CURTIS DC SepEx Motor Controller

Model: 1268-5411, 36-48V / 400A, working with ITS (inductive throttle sensor) Throttle

Parameter List of 1268-5411

1268-5411 is an OEM DC SepEx motor controller for E-Z-GO / CUSHMAN / TEXTRON / TITAN golf carts & utility vehicles. The controllers 1268-5411 that we supply are made by a Chinese manufacturer, fully compatible with CURTIS controllers 1268-5411 (E-Z-GO part number 611173).

1268-5411 controllers are programmable devices, working with CURTIS 1313-4331 handheld programmer and 1314-4402 PC station programmer. For controller setting details, please take a look at  parameter list of controller 1268-5411 (PDF format).

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.

Key Features:

• CURTIS Model: 1268-5411 (E-Z-GO part number 611173)
• Norminal Battery Voltage (Volts): 48V (default setting) or 36V
• Amature 2 minute current rating (amps): 400
• Field 2 minute current rating (amps): 50
• Logic enable and logic power input voltage (minimum): 16.8 V
• Logic enable and logic power input current (no contactors engaged): 160 mA without programmer; 200 mA with programmer
• Logic input voltage: 20.0 V High; 7.5 V Low
• Logic input current 10 mA
• Throttle: ITS (inductive throttle sensor) type throttle,
• Dimensions: L229xW178xH81 mm
• Net Weight: 3.9 kg
• Package environmental rating: IP64, IP67

Specifications:

• PWM operating frequency: 16 kHz
• Electrical isolation to heatsink (min.): 500 VAC
• KSI input voltage (minimum): 16.8 V
• KSI input current (typical): 160 mA without programmer; 200 mA with programmer
• Ambient operating temperature range: -40°C to 50°C
• Heatsink overtemperature cutback: starts at 85°C; cutoff at 95°C
• Heatsink undertemperature cutback: 50% armature current at -25°C

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

The 1268-5411 serves as a DC SepEx traction motor speed controller in various E-Z-GO / CUSHMAN, TEXTRON / TITAN golf cart and utility vehicle models across different production years.

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.
