Product Description:
The ACM-180-20 is a compact high performance digital servo drive manufactured by Copley Controls. It integrates seamlessly into applications requiring precise current, velocity and position control. This servo drive supports both networked and stand alone operations for a wide range of motion control solutions.
The Accelnet series digital servo drive features a current loop update rate of 15 kHz to ensure smooth and efficient operation. Its small signal current loop bandwidth is typically 2.5 kHz that is subject to tuning and load inductance. The model offers a position and velocity loop update rate of 3 kHz to provide quick responsiveness. The model is equipped with two current sinking MOSFET open drain digital outputs each with a 1 k pull-up to +5 Vdc. The drive can handle up to 1 A of current sink. These outputs are programmable for high or low active levels through the CME software. The model’s primary command interface is via the CANopen bus although it can also process digital or ± 10 V commands in stand alone mode. This servo drive is an ideal solution for applications requiring precise control and high-speed updates.
The ACM-180-20 digital servo drive is compact, measuring 4.05 x 2.62 x 0.92 inches and weighing just 5.7 ounces. Its operating temperature range spans from 0 to +45 °C with storage tolerances of -40 to +85 °C. This design of the servo drive ensures optimal performance under varied environmental conditions. It supports cooling options like low profile heatsinks or Socket-A compatible chip-coolers with fans for enhanced cooling capacity for thermal management. The servo drive's versatile mounting design makes it suitable for integration close to motors with minimal cabling.
