Servomotor with integrated controller CM3+-17L50A

AC24 Vindustrial

Overview
COOL MUSCLE 3+ is the integrated servo system equipped with devices such as driver and controller required for motor control. A periodic calculation processing function enables conditional branch processing and arithmetic processing according to operating conditions and the external environment. The motor (CM3+) itself can operate autonomously, contributing to lower total system cost.

Simplification by Autonomous Distributed Control
Autonomous distributed control is possible with CM3+, reducing the burden on a PLC. Host control systems can be simplified, costs reduced, and wiring can be omitted or eliminated for simple equipment or small systems.

Branch processing during positioning operation
CM3+ supports two types of programs: a 'Motion Bank' that describes operation sequences such as positioning, and a 'Logic Bank' that describes the overall sequence. These programs can execute concurrently, enabling conditional branch processing and arithmetic based on operating conditions and the external environment for more advanced control development.

High precision, speed, and torque at low cost
Achieves high precision, speed, and torque using simple commands from a familiar interface. Communication uses serial communication based on RS232C, so special equipment or software is not required.

Multi-axis network and wiring reduction
The network can be established by the Daisy Chain method. A multi-axis network up to 15 axes can be constructed simply by connecting the motors with cables, enabling wiring reduction.

Supports various control methods
Operation data can be set, selected, and executed from a host controller. Supported interfaces include I/O, RS232C, and Modbus (RTU) / RS485. EtherNet/IP communication was scheduled for release in 2022.

Higher torque compared to servo motors
While traditional servo motors require operation near rated torque (about 30% of maximum torque for certain torque-control use), CM3+ can be controlled within approximately 80% of the maximum torque. This allows reduction of motor size and realization of torque control systems at lower cost.
