Copley has extended the XENUS offline servo drive’s temperature, humidity, vibration and shock ranges to meet military COTS requirements, including Mil Standard #810. The Series R10, controls rotary and linear motors/actuators in extreme industrial environments. The hardened drives operate in stand alone and networked operating modes, and respond to a variety of input formats, including step-and-direction commands for upgrading from stepper motors to high torque servomotors. Operating modes also include indexing, point-to-point, PVT, PT, position, velocity, and torque control, as well as electronic camming and gearing. The drives are compatible with CANopen, RS422, and RS 485 communications, operate on single phase or three-phase 85 to 264V supplies, and deliver up to 3 kW drive power. The drives use the advanced carrier cancellation modulation (CCM) for utmost zero crossing linearity and ultra low ripple current, which occurs at twice the carrier (PWM) frequency. Ripple frequency is 28 kHz. Current loop bandwidth is 2.5 kHz. The amplifier provides 15 kHz current loop update rate (67 µs) and 3 kHz (333 µs) position and velocity loop update rate. R10 drives are available for peak current from 18A to 40A, and operate from 85V AC to 264V AC single or three-phase line voltages.
