Product Description:
The ASP-090-18 is a digital servo drive manufactured by Copley Controls as part of the Accelus Servo Drives series. In an automation cell, it receives analog or pulse command references, closes current and velocity loops, and delivers three-phase power to brushless motors so that axes follow commanded torque, speed, or position profiles with minimal error. Its compact design lets machine builders place the amplifier close to the motor, shortening cable runs and improving electromagnetic immunity in multi-axis packaging, material-handling, or semiconductor equipment.
During continuous operation, the drive can supply 0.53 kW of mechanical power while sourcing 6 Adc per phase to the motor windings; this operating level draws 6.7 Adc from the DC bus. Short bursts are handled by a peak capability of 18 Adc per phase for up to 1 second, supported by a 20 Adc input limit. The current loop updates at 20 kHz, allowing tight regulation even on low-inductance motors, and modulation is further smoothed by a 40 kHz PWM ripple frequency. A minimum on-time of 220 ns prevents pulse truncation at small duty cycles. The 12-bit analog reference path preserves fine resolution when the drive operates in torque or velocity modes.
For rapid start-stop profiles, the unit can deliver a peak mechanical output of 1.55 kW. Command throughput keeps pace with modern motion controllers through a maximum position command rate of 2 MHz and a velocity and position loop that closes at 4 kHz. Incremental encoders operating at up to 5 million lines per second are accepted, while the differential reference input presents a high-impedance load of 66 kΩ so upstream digital-to-analog converters are not overburdened. These control rates allow the drive to process rapid position updates while maintaining responsive velocity regulation. The high-impedance reference input also reduces loading on the external command source during torque-controlled and velocity-controlled operation.
