Choice of Motor Technologies
The Gen4 controllers are designed for controlling both AC Asynchronous motors and PM Synchronous motors. This feature allows users to select optimal motor solutions for any application. Both UVW and encoder AB inputs are provided for maximum flexibility.

Integrated I/O
This unit includes a cost-effective, fully integrated set of inputs and outputs (I/O) designed to handle a wide range of vehicle requirements. This eliminates the need for additional external I/O modules or vehicle controllers and connectors,

Self-characterization
Sevcon’s unique Self Characterization capability enables Gen4-series controllers to automatically define and optimize parameters for the AC motor. This feature provides quick set-up and allows customers to select motor suppliers of their choice without worry-ing about compatibility between controller and motor.

Fully CANopen Compliant
These controllers come standard with CANopen. This allows easy inter-connection of controllers and other devices such as displays and driver controls. CANopen also allows the user to wire the vehicle to best suit vehicle layout since inputs such as the throttle can be connected to any of the controllers on the vehicle and the demand value will be passed over the CAN-open bus to the relevant motor controller.
