1220C-2201 24V 40A Original 1220 EPS Electric Power Steering Controller for Brushed PM Motor

1220C-2201 24V 40A Original 1220 EPS Electric Power Steering Controller for Brushed PM Motor

Overview:
The 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 original AC traction controllers for Curtis 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.

Features:
Advanced Motor Control
· Absolute position control mode.
· 16 kHz PWM switching frequency ensures silent operation.
· Advanced PWM techniques produce low motor harmonics, low torque ripple, and minimized heating losses, resulting in high efficiency.
· Configurable homing methods, center offset, and end-stop protection.
· 24V, 40A 2-minute current rating.
· 24V nominal supply voltage.

Maximum Safety
· Dual steering command inputs and dual analog position inputs for redundant check.
· Fault output can be used to turn off traction controller's main contactor or interlock connection.
· Steered wheel position (angle) output can be used to limit the traction motor speed.
· Following error check ensures the wheel position tracks the steering command.
· Power On Self-Test: FLASH, ALU, EEPROM, software watchdog, RAM, etc.
· Power On Hardware Check: Motor Open, Motor Short, and MOSFET short.
· Periodic Self-Tests: EEPROM parameters, Motor Open, and command and feedback devices.

Unmatched Flexibility
· Integrated hour-meter and diagnostic log functions.
· 840 Spyglass for Curtis can be connected to show traction and steering information such as BDI, hour meter, fault, traction speed, and steered wheel angle.
· +5V low-power supply for input sensors, etc.
· Original 1313 handheld programmer and 1314 PC Programming Station provide easy programming and powerful system diagnostic and monitoring capabilities.
· External Status LED driver gives instant diagnostic indication.

Robust Reliability
· Intelligent thermal cutback and over-voltage/under-voltage protection functions maintain steering while reducing traction speed until severe over/under limits are reached.
· Standard Mini-Fit Jr. for Molex and Faston terminals provide proven, robust wiring connections.
· Electronics sealed to IP65.
· Reverse polarity protection on battery connections.
· Inputs protected against shorts to B+ and B-.
