ECMA-C10604SS Delta ASDA-A2 Series AC Servo Motor

Product Overview

The ECMA-C10604SS (ECMA-C10604SS) is a high-performance AC Servo Motor from Delta Electronics' prestigious ASDA-A2 series. Specifically designed for high-precision applications, this 400 W motor combines a compact 60 mm frame with a high-resolution 20-bit incremental encoder, capable of delivering 1,280,000 pulses per revolution. This model is a "Full-Option" variant, factory-equipped with both an electromagnetic brake and an oil seal, making it ideal for vertical axis control (Z-axis) in CNC machinery, high-speed pick-and-place robots, and automated packaging lines where preventing axis drop during power loss is critical.

Technical Configuration & Model Logic

The Delta ECMA-C10604SS follows a specific nomenclature optimized for industrial motion control. The "C" rating denotes a 220 V supply requirement with a high nominal speed of 3000 r/min, providing the agility needed for rapid industrial cycles. The "SS" suffix indicates a specialized shaft configuration that includes a keyway (with screw hole) and high-grade mechanical protection. The integrated oil seal prevents the ingress of lubricants and cutting fluids into the motor housing, while the 20-bit encoder ensures ultra-smooth low-speed performance and superior rejection of external disturbances, placing it at the forefront of B2B motion solutions.

Technical FAQs

Why is the 20-bit encoder significant for this 400 W motor?

The 20-bit resolution provides extreme precision for positioning tasks. It allows the ECMA-C10604SS to eliminate "cogging" and torque ripples at low speeds, ensuring that delicate operations—such as lens grinding or micro-assembly—maintain a high-quality finish and consistent accuracy.

What is the role of the "S" configuration (Brake and Oil Seal)?

The electromagnetic brake is essential for vertical applications to hold the load in place when power is removed. The oil seal allows the motor to be coupled directly to gearboxes or used in environments with splashing fluids, protecting the internal windings and encoder from contamination.

Can this motor be used with the ASDA-B2 series drives?

While physical connections may match, the ECMA-C10604SS is optimized for the ASDA-A2 series drive to take full advantage of the 20-bit encoder and high-speed communication features. Compatibility with B2 series may be limited by the drive's maximum encoder frequency.

Engineering & Installation Guide

• Brake Power Sequence: Always ensure the 24 VDC brake power is synchronized with the servo drive's "Servo Ready" signal. Releasing the brake before the motor develops holding torque can lead to unintended axis movement.

• Oil Seal Maintenance: During installation, apply a light coat of lubricant to the oil seal lip. Ensure the shaft is free of burrs to prevent tearing the seal, which is critical for maintaining the IP65/IP67 rating in fluid-heavy environments.

• Mounting Torque: Use the 60 mm frame's standard mounting holes. Ensure the coupling is correctly aligned; even a 0.1 mm misalignment can lead to premature bearing failure or encoder errors due to high-frequency vibration at 3000 r/min.

Engineering Advantages

The ECMA-C10604SS stands out for its superior power-to-weight ratio, packing 400 W of power into a 2 kg frame. Delta’s motor winding technology minimizes heat generation, allowing for high-duty cycle operations without thermal derating. The "SS" shaft design, featuring a keyway and screw hole, provides a standardized and secure mechanical interface that resists slippage during high-torque acceleration and deceleration phases. This motor is a robust, "set-and-forget" component designed for the rigors of 24/7 industrial manufacturing.
