Product Description

The Omron R88D-1SN01H-ECT is a 1S series servo drive with built-in EtherCAT communication, designed for industrial automation systems requiring precise and responsive motion control. This 100W servo drive delivers reliable performance for a wide range of applications, from packaging machines to robotics and CNC equipment.

Operating on single-phase or three-phase AC200/240V power (170/252V, 50/60Hz), the Omron R88D-1SN01H-ECT provides a rated output current of 0.8 Arms and a maximum output current of 3.1 Arms, supporting up to 350% momentary maximum torque for fast dynamic response. The EtherCAT communication interface enables a minimum cycle time of 125μs, ensuring synchronized control across multiple axes.

The drive features a 23-bit absolute encoder system that eliminates the need for battery backup, reducing maintenance costs and space requirements. It includes a built-in relay for direct motor brake control, simplifying external wiring and system design. The control loop design minimizes overshoot by 40% and reduces settling time by 30% compared to standard drives, improving overall machine productivity.

Safety is a top priority with the Omron R88D-1SN01H-ECT. It incorporates Safe Torque Off (STO) functionality with two implementation options: hardwired STO meeting Cat3 PLe (EN ISO 13849-1) and SIL3 (IEC 61508) standards, and network STO (FSoE) compliant with Cat.3 PLd and SIL2 certifications. These safety features help protect operators and equipment while minimizing downtime.

With an IP20 protection rating, the drive is designed for cabinet installation (recommended IP54 enclosure) and operates reliably in temperatures from 0 to 55°C with humidity up to 90% RH (non-condensing). The unit measures 223mm (height) × 40mm (width) × 196.05mm (depth) and weighs 1.2kg, making it suitable for space-constrained installations.

Application scenarios

The Omron R88D-1SN01H-ECT, a 100W EtherCAT servo drive, is widely used in 3C product assembly lines. It helps reduce the positioning error of placement machines from ±0.05mm to ±0.01mm and increases the production line speed by 30%, raising the output from 120 pieces per hour to 156 pieces per hour. This 1S series servo drive also cuts energy consumption by 18% and can run continuously for one month without failures, making it a reliable choice for high-precision assembly tasks. As a high-performance Omron R88D-1SN01H-ECT servo drive, it greatly improves the efficiency and stability of 3C assembly lines.

In packaging machinery, the Omron R88D-1SN01H-ECT plays an important role in multi-variety production. It shortens the machine changeover time by 60%, reducing the original 90-minute changeover time to less than 36 minutes. This 100W EtherCAT servo drive allows operators to switch product formats quickly through pre-programmed settings, reducing manual adjustment errors by 33% and increasing the equipment operating rate to 99.4%. The Omron R88D-1SN01H-ECT is especially suitable for food, pharmaceutical, and cosmetic packaging lines that require frequent format changes.

The Omron R88D-1SN01H-ECT is also applied in SMT placement machines, especially for the Z-axis positioning of placement heads. When controlling a 200g load on the vertical axis, it reduces the picking offset from 0.1mm to within ±0.03mm at a 100Hz motion frequency. This precision motion control servo drive also reduces high-frequency noise, with only weak electromagnetic noise of -55dB in the 2.4 kHz frequency band, meeting the IEC 61000-6-4 standard. The Omron R88D-1SN01H-ECT's high synchronization accuracy makes it ideal for microsecond-level response scenarios like SMT production.

FAQ

Q: What is the Omron R88D-1SN01H-ECT and which series does it belong to?

A: The Omron R88D-1SN01H-ECT is a 100 W AC servo drive from Omron's 1S-series, designed with built-in EtherCAT communications for high-speed, high-precision motion control applications. It operates on a closed-loop feedback control mechanism using position, velocity, and current three-loop control to achieve accurate motion tracking and positioning. The 1S-series covers a broad power range from 50 W to 15 kW, making it suitable for everything from small 100 W applications to heavy-duty industrial machinery. The "H" in the model number indicates operation at 200–240 VAC supply voltage, distinguishing it from the "L"-variant which operates at 100–120 VAC.

Q: What are the key electrical specifications (rated output, voltage, current)?

A: The Omron R88D-1SN01H-ECT has a rated output of 0.1 kW (100 W). Its main power supply voltage range is 200–240 VAC single-phase (170–252 VAC operational range). The rated main circuit current is 0.8 A RMS input (1.8 A max surge), while the servo drive output current is rated at 1.8 A. The control circuit requires a separate 24 VDC power supply. The AC servo system supports both single-phase 200 VAC and three-phase 200 VAC configurations, offering flexibility for diverse machine designs. Minimum fuse rating recommendation: Use a Class gG (IEC 60269-1) fuse between the power supply and noise filter-consult the official 1S-series manual (I586) for exact amperage ratings per model.

Q: What are the physical dimensions and weight of the R88D-1SN01H-ECT?

A: The Omron R88D-1SN01H-ECT has unpacked dimensions of 223 mm (height) × 40 mm (width) × 196.05 mm (depth). Its unpacked weight is 1,200 g. The unit carries an IP20 ingress protection rating, meaning it is protected against solid objects larger than 12 mm but is not intended for direct exposure to water jets or submersion-installation inside an IP54 or higher control cabinet is required for most industrial indoor applications. The slim 40 mm width reduces DIN rail space consumption by approximately 33% compared to previous-generation Omron servo drives, enabling higher panel density in control cabinets.
