Features 1. The Ability to Maximize Drive Performance ■ Advanced Flux Vector Control Example of motor temperature/speed variation characteristics (SFJR 4P 3.7kW motor). (Repeated operations at 90% usage rate, on-line auto tuning selected) New levels in drive performance have been achieved thanks to the use of advanced flux vector control, an original technology developed by Mitsubishi. 320 The units feature a RISC processor which is used for on-line auto tuning, turning the motor quickly when starting.
Features ■ Smart Driver Uneven rotation at low speeds has been greatly improved by the use of a smart driver (a newly developed ASIC) which directly monitors and controls the main circuit's status. • Uneven rotation: less than half that of a conventional Mitsubishi inverter at 1 Hz Example of comparative data on uneven rotation (inverter operation frequency: 3Hz; SF-JR 4P 3.
Features 2. Achieves New Levels of User-friendliness ■ Simple Operation FR-DU04 control panel ● The simple FR-DU04 control panel is provided as standard on all models. An optional extension cable can be used with the control panel. Operational and alarm signals can also be shown with this unit. ● The FR-PU04 LCD parameter unit with long-life backlight display is available as an option. The unit features Mitsubishi's original direct input method which uses the ten-key pad.
Features 3. Environmentally Friendly ■ Soft-PWM Control In addition to the conventional low-noise mode, Mitsubishi has developed its own original Soft-PWM control method which suppresses the increase in acoustic noise and limits RFI noise to minimum levels similar to those of the Mitsubishi FR-Z Series inverter. Note: The default setting is Soft-PWM control ON. ■ Motor Noise Data Example (SF-JR 4P 3.

External Dimension Diagrams ■ Making the housing plate more compact Housing plate When the inverter is being used inside a housing plate, the heat generated inside the plate can be greatly reduced by projecting the inverter's heat radiating fin outside of the plate. This mounting method is recommended when trying to reduce the size of a completely sealed housing plate. Notes 1. When mounting, use mounting attachment FR-A5CN (sold separately) (for models 1.5K~55K). 2.

Protective Functions Except for the motor's electronic thermal relay, the following functions are provided for the protection of the inverter itself, but they may also function when the inverter breaks down. Function name Description When the inverter output current exceeds the rated current by more than approximately 200% during acceleration/deceleration or at constant speed, the protective circuit activates, halting inverter output.
Protective Functions ● Resetting Methods When a protective function is activated, it halts inverter output (the motor coasts to a halt). It is held in this state and will not restart unless it is reset. To reset the inverter, three methods are available: - shut off the power, then turn it on again; - switch the reset (RES) signal ON for at least 0.1 second, then OFF; - press the RESET key on the control panel or parameter unit.
Selecting Peripherals and Options Name (Model) Power facility capacity Functions & Applications, etc. Please select a power supply that is larger than the kVA values stated in the "Power facility capacity" column in the Ratings table (p.8). However, in the case where the value exceeds 1000kVA and the wiring length is 10m or less, install an FR-BEL DC reactor (or AC reactor) to balance the power supply.
List of Options Name Type 12-bit digital input FR-A5AX Application, specifications, etc. Digital output Outputs signals such as output frequency, output voltage, output current in analog form.
