency jump parameters (Pr. 31 to Pr. 36), or normal communication between the PU and inverter is compromised. This prevents parameter changes, hindering proper configuration or commissioning.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Check the physical connection between the PU and the inverter to ensure stable communication.
