A range of controllers (inverters) for the speed and torque control of 3-phase AC motors. Intended for use as electric traction or hydraulic pump motor controllers for mobile, on-vehicle applications that use a SERIES . 24-96 VDC nominal battery supply. Logos Curtis MarCom 2014. The SE' Advantage The Curtis SE' AC controllers utilize the latest technology to increase the peak current ratings for each size of controller. For a given rating, the SE. models are smaller and lower cost than previous Curtis AC controllers, benefits that are highly advantageous for all types of applications. Only Curtis AC can offer: Model 1232SE. Curtis VCL Vehicle control Language is an easy to use programming language that allows vehicle developers to write powerful logic functions and create a virtual system controller.

2 ' Curtis offers customers VCL development tools and training. Curtis also provides a VCL service where Curtis engineers will work with the OEM. to create any custom VCL code required. field oriented control (FOC) algorithms generate the maximum possible torque and efficiency across the entire speed range. Advanced Curtis control provides superb drive feel', improved speed regulation and increased gradeability. Model 1234SE. Motors Easily configured to work with any AC induction or PMAC motor . Improved motor auto-characterization setup allows simple on-truck pairing with different Induction motor types. In addition, a comprehensive library of induction and PMAC motor types are conveniently stored in the controller memory. Dual-Drive Functionality is standard, allowing correct control of applications featuring twin traction motors. This function ensures smooth and safe operation, minimal tire wear and correct load sharing between the traction motors at all times.

3 Configurable CANbus connection allows communication with Model 1236SE. other CANbus enabled devices. They are CANopen compatible and provide 24 VCL-configurable CAN mailboxes' 10 more than earlier Curtis AC controllers. Integrated System Controller More than just a motor controller, they are also powerful system controllers. They feature a comprehensive allocation of multi-function I/O pins for use as analog inputs, digital inputs, contactor coil drivers and proportional valve drivers. In addition to this local I/O, these controllers can use VCL to map and configure the remote I/O available on other CANbus devices, send messages to CAN.
