SOMANET Drive 300

B.1

Overview

The SOMANET Drive 300, initially called Drive DC 900, implements latest power transistor technology to enable a node to efficiently drive one brushless DC motor with up to 360 W. Alternatively, 2 brushed DC motors can be driven in differential drive applications. Up to 3 brushed DC motors are possible, if only one direction is required. Hall-effect based current sensors on two phases, together with a high-quality ADC enable sophisticated control concepts such as sensorless torque control or field-oriented control/commutation. Being equipped with a quadrature encoder interface and a port with SPI, ADC input and GPIOs, the module supports any external sensor that may be required by your application.

Due to the modular characteristics of SOMANET Nodes, Drive modules can be configured with various processing units as well as communication modules. In combination with the open-source SOMANET firmware components for high-end motor control, Drive modules are the key to the most flexible motor and motion control solution available.

Important

Depending on the specific application and the load attached, the system’s power supply must be designed accordingly to dispatch energy that is generated by the motors during braking, or an additional fast responding chopper device needs to be installed to the supply chain. This especially applies to 48V setups.

Please take care for the maximum voltage rating of this Drive module, as higher voltage spikes can occur during braking. Please ask Synapticon Application Engineering for assistance and further advice on this topic.

Power Supply

When the Drive 300 is included in a SOMANET device, this one provides power to the remaining boards assembled on top. For that, you simply need to supply the rated voltage on the power terminals of your Drive 300.

Depending on the specific application and the load attached, the system’s power supply must be designed accordingly to dispatch energy that is generated by the motors during braking, or an additional fast responding chopper device needs to be installed to the supply chain.
