PERMANENT MAGNET
MOTOR SPEED CONTROLLER
MODEL 1212
Mobility System
FEATURES
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 under-voltage or over-
temperature.
• Optional speed limit potentiometer input provides direct and
linear control over the maximum vehicle speed.
• Proprietary algorithms help prevent gearbox wear while
providing smooth starts and reversals.
• The vehicle is brought to a complete halt before the
electromagnetic brake is applied, ensuring safe and secure
stopping under all conditions.
•
Charger inhibit input prevents driving while charger is connected.
• Emergency Stop Decel function ensures a smooth “brake to
stop” when the key is turned off or a fault occurs that requires
the vehicle to stop.
• Anti-roll back/roll-forward function provides smooth and safe
vehicle control on hills and ramps.
DESCRIPTION
The Curtis Model 1212 Motor Speed Controller provides precise
and smooth control of permanent magnet drive motors for battery
powered vehicles.
• Internal main contactor provides secure power-off.
• Boost current gives a brief boost of current greatly improving
performance with transient loads such as starting on a hill,
crossing thresholds, climbing obstacles, etc.
Easy Installation and Setup
• Industry standard footprint, mounting centers and wiring
allows drop-in replacement of other controllers.
• The Model 1212 is easily programmed with Model 1311
handheld or 1314 PC programmers, or can be supplied
pre-programmed.
•
Accepts all standard throttle types, including single-ended and
center-off (wig-wag and unipolar).
• Simplified troubleshooting and diagnostics.
• Standard Mini-Fit Molex Jr. and Faston terminals provide proven,
robust wiring connections.
APPLICATION
Optimized for use on modern 3 or 4 wheel mobility aid scooters.
However, the model 1212’s programmable options also allow it to
be used on any low power permanent magnet motor application.

Valuable Additional Features
• Optional Push-Switch input releases the brake and allows the
motor to free-wheel.
• Push-too-Fast feature restricts vehicle speed even with the key
off or with batteries disconnected.
• Automatically compensates 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 modes).
• Power Saver function prevents the controller draining the
battery when vehicle is inactive.
• Battery Discharge Indicator output.
• Optional Speed Inhibit input offers flexibility to reduce speed
or prevent drive, e.g. when seat is lifted.
•
Adjustable brake hold voltage reduces heating of the brake coil.
• Reverse Beeper function alerts bystanders.
• Electronics sealed to IPX5.
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.
• System start-up checks detect a defective throttle, brake, or
associated wiring and disables drive.
