Overview

The LS Electric L7NH is an EtherCAT servo drive series from 100 W to 3.5 kW (220 V) and up to 15 kW (400 V) with CiA 402 drive profile, supporting cyclic synchronous position, velocity and torque modes with distributed clocks. The L7NHA004U is the 400 W 220 V drive with 1 kHz speed bandwidth, 19-bit serial absolute encoder support, built-in STO and dynamic brake, and auto-tuning, notch filters and vibration suppression configured in Drive CM software. It pairs with LS APM-SE/XML servo motors and is used in multi-axis packaging, electronics assembly and printing machines controlled by LS XGB/XGI positioning modules or any EtherCAT master.

Frequently asked questions

Which motors work with the L7NHA004U?

LS APM-SE and XML 400 W motors with 19-bit absolute or incremental encoders; we quote the drive with motor, cables and brake option as a set.

Can I use it with a non-LS EtherCAT master?

Yes. The drive follows CiA 402 and is supplied with an ESI file; it works with Beckhoff, Omron, Delta and CODESYS-based masters.

Is the L7NH available from stock, and what is the lead time?

100 W–1 kW drives and motors are usually stocked in Vietnam; delivery typically 1–7 days. We confirm with the quotation.
