Curtis Model 1238 provides advanced control of AC induction motors performing on-vehicle traction drive or hydraulic pump duties. It offers vehicle developers a highly cost-effective combination of power, performance and functionality. Application: Designed primarily for use on medium to large material handling vehicles such as counterbalance or warehouse trucks. The Model 1238 is also intended for use on all heavy-duty applications such as Tow Tractors and Airport Ground Support Equipment (GSE). 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 1238 is a CANopen compatible and provide 20 VCLconfigurable CAN ‘mailboxes’, 6 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 displays and thus control and monitor the entire system. Features: Increased Performance, Improved functionality • Higher performance form, fit and functional replacements for 1238 AC controllers. • CE marked as a programmable safety device under EN ISO 13849-1. • Models available for 350–800A output at 24–96V system voltages. These are true 2 minute RMS ratings, not short duration ‘boost’ ratings. • 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.
