Lenze SMV

The Lenze SMVector (SMV) is a discontinued series of frequency inverters (variable frequency drives) that provided dynamic speed and torque control for a variety of industrial motor applications. It was formerly marketed under the joint "Lenze-AC Tech" brand.

Product features and specifications

1. High Performance Control: The SMV series featured sophisticated sensorless vector control with auto-tuning, which provided high starting torque and fast dynamic response. This allowed it to handle demanding applications with quick acceleration and recovery from shock loads.
2. Flexible Enclosure Options: It was available in NEMA 1 (IP31) for indoor use and NEMA 4X (IP65) for environments with atmospheric moisture or water jets. The robust design included a plastic enclosure and black anodized heatsink for corrosion resistance.
3. Intuitive Programming: The drive was known for its simple six-button programming interface and LED display. Many configurations could be quickly saved and transferred using a removable Electronic Programming Module (EPM).
4. Enhanced Connectivity: An EPM slot allowed for optional plug-in communication modules, providing connectivity to industrial networks like Modbus/RS485, CANopen, and Profibus.
5. Broad Power Range: It was available with multiple voltage and power options to suit various motor sizes:
6. Voltage: 120V, 240V, 480V, and 600V options were available, with single- or three-phase .
7. Power: Covered a wide power range, from 0.25 kW up to 45 kW on certain models.
8. Integrated Functions: The drives included built-in functions such as:
9. A PID controller with an energy-saving "sleep mode".
10. Dynamic braking that only required an external resistor.
11. Multi-speed presets and a sequencer.
12. Motor overload and short-circuit protection.

Typical applications

1. Food processing machinery
2. Conveyor systems
3. Packaging equipment
4. Pumps and fans
5. HVAC systems

Current product status and replacements

The Lenze SMVector series is a superseded product line and is no longer being manufactured.

1. Migration Path: Lenze recommends that customers migrate from SMV drives to newer models, such as the i510 protec and i550 protec series, which offer improved performance and features.
2. Aftermarket Support: Third-party suppliers also offer replacements and service support for the discontinued SMV line.
