AC INDUCTION MOTOR CONTROLLER MODEL 1232E 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 1232E is CANopen compatible and provides 20 VCL-configurable CAN ‘mailboxes’, 6 more than earlier Curtis AC controllers. The ‘E’ difference A significant enhancement to the Curtis AC family, The ‘E’ models utilize a powerful dual-microprocessor logic architecture to provide improved performance and surpass the requirements of the latest international functional safety standards. •• 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. DESCRIPTION FEATURES The Curtis model 1232E provides advanced control of AC Increased Performance, Improved functionality induction motors performing on-vehicle traction drive or hydraulic pump duties and offers the highest levels of functional safety. •• Higher performance form, fit and functional replacements for earlier Curtis Model 1232 AC controllers. •• Models available from 175A–250A output at 24–80V system voltages. APPLICATION The Curtis Model 1232E is intended for use as the traction controller on class 3 materials handling ‘walkies’ and other small industrial trucks. It is equally suitable as the pump controller for auxiliary hydraulic functions on larger industrial vehicles. •• Enhanced 64MHz micro and additional FLASH memory doubles the available VCL code space and provides more than twice the VCL execution speed. •• Six additional VCL-configurable CAN ‘mailboxes’ significantly increases CAN master capabilities. •• Advanced Pulse Width Modulation techniques produce low motor harmonics, low torque ripple and minimized heating losses, resulting in high efficiency. www.curtisinstruments.com
