Freqrol Mitsubishi AC Drives Frequency Inverter- AC Drives D-700 series

Flextech Industrial Supplies stocks Mitsubishi FR-D740 models (the three-phase 415 VAC variant used on Malaysian TNB three-phase supply) in common frame sizes from 0.75 kW through 7.5 kW, with same-day Klang Valley dispatch on in-stock units. The FR-D700 is the highest-volume Mitsubishi FREQROL in Malaysian distributor stock – the default FREQROL specified by Malaysian system integrators for conveyor drives, pump speed control, and machine auxiliary motor applications.

FR-D700 Technical Specifications

Model Number Structure: FR-D740

The FR-D700 model number encodes key specifications. Example: FR-D740-036-EC:

• FR-D: FREQROL D-series
• 740: three-phase 400V input, 0.75 kW (036 = 3.6 A rated output current)
• EC: CE marking (European conformity) – standard for Malaysian export machines

Key Technical Features

Advanced magnetic flux vector control: FR-D700’s sensorless speed control provides automatic torque boost at low speed – adjusting output voltage dynamically based on estimated motor flux state. This achieves faster torque response than fixed V/f control on conveyor and machine tool applications without encoder wiring.

Built-in PID controller: FR-D700 includes a single-loop PID function using analog 0-10 V or 4-20 mA feedback from a process transmitter. PID output controls inverter frequency directly – closed-loop pressure, flow, or level control without external PID controller or PLC PID block. Malaysian water treatment pump stations and HVAC fan control applications use this function to eliminate a separate process controller.

Electronic thermal relay: Pr.9 (motor rated current) sets the motor thermal overload protection threshold – the inverter trips on sustained overcurrent above the motor’s thermal limit, providing motor protection equivalent to a bimetallic overload relay without external OL relay hardware.

Modbus RTU communication: RS-485 Modbus RTU allows a PLC Modbus master to: write speed setpoint (output frequency) to holding register, issue Run/Stop commands, read output current, output frequency, fault code, and drive status. All operations use standard Modbus function codes 03 (read) and 06 (write single) – universal across Mitsubishi, Siemens, Panasonic, Delta, and Xinje PLC Modbus master implementations.

FR-D700 vs FR-E700/E800: When to Specify FR-D700

The FR-D700 is the correct FREQROL when all four conditions are met:

1. Motor power is at or below 15 kW
2. Open-loop sensorless vector control is adequate – speed regulation of ±5% under load variation acceptable
3. Communication requirement is Modbus RTU only – no CC-Link or CC-Link IE TSN required
4. No safety function (STO) required – standard emergency stop via main power or hardware contact adequate

Specify FR-E800 instead when: STO safety stop without full power disconnection is required, or motor power exceeds 15 kW at E800 range (up to 30 kW), or CC-Link IE TSN network integration with Mitsubishi iQ-F PLC is specified.

Wiring and Installation: Malaysian Panel Practice

FR-D740 three-phase input terminals (R/S/T) connect directly to Malaysian TNB 415 VAC three-phase supply via circuit breaker and optional line reactor. Output terminals (U/V/W) connect to motor with cable rated to inverter output current. Control terminals (SD, STF/STR, RH/RM/RL, AU, 2, 5, FM) provide dry contact run/stop, multi-speed reference, and 0-10 V analog reference inputs.

Mandatory Malaysian installation precaution: FR-D740 operates at 50 Hz base frequency (Pr.3 = 50 Hz) for Malaysian motors designed for 50 Hz TNB supply. Factory default Pr.3 = 60 Hz (Japan standard) – changing Pr.3 to 50 Hz is the first parameter modification required on Malaysian FR-D740 installations.

Mitsubishi FR-D700 FAQ

What is the power range of the Mitsubishi FR-D700?

FR-D740 (three-phase 400V): 0.4-15 kW. FR-D720S (single-phase 200V): 0.1-2.2 kW. Malaysian three-phase 415V applications use FR-D740.

Does FR-D700 support Modbus RTU?

Yes. Built-in RS-485 Modbus RTU. Pr.117 = station address (1-247). Pr.118 = baud rate. Compatible with Mitsubishi, Siemens, Panasonic, Delta, Xinje PLC Modbus masters.

What motor control modes does FR-D700 support?

V/f control, advanced magnetic flux vector (sensorless, ±5% speed regulation), general-purpose flux vector. No closed-loop vector (encoder) – specify FR-A800 for encoder feedback.

What is the first parameter to set on a new FR-D700 in Malaysia?

Pr.3 (base frequency): change from factory default 60 Hz to 50 Hz for Malaysian TNB-supplied motors. All Malaysian motor ratings are at 50 Hz.

What FR-D700 models does Flextech stock in Malaysia?

FR-D740-036-EC (0.75 kW) through FR-D740-750-EC (15 kW) – common frame sizes for same-day Klang Valley dispatch. Contact Flextech for specific model availability.
