CURTIS Electric Power Steering (EPS) Controller 1220-2201

Typical application: EP, HANGCHA, HELI, BYD forklifts

The Curtis Model 1220 controller is designed to drive a brushed permanent magnet motor for electric power steering (EPS). The 1220 performs as the steering system controller, interpreting the steering command input and wheel position feedback, then driving the steering motor to move the steered wheel(s) to the desired position.

The steering motor must be speed reduced to get the high torque required to rotate the drive wheel. Typically this is done with a gearbox around 50:1 and a chain or gear with an additional reduction of around 4:1. The steering command comes either from a linear potentiometer or an analog voltage sensor. The wheel position feedback comes either from a linear potentiometer, an analog voltage sensor, or an encoder with a home switch.

The 1220 works only with Curtis AC traction controllers with embedded VCL. A "handshake" with the traction controller is required at startup to enable operation.

Intended applications are material handling vehicles such as reach trucks, order pickers, stackers, "man up" warehouse trucks, and other similar industrial vehicles.

Key Features:

• CURTIS model: 1220-2201
• Norminal Battery voltage (Volts): 24V
• 2 minute current rating (amps): 40
• 1 hour current rating (amps): 20
• Boost current (amps): 50
• PWM operating frequency: 15.6 kHz
• Electrical isolation to heatsink (min.): 500 VAC
• Storage ambient temperature range: -40° to 85°C (-40°F to 185°F)
• Operating ambient temperature range: -40°C to 50°C (-40°F to 122°F)
• Package environmental rating: IP65 for electronics
• Weight: 0.3 kg (0.7 lbs)
• Dimensions, W × L × H: 72 × 131 × 39 mm (2.8" × 5.2" × 1.5")
• EMC compliance: designed to the requirements of EN 12895:2000
• Net Weight: 0.3 kg

It is supposed that the controller 1220-2201 should be reprogrammed for each individual application. The 1220-2201 controller is fully programmable, via the CURTIS Model 1313-4331 Handheld Programmer or 1314 PC Programming Station. This means the controllers can be tailored to the needs of specific applications. In addition to configuration flexibility, use of the programmer offers diagnostic and test capability.
