Sensitron has introduced SensINTNet, a Multi-Axis Motor Controller System that is a complete drive network solution for multi-axis systems requiring network control with a high-level of integration. This product is ideal for use in leveling/gyro systems, sequencing pumps, blowers, fans, and hatch controls in the defense, industrial, automotive, aerospace, and commercial marine markets.

Multi-Axis Motor Controller SystemThe SensINTNet Multi-Axis Motor Controller System is a complete drive network solution for multi-axis systems requiring network control with a high-level of integration. The system consists of one or more Controller Module (CM) assemblies, each controlling up to ten independent motor Drive Module (DM) nodes. The CM nodes communicate with a Main System Host via a 10/100 Copper Ethernet link using TCP/IP protocol, and relay messages to the DM network via J1939 compliant CAN network.

A single Controller Module (CM) supports one or multiple motor Drive Modules (DMs). The Controller Module (CM) is comprised of two microcontrollers, one for each of the communications interfaces – Ethernet TCP/IP stack, and SAE J1939 CAN protocol bus. The CM receives the Ethernet commands from the Host Computer (HC) and passes the commands and data to DM nodes via the CAN interface.

The motor Drive Modules autonomously drive the individual axis to commanded position using torque (current) limited speed control – from an open to closed position, or from a closed to open position. During the movement, the motor shaft speed remains constant. The shaft’s torque is controlled and limited, varying the speed as necessary to accommodate this limit. If necessary, four quadrant operation and/or braking may be used to halt the motor within the time requirement. The motor drive circuit is compatible with a 6-step Brushless DC (BLDC) motor utilizing Hall feedback sensors.
