CURTIS DC SepEx Motor Controller

Model: 1268-5403, 36-48V / 400A, working with 3-wire potentiometer throttle and 0-5V voltage throttle

Overview:

CURTIS 1268 controllers are separately excited motor speed controllers designed for use in a variety of transport vehicles. These programmable controllers are simple to install, efficient, and cost effective. Typical applications include heavy-duty golf carts, personnel transports, burden carriers, and other utility vehicles.

The 1268 controller offers smooth, silent, cost effective control of motor speed and torque. The speed sensor input allows superior closed-loop control for regulating vehicle speed. Unique braking parameters allow simple, intuitive deceleration tuning. A full-bridge field winding control stage is combined with a half-bridge armature power stage to provide solid state motor reversing and regenerative braking power without additional relays or contactors.

Various throttles can be used with the 1268-5403 controller, including 5kΩ 3-wire potentiometers and 0-5V throttles. But 1268-5403 does not support ITS (Inductive Throttle Sensor) type throttle. So 1268-5403 can not be used as a direct replacement of an old 1268-5404, 1268-5411 or other 1268 controller model which works with ITS type throttle. For replacing 1268-5404, 1268-5411 or other ITS 1268-54xx controllers, you need a new throttle which works with 1268-5403, for example:

• FT-02YG: ITS throttle but with a regulated 0-5V voltage output
• JSQD-DWK-003D: 3-wire 0-5K potentiometer
• HXJS-4805: 0-5V voltage throttle
• RJSQ-001: 0-5V voltage throttle
• ET-126 MCU: CURTIS 0-5V voltage throttle with directional signals (forward / reverse)

Terminal installation kit & mating connectors:

Features Include:

• Regenerative braking, providing longer operation on a single battery charge and reducing motor brush wear and motor heating
• Adjustable brake rates, for smooth pedal-release braking
• Two user-selectable vehicle operating personalities, with vehicle top speed controlled and limited in each mode
• Motor parameters are programmable to match the characteristics of the specific motor being used
• Vehicle speed control is enhanced through feedback from a Hall effect speed sensor
• Anti-rollback function, providing improved control when throttle is released on hills
• Anti-stall function helps prevent motor commutator damage
• High pedal disable (HPD) and static return to off (SRO) interlocks prevent vehicle runaway at startup
• Complete diagnostics through CURTIS 1313-4331 Handheld Programmer or 1314 PC Programming Station and through the built-in Status LED, for quick and easy testing, diagnostics, and parameter adjustment
• WalkAway™ braking feature limits any stopped or key-off rolling to a very low speed
• Auxiliary driver can be programmed for either an electromagnetic (EM) brake or a WalkAway™ relay
• Coil driver provides adjustable pull-in and holding voltages to WalkAway™ relay or EM brake
• Two fault outputs provide diagnostics to remotely mounted displays
• Reverse signal driver provides a low signal any time the vehicle is traveling in reverse
• Driver outputs are short circuit protected and provide built-in coil spike protection
• Brake/Drive Interlock meets ISO stopping distance requirements
• Warning buzzer sounds steady in reverse, intermittent during WalkAway™ braking
• Splash resistant plastic cover
• Meets or exceeds EEC fault detect requirements

1268-5403 controllers are widely applied in different electric vehicles, such as golf carts and utility vehicles. For current golf cart user, please take a reference with  the parameters' list of different vehicle models (JPEG format); for comparing the difference of parameters modified, please see the parameter list of default setting of controller 1268-5403 (PDF format):

A speed sensor is required for use with 1268 controller. The speed sensor must be of a pulse type, and must interface to the controller with an open collector NPN transistor output. The most common sensor type will be a Hall effect switch IC, such as the Allegro type UGN3132 or Micro Switch type SS11; these work with an eight-pole (four pulses per revolution) ring magnet attached to the motor shaft. Other pole configurations can be accommodated by programming the Tacho Poles parameter to match the sensor magnet. Linear output sensors such as PM tachogenerators and variable reluctance gear tooth sensors (“magnetic pickups”) are unsuitable.

Notice: For the buyer without CONTROLLER APPLYING EXPERIENCE, please consult your cart/motor dealer and read carefully the 1268 Controller Manual (PDF format) before making the purchase.

Notice: If you need to modify any controller parameter, please send us a message with the list of parameters to be modified (Click here to download the parameter list of default setting of controller 1268-5403, PDF format).

Notice: We supply also the 1268-5403 controller assemblage with throttle (foot pedal).
