What Is the FR-PA07?
The FR-PA07 is Mitsubishi Electric’s current-generation parameter unit for the FREQROL FR-A800 and FR-F800 series inverter drives, providing a dedicated operator interface with a backlit LCD display showing inverter status, output frequency, output current, output voltage, fault history, and parameter values in plain text — eliminating the need to decode numeric parameter codes displayed on the inverter’s basic built-in LED display. The unit connects to the inverter’s PU (Parameter Unit) connector via a standard RJ45 cable, enabling operation at distances of up to 20 metres from the inverter — valuable for commissioning, fault diagnosis, and parameter adjustment on inverters mounted in high or enclosed positions where direct access to the inverter’s front panel is impractical. The FR-PA07 supports all parameter functions of the FR-A800 and FR-F800 series: reading and writing individual parameters, copying parameter sets between inverters (using the FR-PA07’s built-in parameter storage), comparing parameter sets between the FR-PA07 memory and a connected inverter, and monitoring real-time operating values (output frequency, current, voltage, power, motor thermal state, alarm history) in the FR-PA07’s LCD display during inverter operation. The unit includes a rotary frequency dial for manual frequency setting and dedicated RUN, STOP, and RESET keys for direct inverter control from the parameter unit.

Typical Industrial Applications
The FR-PA07 is deployed wherever FREQROL FR-A800 or FR-F800 inverters require convenient remote operation and parameter access beyond the basic capability of the inverter’s built-in LED display. In water treatment pump stations where FR-A800 pump inverters are installed in floor-standing IP54 enclosures at 2-metre height, the FR-PA07 enables the maintenance technician to adjust pump speed, read energy consumption data, and access fault history from a convenient handheld position rather than standing on a step ladder to reach the inverter’s front panel. HVAC fan control systems in commercial buildings use the FR-F800 series inverters for variable speed air handling, and the FR-PA07 enables building maintenance engineers to commission fan speeds and check motor thermal state without specialist laptop software. Industrial conveyor systems with multiple FR-A800 inverters at different positions along the conveyor use the FR-PA07 as a portable commissioning tool — one FR-PA07 unit serves the entire conveyor by connecting to each inverter in sequence for parameter verification and speed adjustment. In machine tool spindle drive applications using FR-A800 series inverters for spindle speed control, the FR-PA07 provides the commissioning engineer with access to the motor tuning parameters (offline auto-tuning, V/F pattern settings, slip compensation) that are not accessible from the machine’s CNC interface. Mining and heavy industrial conveyor systems using FR-A800 high-capacity inverters rely on the FR-PA07 for fault diagnosis in remote or elevated inverter installations where direct panel access is impractical during plant operation.
Expert Tips
When using the FR-PA07 for parameter copy between inverters of the same model, verify that the source and destination inverters have identical firmware versions before initiating the parameter copy — parameter set compatibility between firmware versions is not always guaranteed, and copying parameters from a newer firmware inverter to an older firmware inverter may result in unrecognised parameters that are silently ignored, causing subtle performance differences between the copied and original configuration. After parameter copy, perform a parameter comparison (FR-PA07’s compare function) between the FR-PA07 stored set and the destination inverter to confirm all parameters were written correctly. For commissioning engineers using the FR-PA07 as a portable tool across multiple FR-A800 inverters, label each stored parameter set in the FR-PA07’s memory with the inverter’s location and date — the FR-PA07 can store multiple parameter sets in its internal memory, and unlabelled sets become indistinguishable after a few weeks of multi-site commissioning work. When using the FR-PA07 at maximum cable distance (20 metres), use a shielded Cat5e or Cat6 patch cable for the RJ45 extension rather than an unshielded flat telephone-type cable — in industrial environments with significant electrical noise, an unshielded RJ45 cable at 20 metres may cause intermittent communication errors between the FR-PA07 and the inverter that manifest as display freezing or parameter write failures. Connect the cable shield to earth at the inverter end to prevent common-mode noise coupling into the PU communication signal.
Frequently Asked Questions
Q: Is the FR-PA07 compatible with older FREQROL inverter series such as the FR-A700 or FR-E700?
A: The FR-PA07 is designed primarily for the FR-A800 and FR-F800 series. Compatibility with older series (FR-A700, FR-E700, FR-D700) depends on the PU connector communication protocol — some older inverter models use a compatible PU communication protocol that allows the FR-PA07 to connect and display basic parameters, but full parameter name display and all FR-PA07 functions may not be available on older series. Verify compatibility with the specific older inverter model against Mitsubishi’s FR-PA07 compatibility list before relying on the FR-PA07 for older inverter commissioning.
Q: Can the FR-PA07 be permanently panel-mounted for continuous inverter monitoring, or is it only a handheld commissioning tool?
A: The FR-PA07 can be permanently panel-mounted using the optional mounting frame accessory — the unit’s flat rear surface and mounting clip design allow it to be installed in a panel cutout for permanent display of inverter operating data. In permanent mounting applications, the FR-PA07 provides continuous display of output frequency, current, and drive status without requiring a separate HMI — a cost-effective monitoring solution for simple inverter applications where a full PLC-HMI system is not justified.
Q: Does the FR-PA07 require any parameter settings on the FR-A800 inverter to enable PU communication?
A: Yes. The FR-A800 parameter Pr.79 (Operation mode selection) must be set to a value that enables PU operation (typically Pr.79 = 0 for PU/external combined mode or Pr.79 = 1 for PU mode only). If the inverter is configured for external terminal or network-only control (Pr.79 = 2 or higher values disabling PU), the FR-PA07 can still read parameter values and monitoring data but cannot issue RUN/STOP commands or change frequency setpoints via the parameter unit — the inverter will display a «PS» (PU stop) indication when PU run commands are attempted in external-only mode.
