Omron 3G3SV-BB007-E 0.75kW 220V VFD for Motor Speed Control

The Omron 3G3SV-BB007-E is a compact variable frequency drive from the 3G3SV series. It delivers 0.75kW output power with single-phase 200-240V AC input. Designed for simple speed control of three-phase induction motors, this drive is ideal for small machinery, conveyors, fans, and pumps. Its built-in PLC interface includes digital inputs and an analog input for speed reference.

Electrical Specifications

Input: 200-240V AC, single-phase, 50/60Hz ±5%. Input current: 8.0A. Output: 3-phase, 0-240V AC, 0-400Hz. Rated output current: 4.2A. Overload capacity: 150% for 60 seconds, 200% for 3 seconds. Carrier frequency: 2-15kHz (adjustable). Efficiency: >95% at rated load. Built-in EMC filter (Class B) and DC reactor reduce harmonics.

Control and I/O

Control method: Sine wave PWM. Frequency range: 0.1-400Hz. Speed regulation: ±0.5% of maximum speed (open loop V/f). Digital inputs: 5 optically isolated (24V DC) – forward run, reverse run, multi-speed select, external fault, and reset. Digital output: 1 relay (NO/NC, 250V AC, 1A) for drive ready/fault. Analog input: 0-10V or 4-20mA (selectable) for speed reference. Analog output: 0-10V (frequency or current monitor).

PLC Interface Capabilities

The drive can be controlled directly by a PLC using the digital run command and analog speed command from a PLC analog output module. Alternatively, multi-speed operation (up to 8 preset speeds) can be selected via three digital inputs from PLC output cards. The fault relay output can be wired to a PLC input for alarm monitoring. An optional RS-485 (Modbus RTU) communication board (3G3AX-PS01) is available for network control.

Protection Features

Overcurrent, overvoltage, undervoltage, overload (electronic thermal), short circuit, ground fault, phase loss, and overheat protection. Stall prevention during acceleration/deceleration. Auto-restart after momentary power failure (up to 5 attempts). The drive also includes a braking transistor (external braking resistor optional) for rapid deceleration.

Programming and Settings

Parameter setting via digital operator (LED display and 4 buttons). Over 200 parameters accessible. Simple menu with 23 frequently used parameters. The drive supports two parameter sets (motor A and B). Parameter copy function to external keypad (optional 3G3AX-OP01). Factory default settings for general purpose applications.

Mechanical and Environmental

Dimensions: 115 x 128 x 120 mm (WxHxD). Weight: 1.1 kg. Mounting: DIN rail or screw fixing. Operating temperature: -10°C to 50°C (derate above 40°C). Humidity: 20-90% non-condensing. Protection rating: IP20 (open chassis). Altitude up to 1000m without derating. Vibration: 5.9 m/s² (0.6G).

Applications

Typical for small conveyors, agitators, packaging machinery, textile machines, and food processing equipment. The 0.75kW size is suitable for motor frame sizes 71-80. The VFD can be panel mounted or installed inside a control cabinet with ventilation.

Compliance

CE marked, UL 508C listed (File E171486), cUL, and RoHS. The drive meets EN 61800-3 for EMC and EN 61800-5-1 for safety. It is also compliant with the low voltage directive 2014/35/EU.

Conclusion

The Omron 3G3SV-BB007-E provides a cost-effective, reliable VFD solution for 0.75kW motors with straightforward PLC integration. Its compact size and analog control interface simplify retrofitting into existing automation systems.
