Product Description:

This STL-075-03 Drive compact drive boasts dimensions of 64 x 41 x 16 mm [2.5 x 1.6 x 0.6 in], making it suitable for space-constrained applications. It weighs a mere 1.3 oz (0.037 kg). The drive operates on an input voltage ranging from +20 to +75 Vdc, with the added benefit of being transformer-isolated. Dual MOSFET H-bridges power the drive, employing a 15 kHz center-weighted PWM for smooth operation. You'll find a peak current of 3 Apeak (2.1 Arms, sinusoidal) and a continuous current rating of 2 Apeak (1.4 Arms, sinusoidal) are achievable with this device. Control is facilitated through an RS-232 port, supporting speeds from 9,600 to 115,200 Baud. The drive excels in demanding environments, exhibiting a wide operating temperature range spanning 0 to +45°C. Moreover, it can be safely stored in temperatures from -40 to +85°C.

Advanced control capabilities are provided through a multitude of modes including Indexer, Point-to-Point, PVT, Camming, Gearing, Position, Velocity, and Torque. Communicating through the widely adopted CANopen protocol (DS-301 V4.01 compliant to EN 50325-4) ensures seamless integration into various systems. Consider the comprehensive protection features integrated into the drive: over-voltage, under-voltage, over-temperature, and short circuit protection. Should the drive's temperature reach 90°C, a thermal shutdown mechanism activates, preventing damage. This robust protection ensures longevity and reliable performance in industrial automation environments. This drive truly shines in applications requiring precision and dynamic motion control.

Environmental considerations are met with agency standards conformance to EC Directive 2014/30/EU (EMC Directive), EN 55011, and EN 61000-6-1. Notably, this compact drive is not only efficient, but is also surprisingly robust thanks to its comprehensive protection against electrical faults and thermal overload. Such features ensure its suitability for a broad range of industrial automation applications. It's worth noting the efficient cooling system allows for optimal performance within the specified temperature range, contributing to the drive's overall reliability and longevity.
