The Curtis model E provides advanced control of AC induction motors performing on-vehicle traction drive or hydraulic pump duties and offers the highest levels of functional safety. 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.

The Curtis Model P and S Motor Speed Controllers provide efficient, optimal control of permanent magnet drive motors for battery powered industrial vehicles. Optimized for use on light-duty Class III pallet trucks and similar electric industrial vehicles. The Curtis Model is a brushed DC permanent magnet motor controller for electric power steering, steer-by-wire systems and only works with Curtis VCL enabled AC traction controllers.
The steering motor functions as an actuator to change the angle of the wheel s thereby changing travel direction. Model interprets the steering command input and wheel position feedback, driving the steering motor to move the wheel to the desired position.
The Curtis Model E is a brushed DC permanent magnet motor controller for electric power steering and steer-by-wire systems. Designed to the requirements of EN The steering motor functions as an actuator to change the angle of the wheels thereby changing travel direction. Model E interprets the steering command input and wheel position feedback, to steer the vehicle.
The Curtis Model is a heavy-duty controller intended for demanding traction applications in hostile environments. These microprocessor-based MOSFET controllers add flexibility and versatility to the time-proven Curtis series motor controller family. Datasheets English Portuguese Spanish. The Curtis Model is a highly cost-effective hydraulic pump controller for use with series wound DC motors. It provides exceptional value for on-vehicle hydraulic pump motor applications such as scissor lifts and other types of mobile elevating work platforms.
This connec- tor is also used to implement the seat lift feature. When you want to use the programmer, unplug the seat lift connector and plug in the programmer. Page Throttle Wiring Throttle Type parameter is programmed; see page Wiring for the 3-wire pot, voltage throttle, and Curtis ET-XXX electronic throttle is described in the following text.
The ET-XXX throttle provides a single-ended 0—5V throttle signal and a signal indicating whether it is in forward or reverse.
Page Speed Limit Pot The push switch must go from off to on while the vehicle is stopped; if the push switch is turned on while the vehicle is moving, the electromagnetic Curtis Manual, Rev. Page Brake Release Switch The recommended resistor—designed to limit driver current to 15 mA when active—is 2. Alternatively, an LED with a built-in resistor can be used; it should be rated for 24V or 36V operation, depending on the controller model.
Page Battery Discharge Indicator A seat lift switch can be used to short Pins 1 and 3 of the 4-pin connector J9 , thus activating the throttle-controlled seat lift function. Seat lift should not be turned on while the vehicle is moving. For information on programmers, see Appendix C. Fault Beep Other Parameters Page Motor Parameters The minimum-speed forward acceleration rate is adjustable from 0. Acceleration rates under 0. The trade- off in increasing the soft start value is that acceleration response may be slowed somewhat, especially at higher values.
Page Braking Parameters The maximum-speed deceleration rate is adjustable from 0. Note: If a speed limit pot is not used in your application, see page Page 30 0. Page Throttle Gain The throttle gain parameter can be set with values from 1. A setting of 1. Page Fault Parameters 4 if the inhibit switch is activated while the vehicle is being driven.
If HPD is programmed Off, this protection feature is disabled. Page Brake Faults i. The seat lift switch connector plugs into J9 the 4-pin connector. The controller transitions from traction mode to seat lift mode when the seat lift switch is closed. Page Bdi Reset Voltage Although designed primarily to help end users with hand tremor prob- lems, this parameter can be used more generally to smooth out overall vehicle responsiveness for steadier driving.
Instructions for wigwag throttle centering using the Throttle Autocalibration parameter are presented on page Page 38 Select a direction and operate the throttle. The motor should begin to turn in the selected direction.
If it does not, verify the wiring to the throttle and motor. The motor should run proportionally faster with increasing throttle. If not, refer to Section 7. Before moving on to Section 5, Vehicle Performance Adjustment, be sure to set the back to its default setting.
The Curtis Manual, Rev. Page 41 Reverse acceleration and deceleration rates 6-e. First, set the. For low speed testing, we suggest that you Curtis Manual, Rev. Drive fast and suddenly release the throttle. You will experience the decel- eration behavior determined by the forward deceleration rate.
Page Adjusting Load Compensation 7-d. If the vehicle is still moving on a modest ramp when the brake gets set, is set too low. Page Fine-Tuning The Vehicle's Response Smoothness The tremor compensation function somewhat overlaps the gear softening functions. However, the tremor compensation function is active all the time, while the two gear softening functions are active only during a gear slack transition, i.
Tremor compensation is most noticeable when the throttle is moved quickly from full to small but non-neutral values.
