    Error code: H0LD (name: operation panel lock)

    Content: Set to operation lock mode. Operations other than the STOP/RESET button will not be possible. (For details, please refer to the Mitsubishi Inverter User Manual)

    Processing: Press the MODE button for 2 seconds and the operation lock will be released.

    Error code: L0Cd (name: password setting)

    Content: The password function is being set and the parameters cannot be displayed or set.

    Remedy: Enter the password in the pr.297 password registration/release, and then perform the operation after releasing the password function. (For details, please refer to the Mitsubishi Inverter User Manual)

    Error code: Er1 (name: write error is prohibited)

    Contents: When pr·77 parameter write selection is set to prohibit the writing, the parameter setting is attempted; when the frequency jump setting range is repeated; when the PU and the inverter cannot communicate normally.

    Remedy: Check the setting value of pr·77 parameter write selection; confirm the setting value of pr·31~pr·36 (frequency jump); confirm the connection between PU and inverter.

    Error code: Er2 (name: write error in runtime)

    Content: Write at the time of the pr.77≠2 (when it is written regardless of the operating state in any operation mode) or when the STF (STR) is ON. ,

    Check: Confirm the setting value of pr·77 and whether it is running

    Processing: set to pr·77=2 and set the parameters after stopping the operation.

    Embedded Printer

    Embedded printers are mainly used in some self-service terminals, such as ATM machines, queuing machines, self-service refueling machines, medical testing equipment, industrial weighing equipment, etc., modular design, highly integrated with the equipment, stronger integration! Embedded printers are divided into two types, one is panel type, the other is embedded type. Panel type is generally used for equipment operated by fixed staff, and embedded type is generally used for unattended self-service terminals. equipment. Embedded printers are divided into two specifications: 58MM and 80MM, of which 58MM has products with and without automatic paper cutting function. Support OEM and ODM customization!
