<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-56S-B is the most compact model in the NEMA 23 (56mm) closed-loop stepper series. The "S" (Short) designation means it has the shortest body length (approx. 42mm), designed specifically for applications where installation space is extremely limited but high precision is required. Despite its small size, it features the advanced "B" Type (20,000 PPR) optical encoder, offering superior positioning resolution.

Key Features

• Ultra-Compact Design: With a short body length, this motor fits into tight spaces where standard "M" or "L" motors cannot, making it ideal for small XY stages or compact medical devices.

• Ultra-High Resolution: Equipped with a 20,000 PPR (Pulse Per Revolution) encoder, providing extremely fine control (0.018° per step) for high-precision tasks.

• Closed Loop System: Continuously monitors position to ensure no loss of synchronization (step-out), maintaining reliability even in a compact form factor.

• No Gain Tuning: Ready to operate out of the box without the complex PID tuning required for servo motors.

• Stable Stop: Holds its position perfectly without oscillation (hunting), essential for applications requiring vibration-free stopping.
