Like all Curtis controllers, the E and SE models oer superior operator control of motor drive
performance. Features include:
• Closed-loop speed and torque control for both induction (ACIM) and surface permanent
magnet (SPM) motors.
• High eciency, eld-oriented motor control algorithms that enable maximum possible motor
torque generation for all operating conditions.
• Advanced Pulse Width Modulation technology for ecient use of battery voltage, low motor
harmonics, low torque ripple, and minimized switching losses.
• Extremely wide torque/speed range including full regeneration capability.
• Full eld-weakening capability with ACIM motors; full control up to no-load base speed
with SPM motors.
• Smooth low speed control, including zero speed.
• Adaptation of control algorithm to motor temperature variation for optimal performance
and reduced motor heating.
• Power limiting maps allow performance customization for reduced motor heating and
consistent performance over varying battery state-of-charge.
• ermal cutback, warning, and automatic shutdown provide protection to motor and controller.
• Insulated metal substrate power base provides superior heat transfer for increased reliability.
• Built-in auto-characterization routines for effective in-vehicle optimization of motor
performance and eciency.
• Powerful operating system allows parallel processing of vehicle control tasks, motor control
tasks, and user congurable programmable logic (VCL).
• A wide range of I/O can be applied wherever needed, for maximum distributed system control.
• Built-in Dual Drive soware allows easy setup and control of typical dual-drive vehicles,
without VCL.
• Internal battery-state-of-charge, hourmeter, and maintenance timers.
• CANopen compatible CANbus connection; other CANbus protocols are configurable
through VCL.
• Signicantly increased CAN master capabilities, VCL execution speed, and VCL code space
• Field-programmable, with ash downloadable main operating code.
• Easily programmable through the Curtis 1313 handheld programmer and 1314 PC
Programming Station.
• Rugged sealed housing and connectors meet IP65 environmental sealing standards for use
in harsh environments.
• Compliance with Machinery Directives 2006/42/EC and EN13849-1.
Getting the most out of your Curtis controller
Read and apply the information in this manual. e Installation/Wiring, Initial Setup, and Tuning Guide
chapters are critical to proper operation of your controller. For technical support, contact the Curtis
distributor where you obtained your controller or the Curtis sales-support oce in your region.
