The ESMD371L4TXA frequency inverter provides efficient motor control for small machinery. Lenze designed this unit for single-phase power systems at 230 Volts AC. It delivers a rated power of 0.37 kilowatts, which equals approximately 0.5 horsepower. The drive handles a rated output current of 2.2 Amperes continuously.
Many light-duty applications benefit from this inverter. For example, small conveyors, fans, pumps, and positioning systems all work well with the ESMD371L4TXA. Its output frequency spans from 0 to 500 Hertz, giving you wide speed adjustment capabilities. Additionally, the drive supports two communication protocols: Modbus and LECOM. This flexibility makes integration with existing control systems straightforward.
This inverter accepts an electrical supply of 1 to 230V AC. The input phase configuration can be 1/N/PE AC or optionally 3/N/PE AC, providing installation flexibility.
Key electrical parameters include:
Rated power: 0.37 kilowatts (0.5 HP)
Rated output current: 2.2 Amperes
Supply voltage: 230 Volts AC, single-phase
Output frequency range: 0 to 500 Hertz
Input phase options: 1(3)/N/PE AC
The ESMD371L4TXA uses a single-axis motor output and follows a single-axis supply concept. This design simplifies wiring and reduces complexity. For communication, the drive supports Modbus and LECOM network protocols. Meanwhile, the degree of protection is IP20, which means the unit is safe for installation inside electrical cabinets.
Approvals for this model include CE, cULus, and C-Tick. These certifications confirm compliance with international safety and quality standards. Therefore, you can use the ESMD371L4TXA in many regions without additional compliance testing.
The ESMD371L4TXA features a NEMA housing, which provides better environmental protection than standard open frames. However, the IP20 rating still limits its use to dry indoor locations. The enclosure protects against solid objects larger than 12 millimeters but offers no water resistance.
Weight is approximately 1.2 kilograms or 2.6 pounds. Specific dimensions are compact, allowing easy mounting in tight control panels. Operating temperature typically ranges from 0 to 55 degrees Celsius. Storage temperature goes from -20 to 70 degrees Celsius.
First, mount the ESMD371L4TXA vertically inside a clean, dry control cabinet. Leave sufficient space around the unit for cooling airflow. Next, connect the single-phase 230V AC input power to the L and N terminals. If you use a three-phase supply, connect to the appropriate terminals as shown in the manual.
Then, wire the motor leads to the output terminals. The ESMD371L4TXA controls a single motor axis only. Connect control signals to the digital and analog inputs based on your application needs. After that, apply power and configure parameters using the keypad or software. Set motor data correctly before running. Finally, set up Modbus or LECOM communication if remote control is required.

Can the ESMD371L4TXA run on three-phase power?
Yes. The input phase specification is 1(3)/N/PE AC. This means you can use either single-phase or three-phase input. However, the supply voltage must always be 230V AC.
What is the difference between Modbus and LECOM?
Modbus is a standard industrial protocol used by many devices. LECOM is Lenze’s proprietary communication protocol. The ESMD371L4TXA supports both, so you can choose whichever fits your existing system.
Does this drive have an internal brake chopper?
No. The ESMD371L4TXA does not include an internal braking transistor. You need an external braking resistor if your application requires rapid deceleration.
Can I use the ESMD371L4TXA outdoors?
No. Its IP20 rating and NEMA housing are designed for indoor use only. Moisture and dust will damage the unit. Install it inside a weatherproof enclosure if outdoor use is unavoidable.
What happens if the output current exceeds 2.2 Amperes?
The drive will continue operating up to its current limit. However, prolonged overload may trigger a fault. For short periods, the ESMD371L4TXA can handle higher currents, but continuous operation should stay at or below 2.2 Amperes.
