I N T E G R AT E D A C T R A C T I O N & DC PUMP SYSTEM CONTROLLER MODEL 1298 Only Curtis AC can offer: • 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’. 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. • Indirect Field Orientation (IFO) vector control algorithm generates the maximum possible torque and efficiency across the entire speed range. Advanced Curtis IFO vector control provides superb drive ‘feel’, improved speed regulation and increased gradeability. • Curtis Auto-Tune function enables quick and easy characterization of the AC motor without having to remove it from the vehicle. Curtis AC controllers are fully compatible with any brand of AC motor. • 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. • Configurable CANbus connection allows communication with other CANbus enabled devices. Model 1298 is CANopen compatible and can be further customized and configured using VCL. DESCRIPTION The Curtis Model 1298 combines advanced control of AC induction traction motors with solid state DC hydraulic pump and proportional valve control. It offers vehicle developers a highly cost-effective combination of power and functionality in a very compact integrated package. APPLICATION Designed primarily for class III material handling vehicles, such as walkie stackers that require variable speed, or soft-start and softstop control of the lift and lower functions. • Integrated System Controller - More than just a motor controller, it is also powerful system controller. It features 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, this controller can use VCL to map and configure the remote I/O available on other CANbus devices, send messages to CAN displays and thus control and monitor the entire system. FEATURES Complete system control • High frequency, silent operation across the 0-300Hz stator frequency range. • Variable speed half-bridge DC pump output provides superior regulation of pump motor speed and current demand. • Fully programmable proportional valve and load-hold valve drivers. • Programmable options for variable speed or soft-start lift and lower modes. • Models available for 250A rms traction with 300A DC pump, or 300A rms traction with 350A DC pump. These are true 2 minute ratings, not short duration ‘boost’ ratings
