Product Description:

The ASC-055-18 is a high-performance servo drive manufactured by renowned motion control technology provider Copley Controls. The servo drive supports a variety of operating modes that include position, velocity, and torque control. That makes it ideal for applications requiring precision motor control.

The ASC-055-18 servo drive can handle source voltages ranging from 20 to 55 VDC and offers a steady 6 A DC output current, as well as an 18 A DC peak voltage. This type of output uses space vector modulation at a frequency of 20 kHz to ensure effective motor control. The current loop update rate of 50 µs allows for faster and more precise functioning. The servo drive features two programmable digital outputs and six programmable digital inputs that allow for additional system customization. The commutation method enables precise and fluid motor control using field-oriented sinusoidal control. By automating tasks like motor phasing and current loop tuning, the auto-tuning and auto-phasing features streamline configuration and cut down on setup time. An RS-232 interface makes it easy to configure the software, which in turn makes it easy to control and set up the amplifier. Furthermore, it operates reliably under a wide variety of temperatures, from 0 to 70 degrees Celsius.

With its innovative design, the ASC-055-18 servo drive offers space-efficient PCB installation and has a strong field-oriented control system. Integrating it into PCB-mounted systems is a breeze, and it provides versatility for a wide range of industrial automation settings thanks to its small dimensions of 6.0 x 3.1 x 0.8 inches. Wake Industrial provides a one-year replacement guarantee and makes the products available to customers all over the world with global shipment choices.
