RTA – GMD / GMH (EUROCARD) – Stepping Motor Drive

Introduction

• Stepping motor drives series with Step & Direction interface and realized with SMD technology in single EUROCARD format card (100×160 mm).
• System backward-compatible with the previous series (with PTH technology) equipped with a 32 pole, DIN 41612 form D connector. Drives designed to be assembled inside a RACK complete with motherboard.
• Target: multi-axes applications requiring backward-compatibility with the previous series.

Highlights

• Mechanical, electric and applicative backward-compatibility with the previous series drives.
• Electronic damping facility for further acoustic noise and mechanic vibrations reduction at low and medium speed.
• Standard input and output signals facilitate the interface with the most common control systems.
• Particular care dedicated to obtain top performance and low power losses for both the card and the motor, limiting the need for forced ventilation.
