Product Description:
The AMP-090-09 is a compact, DC-powered servo amplifier from Copley Controls and is part of the Accelnet CANopen Modules series. It interfaces with CANopen networks to regulate brushless or brushed servomotors in automated machinery. The amplifier converts motion commands into accurate phase-current drive signals for precise axis control on production lines. Its embedded intelligence provides motor protection and diagnostic feedback during continuous industrial operation.
The AMP-090-09 operates from 20 to 90 V DC bus supplies, allowing it to work with low- and mid-voltage power sources. This broad voltage range accommodates the DC buses commonly used in industrial machinery. Under continuous duty, it delivers 3 A DC per phase and can furnish 9 A DC for bursts lasting 1 second when higher dynamic torque is required. The input stage tolerates 10 A DC during these peak-demand periods. Torque regulation is performed by a current loop operating at 16 kHz, while the velocity loop operates at 4 kHz to align motor speed with programmed motion profiles. These closed-loop rates support stable control of modern servo windings with low inductance.
The output stage uses a PWM carrier frequency of 32 kHz, which helps keep current ripple low with the module’s 0.075 Ω phase resistance. Two differential analog command channels are digitized at 12-bit resolution and buffered by a 5 kΩ input impedance to limit loading on upstream signal sources. Ten high-speed inputs and one motor-temperature input capture limit-switch and thermal data. Three general-purpose outputs and one high-speed output return operating status to connected controllers. Optical communication over 1,300 nm fiber supports noise-resistant daisy-chain layouts in electrically noisy machinery. The housing measures 196.3 × 99.1 × 29.7 mm, allowing the amplifier to fit inside shallow control enclosures where available mounting depth is limited.
