ACK-090-04
The Copley Controls ACK-090-04 module is a precision digital servo drive from the Accelnet CanOPEN Modules series. Featuring a MOSFET 3-phase inverter with a 15 kHz center-weighted PWM carrier, it delivers continuous output power of 0.18 kW and supports an input power voltage range of +14 to +90 Vdc. This compact drive (dimensions 63.5 x 40.6 x 21.1 mm) weighs only 1.3 oz (37 g) and is engineered for motion control applications requiring high-speed communication, precise current regulation, and programmable outputs for brake control.
In detailed operation, the ACK-090-04 provides a current loop update rate of 15 kHz and a position & velocity loop update rate of 3 kHz for responsive performance. Continuous current output is 2 Adc (1.4 Arms sinusoidal), with peak current capability of 4 Adc (2.8 Arms sinusoidal). The module integrates full-duplex RS-232 communication (9,600 to 115,200 Baud) and high-speed CANopen via a TJA1050 transceiver. Overvoltage protection at +91 Vdc and undervoltage protection at +14 Vdc safeguard the drive, while drive outputs resume operation only when HV levels return to safe thresholds.
The ACK-090-04 conforms to EN 55011, EN 61000-6-1, IEC 61010-1, and UL 61010-1 standards, ensuring robust electromagnetic and safety compliance. Its drive over temperature protection activates at PCB temperatures above 90 °C, and shock resistance meets IEC 60068-2-27 (10 g, 10 ms, half-sine pulse). An internal +5 V DC output (250 mA) supports auxiliary circuits, with recommended L-C filtering for stability. Programmable inputs monitor motor overtemperature and drive brake releases, while external flyback diodes manage inductive loads. This durable, efficient module streamlines integration into industrial automation, delivering reliable, precise control for demanding motion control systems.
