Overview
The 1S servo drive is designed to be commissioned fast on Sysmac controllers: EtherCAT synchronization down to 125 µs, automatic tuning, and a single cable to the motor carrying power, encoder and brake. The R88D-1SN04H-ECT is the 400 W, 200 V model, typically paired with R88M-1M40030T motors. Built-in Safe Torque Off at SIL3 removes an external safety relay in many machines, and the battery-free 23-bit absolute encoder simplifies maintenance.
Key features
- 400 W, 200–240 V AC single- or three-phase input
- EtherCAT (CoE, CiA402) with 125 µs cycle synchronization
- Safe Torque Off SIL3 / PL e built in
- One-cable connection: power, 23-bit absolute encoder and brake
- Auto-tuning and vibration suppression in Sysmac Studio
Typical applications
- Pick-and-place
- Packaging machines
- Electronics assembly
- Indexing tables

Frequently asked questions
Is the R88D-1SN04H-ECT available from stock, and what is the lead time?
Availability of the 1S Series Servo Drive 400 W EtherCAT changes with manufacturer production and distributor stock, so we confirm it per request rather than publishing a number that may be out of date. Send the part number and quantity through the quote form and you will receive stock position and lead time within one business day.
Is the R88D-1SN04H-ECT genuine, and what documentation comes with it?
We supply only genuine Omron products sourced from the manufacturer or authorized distribution channels. Each delivery includes the commercial invoice and packing list; a Certificate of Conformance, declaration of conformity and country-of-origin statement are provided on request, and the manufacturer's warranty applies.
Can you ship the R88D-1SN04H-ECT outside Vietnam?
Yes. We quote EXW Hai Phong, FCA/FOB, CIF or DAP and prepare the export documentation. Buyers in Japan, ASEAN, Europe and North America regularly consolidate multi-brand orders with us into one shipment.
What if the R88D-1SN04H-ECT is the wrong variant for my application?
Tell us the application in the notes field. Our engineers check the ordering code against your supply voltage, I/O, communication and environmental requirements and propose the correct variant or a successor part before quoting — at no charge.
