Elmo G-TUB30-480ERSS0 Servo drives

Elmo G-TUB30-480ERSS0 Servo drives

Elmo’s G-TUB series is an ultra-compact, high-power density intelligent servo drive. The G-TUB30-480ERSS0 is a specific model in the series, designed to directly drive high-power servo motors, making it ideal for demanding applications requiring significant space and weight savings.

Key Features and Description
Extremely High Power Density

This is its most prominent feature. Despite its compact size, this driver can continuously deliver up to 30A of current and a 480V DC bus voltage, enabling it to drive very large servo motors (up to tens of kilowatts).

Intelligent Drive

This is more than just a power amplifier; it also houses a powerful processor and Elmo’s advanced algorithms (such as Gold Twitter and Gold Tune).

Advanced Servo Control: Supports high-performance current, velocity, and position closed-loop control.

Auto-Tuning: Automatically identifies and optimizes servo loop parameters, simplifying the debugging process and achieving optimal dynamic performance.

Programmability: Supporting Elmo’s SimplIQ programming environment, users can program complex motion programs (such as point-to-point motion and electronic camming) within the driver, enabling distributed control and reducing the burden on the host controller.

Rich Communication Interfaces

Primary Communication Interface: Supports EtherCAT (ER), a high-speed industrial Ethernet protocol and the industry standard for high-precision synchronized motion control.

Auxiliary Interface: Equipped with RS-232/RS-485 interfaces for convenient configuration, commissioning, and monitoring.

Powerful Safety Functions

Complies with stringent industrial safety standards (such as SIL2/SIL3, PL e).

Built-in STO (Slow-Down) function, a critical safety feature, ensures that the drive’s power output can be safely shut off in an emergency, preventing unintended startup.

Wide Applicability

Input Voltage: Supports a wide DC bus voltage range (please refer to the datasheet for details; the “480” in the model number may refer to the maximum voltage), making it adaptable to various power supply environments.

Feedback Interface: Compatible with a variety of high-resolution feedback devices, including EnDat 2.2, BiSS-C, HIPERFACE DSL, analog sine/cosine encoders (SS), and resolvers (R). The “ERSS0” portion of the model number indicates the supported feedback type combinations.

Rugged Industrial Design

The metal housing effectively dissipates heat through conduction cooling, making it suitable for long-term, stable operation in harsh industrial environments.
