Product Description

The model ACM-055-18 is a digital servo drive engineered for precision motion control applications. This drive is manufactured by Copley Controls. It offers robust control of brush and brushless motors. This drive integrates seamlessly into diverse industrial automation setups.

The ACM-055-18 digital servo drive supports CANopen networking and provides 100 % digital control of motor operations. It features a wide input power range from 20 V DC to 55 V DC with a capacity of 6 ADC continuous current and 18 ADC peak current. The device operates under the DSP-402 protocol (CANopen CiA-301 V4.2.0). It supports multiple motion profiles including Profile Torque, Profile Position, Profile Velocity and Homing. The model’s advanced control features include ± 10 V DC analog input to regulate Position, Velocity or Torque. The model ensures precise motion control with a current loop sampling rate of 15 kHz and velocity/position loops operating at 3 kHz. The PWM ripple frequency of 30 kHz minimizes electrical noise. The implementation of space vector modulation reduces motor power dissipation and enhances operational efficiency. Carrier cancellation modulation further mitigates ripple current and minimizes dissipation during idle states.

This Accelnet series servo drive offers ten configurable logic inputs for functionalities like CAN address configuration, enabling limit switches, motor temperature monitoring and encoder pulses. It includes two logic outputs for status reporting or brake control. Incremental position commands are facilitated through step motor controllers in formats such as CW/CCW or Pls/Dir. The digital drive also supports A/B quadrature inputs from master encoders for synchronized control or cam table driving. The servo drive supports both unregulated DC power supplies and regulated switching power supplies to ensure adaptability in various setups.
