AC Servo Slide Table
The LESYH is a high precision variation of the LESH high rigidity slide table. This actuator improves positioning repeatability to ±0.01 and increases vertical work load dramatically compared to the LESH. The external motor can be mounted inline with the table, or in parallel to the left or right.
LESYH, Electric Slide Table, High Precision Type, AC Servo
The LESYH AC Servo Slide Table is a high-precision electric actuator designed to provide superior positioning accuracy and high-rigidity performance. An evolution of the LESH series, this model significantly improves positioning repeatability to ±0.01 mm and offers a substantially increased vertical work load capacity (up to 20 kg). It features an integrated AC servo motor — available with incremental or absolute encoders — and supports multiple mounting configurations, including inline or parallel motor positions. This series is ideal for industrial automation tasks requiring high speeds and forceful pushing capabilities.
LESYH, Electric Slide Table, High Precision Type, Motorless
The LESYH Motorless Slide Table provides the same high-precision mechanical benefits as its servo-equipped counterpart — including ±0.01 mm repeatability and high rigidity — but offers the flexibility of a motorless design. This version is engineered with shaft couplings and mounting patterns compatible with AC servo motors from over 18 different manufacturers, including industry leaders like Rockwell Automation, FANUC, Siemens, and Mitsubishi. It is available in body sizes 16 and 25 with strokes up to 150 mm, allowing engineers to integrate the slide table into existing control systems using their preferred motor brand while maintaining high performance metrics like a 12 kg horizontal work load and a 400 mm/s maximum speed.
High Precision Slide Table FAQs
What is the main advantage of the LESYH series compared to the standard LESH models?
The LESYH is a high-precision variation that offers significantly improved positioning repeatability (±0.01 mm) and a dramatic increase in vertical work load capacity (up to 20 kg).
What motor types are available for the LESYH slide table?
It is available in three main configurations:
- AC Servo Motor: High-speed performance with incremental or absolute encoders.
- Battery-less Absolute Encoder: Maintains positional awareness without a battery backup.
- Motorless Type: Compatible with motors from over 18 manufacturers.
What is the maximum work load for the LESYH series?
The maximum work load depends on the orientation:
- Horizontal: Up to 12 kg.
- Vertical: Up to 20 kg.
What are the speed and acceleration capabilities of these rotary tables?
The actuators offer high-speed, shock-less actuation with a maximum speed of 420°/sec and a maximum acceleration/deceleration of 3,000°/sec².
What is the difference in deflection accuracy between the basic and high precision types?
- The high precision type significantly reduces table deflection:
- Basic Type: 0.1 mm deflection on the top and external surface.
- High Precision Type: 0.03 mm deflection on the top and external surface.
What are the available body sizes and stroke lengths?
The series comes in body sizes 8, 16, and 25. Stroke lengths are available at 50, 75, 100, and 150 mm (specific availability depends on the body size).
What is the maximum speed and acceleration?
The LESYH can reach speeds up to 400 mm/s in standard configurations and up to 800 mm/s in high-performance configurations. Maximum acceleration is 10,000 mm/s² for horizontal applications and 5,000 mm/s² for vertical.
What is the maximum pushing force?
The actuator can deliver a maximum pushing force of 385 N to 420 N, depending on the specific model and size.
What motor mounting positions are offered?
To fit different machine footprints, the motor can be mounted in-line with the table, or in parallel to the left or right side.
Can the workpiece be mounted on multiple surfaces?
Yes, the work table is designed with mounting surfaces on both the top and the front, providing flexibility for various attachment needs.
