CURTIS Permanent Magnet Drive Motor Speed Controller

Model: 1212S-2601, 24V / 110A, with status LED

Can replace 24V / 90A 1212S-2501

Overview:

The CURTIS 1212S-2601 (CURTIS P/N 17729710) is motor speed controller provides precise and smooth control of permanent magnet drive motors for battery powered vehicles. This controller is designed for use in pallet truck applications.

The 1212S-2601 controller is fully programmable, via the CURTIS Model 1313-4331 Handheld Programmer or 1314 PC Programming Station. Use of the programmer offers diagnostic and test capability as well as configuration flexibility.

For more information about controller's parameters, please see parameter list of CURTIS controller 1212S-2601.

Like all Curtis motor controllers, the 1212S offers superior operator control of the vehicle’s motor drive speed.

Key Features:

• CURTIS model: 1212S-2601 (also used as replacement of 24V / 90A 1212S-2501)
• Norminal Battery voltage (Volts): 24V
• 20 second current rating (amps): 110
• 2 minute current rating (amps): 70
• 1 hour current rating (amps): 50
• Peak boost current (amps): 150
• Max boost current duration: 10 second
• Minimum motor resistance: 120 mΩ
• EM brake coil resistance (min.): 20 Ω
• KSI input current (max): 250 mA
• Logic input current (max): 1 mA
• Minimum motor resistance: 120 mΩ
• Lift Lockout output current (max.): 1.5 A
• BDI output voltage, resistance (max.): 0–5 V, 10 kΩ
• PWM operating frequency: 15.6 kHz
• Electrical isolation to heatsink (min.): 500 VAC
• Storage ambient temperature range: −40°C to 85°C
• Operating ambient temp. range: −25°C to 50°C
• Overvoltage cutoff: 34V
• Either a resistance throttle or a voltage throttle can be used with the 1212S-2601 controller. The controller can accept a single-ended or inverse single-ended input signal from the throttle, depending on how the Throttle Type parameter is programmed.
  • Voltage throttles:
    • 0 = single-ended; neutral when wiper ≤Neutral Deadband setting
    • 1 = inverted single-ended; neutral when wiper ≥Throttle Max setting
  • Resistive throttles
  • 2 = single-ended; neutral when wiper is at Pot Low side
  • 3 = inverted single-ended; neutral when wiper is at Pot High side
• Dimensions: 79 × 141 × 47.5 mm
• Net Weight: 0.45 kg
• Regulatory compliance:
  • EMC: EN12895:2000
  • UL List: UL583
  • Safety: EN13849-1(PL=B, Cat 2)
• Package environmental rating: ISTA 2A; electronics sealed to IPX5

Features Include:

• Smooth and Secure Control
  • Advanced speed regulation maintains precise speed over varied terrain, obstacles, curbs, and ramps
  • Linear cutback of current ensures smooth control, with no sudden loss of power during undervoltage or overtemperature
  • Proprietary algorithms help prevent gearbox wear while providing smooth starts and reversals
  • The vehicle is brought to a complete stop before the electromagnetic brake is applied, ensuring safe and secure stops under all conditions
  • Charger inhibit input prevents driving while charger is attached
  • Key Off Decel function ensures a smooth “brake to stop” when the key is turned off while driving or when a fault occurs that requires the vehicle to stop
  • Anti-Rollback/Roll-forward function provides smooth and safe vehicle control on hills and ramps
  • Internal main relay provides secure power-off
  • Boost current gives a brief boost of current greatly improving transient loads such as starting on a hill, crossing thresholds, etc.
• Easy Installation and Setup
  • Industry standard footprint, mounting centers, and wiring allows drop-in replacement of other controllers
  • 1212S controller is easily programmable through the CURTIS Model 1313-4331 Handheld Programmer or 1314 PC Programming Station, or can be supplied pre-programmed
  • Accepts standard single-ended voltage/resistance throttles
  • Throttle sense can be inverted for all throttle types
  • Simplified troubleshooting and diagnostics
  • Standard Molex Mini-Fit-Jr. terminals provide proven connections for the control wiring
  • Bolt-on terminals provide robust connections for the high current wiring
• Valuable Additional Features
  • Automatic compensation for changes in motor condition to ensure optimum drive performance at all times
  • Multi-mode provides for two distinct and programmable control modes (indoor/outdoor)
  • Emergency reverse with belly button switch input
  • Emergency stop provides immediate EM braking when throttle transitioned through neutral to >80% reverse request
  • Lift Lockout input from Curtis 906 battery discharge indicator meter
  • Output Lift Lockout signal, which can drive a pump contactor
  • Pump SRO can be enabled to prevent pump startup when KSI first turned on
  • Sleep function prevents the controller draining the battery when the vehicle is inactive
  • Battery Discharge Indicator output
  • Adjustable brake hold voltage reduces heating of the brake coil
  • Reverse polarity protection
• Robust Safety and Reliability
  • High RF immunity prevents speed variation and shutdowns in noisy RF environments
  • Controller power circuits and microprocessor software are continuously monitored for proper operation
  • On power-up, system automatically checks the throttle, brake, and associated wiring, and disables drive if a fault is found
  • Whenever the 1212S senses a loss of KSI or any fault that requires a stop, it smoothly decelerates the vehicle to a stop
• Meets or Complies with Relevant US and International regulations
  • Electronics sealed to IPX5
  • Designed to meet EN12895:2000, EN13849-1(PL=B, Cat 2), and UL583.
