Product details
Product Overview
ESV112N04TXB is a Lenze SMVector frequency inverter from the NEMA 1 (IP31) series. It runs a 1.1 kW motor on 3/PE 400/480 V mains. The drive uses sensorless vector control for stable torque at low speed. It ships without an integrated EMC filter as the standard X-coded variant. This unit suits panel builders and machine OEMs who need a compact, proven AC drive with flexible network options.
Key Advantages
- Sensorless vector control with auto-tuning for smooth startup and strong low-speed torque.
- 500 Hz output frequency supports high-speed spindles and special motors.
- Modular option slot lets you add Modbus, CANopen, DeviceNet, PROFIBUS DP or EtherNet/IP later.
- 175 % overload for short bursts of heavy load.
- Compact NEMA 1 housing for indoor cabinets and wall mounting.

Installation Guide
- Mount the drive vertically on a flat indoor surface. Keep clearance above and below for airflow.
- Confirm mains voltage matches 3/PE 400/480 V before wiring.
- Connect motor cables to U, V and W terminals. Keep cable length short to reduce noise.
- Use shielded cable for analog signals and network cards to limit interference.
- Ground the drive and motor properly for safety and EMC performance.
- Follow local electrical codes and lockout procedures during installation.
Commissioning and Maintenance
- Run the auto-tuning routine to match the drive to the motor.
- Set motor nameplate data before the first start.
- Check fan and heatsink airflow every few months.
- Inspect terminals for loose screws during routine service.
- Clean dust from the heatsink with dry compressed air.
- Review fault logs after any trip event to find the root cause.

Expert Review
The SMVector line has a long field record in pumps, fans and conveyors. This 1.1 kW unit keeps the same proven control platform in a small NEMA 1 housing. The option slot is the standout feature. You can start with basic I/O and add Modbus or EtherNet/IP when your machine network grows. Just remember this variant has no built-in EMC filter. Plan an external filter if you need strict emissions compliance. For legacy replacements, keep the v16 parameter map handy. That saves time on commissioning.
Manager’s Insight
Buyers often ask for a drive that is easy to stock and easy to adapt. ESV112N04TXB fits that need. One base unit covers many small motor tasks, and the plug-in network cards handle different plant protocols. Stock the RS-485/Modbus card alongside it for the most common retrofit jobs. This keeps lead times short and avoids extra part numbers. The 12-month warranty and 12 to 24-hour dispatch also help service teams meet urgent repair windows.
Best Fit Applications and Equipment
- Small conveyors and material handling lines
- Pumps and fans in building services
- Packaging machines with variable speed needs
- Textile and wire drawing equipment
- Doors, gates and simple positioning tasks
- Retrofit projects replacing older AC Tech drives
Buying Guide
- Match the drive to your motor power. This model suits 1.1 kW motors.
- Check mains voltage. This unit runs on 3/PE 400/480 V.
- Decide on network needs early. Pick the option card before you order.
- Confirm enclosure needs. NEMA 1 is for indoor, protected spaces.
- Add an external EMC filter if your site has strict emission limits.
- Keep spare option cards on hand to speed up future upgrades.
FAQ
Q: Does this drive include a network card?
A: No. The base unit has an empty option slot. Add an ESVZ-series card for Modbus, CANopen, DeviceNet, PROFIBUS or EtherNet/IP.
Q: Can I run a 1.5 HP motor with this model?
A: The rated motor power is 1.1 kW (1.5 HP) at 400/480 V. Check motor current against the 3.5 A output rating before you commit.
Q: Is an EMC filter built in?
A: No. This is the standard X-coded variant without an integrated filter. Use an external filter when local rules demand low emissions.
Q: What is the highest output frequency?
A: The drive reaches 500 Hz. That covers most standard motors and some high-speed spindle duties.
Q: How fast do you ship?
A: Orders leave our warehouse within 12 to 24 hours. FedEx, UPS and DHL handle delivery.
Q: What happens if the drive fails?
A: The 12-month warranty covers manufacturing defects. Contact our team with the model and fault code for fast help.
Q: Can I get help choosing the right option card?
A: Yes. Tell us your PLC or network type. We will match the card to your control system.
Q: Is this model still supported by Lenze?
A: SMVector is a legacy line. Lenze still offers v16.0 operating instructions. The suggested migration path is i500/i550 protec.
