<Delivery Notice>

Fastec products are made to order, which may require an additional 2 to 4 weeks for production.

For this reason, cancellations or modifications are not possible once an order has been placed.

We will provide you with the confirmed production and delivery schedule after the order has been placed (manufacturing starts)

<Discription>

The EZI-SERVOII-CL-28L-D is a miniature, high-performance closed-loop stepping motor system designed for precision applications where space is extremely limited. As the "L" (Long) version of the NEMA 11 (28mm) series, it delivers the maximum possible holding torque (0.118 N·m) for this frame size. This specific model features the specialized "D" Type (16,000 PPR) optical encoder, making it an ideal solution for compact semiconductor equipment, medical devices, or lab automation requiring high-resolution network control.

Key Features

• High Torque in Miniature Size: Despite its tiny 28mm flange, the Long stack design (50mm length) allows it to produce 0.118 N·m of torque, providing robust performance for miniature mechanisms.

• Specific High Resolution: Equipped with a 16,000 PPR (Pulse Per Revolution) encoder ("D" Type). This offers a distinct resolution setting compared to standard A (10,000) or B (20,000) types, suitable for specific gear ratios or precision requirements.

• Closed Loop System: Continuously monitors motor position to prevent step-out (loss of synchronization), ensuring reliability even during rapid moves or load fluctuations.

• Network Ready (CL Series): Designed for integration with CC-Link based control systems, facilitating high-speed fieldbus communication and reduced wiring complexity.

• No Hunting: Maintains a perfectly stable stop position without oscillation, which is critical for high-magnification optical stages and grippers.
