Yaskawa Servo Driver SRDA-SDA71A01A-E
原价为：$480.00。$400.00当前价格为：$400.00。
The Yaskawa SRDA series is an important branch of the Yaskawa Σ-II (Sigma II) servo system. It is a high‑performance servo drive specifically designed for linear motors and direct‑drive (DD) motors (including direct‑drive rotary motors).
⚙️ Core Positioning and Features
Dedicated Drive: The SRDA series is not intended for standard AC servo motors (such as SGMGH/SGMSH). Instead, it is specifically paired with Yaskawa linear motors (e.g., SGLGW/SGLFW series) and DD torque motors (e.g., SGMCS series) for applications requiring ultra‑high precision and direct load driving.
High‑Performance Control: Inherits the high response of the Σ‑II series (speed frequency response up to 1.6 kHz). Supports high‑resolution serial encoders (up to 24‑bit, 16,777,216 pulses per revolution), enabling extremely smooth low‑speed operation and micron‑level positioning.
Full Closed‑Loop Control: Built‑in full closed‑loop control capability allows direct connection to external linear scales or encoders, eliminating mechanical transmission errors and achieving true full‑closed‑loop position control.
Rich Interfaces: Standard support for MECHATROLINK‑II (Yaskawa’s high‑speed motion bus), as well as analog voltage and pulse train commands, making it compatible with a wide range of host controllers.
📝 Model Number Breakdown (using SRDA‑200A as an example)
The ordering code for the SRDA series generally follows this pattern:
| Model Component | Example (SRDA‑200A) | Explanation |
|---|---|---|
| Series Prefix | SRDA | Fixed prefix indicating a dedicated servo drive for linear/DD motors. |
| Rated Current | 200 | Represents the maximum output current of the drive. Common ratings include 100 (100A), 200 (200A), 400 (400A), etc. Higher values indicate higher drive power. |
| Suffix (Version/Power) | A | Usually denotes the design version or power supply specification (e.g., single‑phase/three‑phase 200V class). Some models may carry additional suffixes such as ‑S (indicating safety function). |
Complete model example: SRDA‑200A means a drive with a maximum output current of 200A, designed for 200V class power supply and intended for linear/DD motors.
