ACS4820-700F by Kollmorgen

The Kollmorgen ACS4820-700F motion control unit is a robust device in the AC SuperDrive Motion Units series designed for high-precision industrial automation. It provides flexible 1, 2, or 4 quadrant control and operates on a 48 V nominal DC supply voltage to power both induction and synchronous motors. With an IP65 protection rating, this unit is purpose-built for harsh environments and outdoor installations. It supports both speed and torque control modes for variable load requirements and offers a high level of efficiency and operational precision. The modular design of the ACS4820-700F ensures seamless integration into existing control architectures.

Detailed technical specifications underscore its adaptability and performance. The ACS4820-700F conforms to EN 1175-1 and UL 583 applicable standards and communicates via CANopen protocol alongside analogue and digital inputs. Power connections utilize M6 bolts for secure DC link wiring, while signal and control interfaces connect through an AMP SEAL 23-pin connector with sealed contacts. It supports both a 3-phase induction motor, squirrel-cage rotor and a permanent magnet synchronous motor, enabling versatile motor selection. Switching frequency options of 8, 12, 16 kHz allow a trade-off between noise reduction and continuous power ratings (all performance ratings based on the 8 kHz setting). The unit operates over an ambient temperature range of -40 °C to +55 °C and can be stored from -40 °C to +70 °C with up to 95% RH storage humidity.

Operational features deliver precise control and reliability under demanding conditions. Four quadrants of operation permit forward/reverse motoring and braking, while dedicated connectors facilitate quick selection between speed or torque control modes. The sealed IP65 housing prevents dust and water ingress, ensuring dependable function in dusty, wet, or outdoor locations. Customizable switching frequencies reduce acoustic noise at higher settings, albeit with proportional changes in continuous current capacity. Analogue and digital I/O expand configuration options for feedback signals, alarms, and external interlocks, enabling adaptive performance tuning through software parameters.

System integration is streamlined via the CANopen communication protocol, allowing the ACS4820-700F to interface with PLCs, motion controllers, and SCADA platforms. The robust AMP SEAL connector and IP65 ingress protection make it suitable for conveyor systems, packaging machinery, and mobile equipment. Its support for both induction and synchronous motors broadens application scope across robotics, material handling, and process automation. Designed for industrial environments, the ACS4820-700F meets stringent safety and reliability standards, making it ideal for manufacturers requiring precise, durable motion control solutions.
