ESMD552C4TXA Lenze SMD Frequency Inverter for 5.5 kW Motors

The ESMD552C4TXA is a compact Lenze SMD frequency inverter. It runs a 5.5 kW four-pole asynchronous motor on 3/PE 400/480 V mains. This C4TXA variant includes CANopen communication. It uses V/f control with auto-boost and slip compensation. It has no built-in EMC filter. The unit suits simple speed control in industrial automation. It is a previous-generation AC Tech product. Lenze still offers official SMD operating instructions. Powergear X supplies this model with a 12-month warranty and 12-24 hour dispatch.

Installation Guide

Mount the drive vertically inside an IP20 cabinet.
Keep clearance for airflow above and below the 146 x 114 x 171 mm frame.
Use shielded low-capacitance motor cable up to 50 m.
Use unshielded motor cable up to 100 m when shielding is not required.
Wire 3/PE 400/480 V mains within 320 to 528 V.
Connect the relay output for AC 250 V / 3 A or DC 24 V / 2 A loads.
Add an external EMC filter because this model has none built in.

Commissioning and Maintenance Convenience

Set V/f curve, auto-boost and slip compensation from the keypad.
Use three configurable digital inputs for start, stop and preset speeds.
Read motor speed from the 0…10 V analog output.
Use CANopen for fast parameter upload and remote control.
Check fan and heatsink every six months in dusty rooms.
Verify terminal torque after the first week of running.

Compatibility Notes

Works with 5.5 kW four-pole asynchronous motors in the 400/480 V class.
Fits 3/PE 400/480 V mains with 50/60 Hz supply.
Speaks CANopen natively and needs no extra fieldbus card.
No official successor is named by Lenze, so plan spares early.
Same frame as ESMD402C4TXA and ESMD552L4TXA for easy panel swaps.

Expert Review

The ESMD552C4TXA is a solid pick for simple pump, fan and conveyor drives. Its 150% overload for 60 s covers most start-up torque needs. CANopen is built in, so wiring stays clean. The missing EMC filter is the main trade-off. Budget for an external filter and cabinet space. The 2.0 kg frame is light and easy to fit. For a legacy SMD line, this unit keeps spare-part planning simple.

Manager’s Insight

This inverter sells well to plants that already run Lenze SMD drives. Buyers value the 5.5 kW rating and the built-in CANopen port. Stock two units per line. The SMD series is a previous-generation product. Lead times can stretch, so order before your current drive fails. Powergear X keeps stock and ships fast to cut downtime.

Best Fit Equipment and Applications

Pumps and fans with light variable torque loads
Conveyors and material handling lines
Packaging and labeling machines
Woodworking and textile machinery
Retrofit of older Lenze SMD panels
CANopen-based factory networks

FAQ

Does the ESMD552C4TXA include an EMC filter?
No. Add an external EMC filter for noisy mains.
Can it run a 5.5 kW motor at 480 V?
Yes. Output current is 11.0 A at 480 V with a 4/6/8 kHz carrier.
Which fieldbus does it support?
CANopen only. No extra fieldbus card fits this base unit.
What is the maximum motor cable length?
50 m shielded or 100 m unshielded.
How does temperature affect output?
Full current up to +40 °C, then derate 2.5% per °C to +55 °C.
Is there an official successor model?
No. Lenze lists SMD as a previous-generation series with no named replacement.
How fast do you ship?
Orders leave in 12-24 hours by FedEx, UPS or DHL.
What does the warranty cover?
12 months against manufacturing defects.
My old SMD drive failed after 12 years. Should I stock spares?
Yes. Legacy stock is limited, so keep one unit per critical line.
Can I reuse the same panel cutout?
Yes. The frame matches ESMD402C4TXA and ESMD552L4TXA.
