Product Name
ACOPOSmulti single-axis inverter module, wall-mount cooling version.
Product Introduction
This inverter operates from the ACOPOSmulti common DC bus and drives synchronous servo or induction motors through PWM output stages. It is designed for modular multi-axis automation systems requiring centralized DC supply, regenerative energy sharing and plug-in safety/network options.

Working Principle
DC bus energy is switched by insulated power devices at the selected PWM frequency to produce three-phase motor voltage and current. The control section manages current regulation, encoder/resolver feedback, brake control and safety communication with the automation system.
Installation Requirements
- Mount on suitable wall plate with B&R backplane and required clearance for airflow
- Connect DC bus only after verifying discharge and insulation tests
- Install option cards, motor cables and shielded encoder cables per B&R wiring rules
- Configure node address, motor parameters, switching frequency and safety functions in Automation Studio or drive engineering tools
Usage Precautions
- Wait for DC-link discharge and verify voltage below safe limit before service
- Higher PWM frequency reduces continuous current; apply thermal derating
- Do not exceed brake voltage, current and cable length recommendations
- Use approved B&R motor and cable combinations to maintain EMC and insulation limits
