1 — OVERVIEW
Like all Curtis PMC motor controllers, this family offers superior operator
control of the vehicle’s motor drive speed. Features include:
✓ Full bridge power MOSFET design, providing
• infinitely variable forward, reverse, drive, and brake control
• silent high frequency operation
• high efficiency
✓ Programmability through the 1307 handheld programmer
✓ Complete diagnostics through the 1307 programmer and Status LED
✓ Full compliance with all applicable international standards and TÜV re-
quirements
✓ Available for single-ended or wigwag 5kΩ potentiometer throttles and 0–5V
throttles (both standard full stroke and restricted range)
✓ MultiMode™ input selects between two different operating modes, thus
allowing optimization of vehicle characteristics for different driving condi-
tions (for example, indoor/outdoor)
✓ Speed limit input provides linear variable speed limiting with an external pot
✓ Improved linear acceleration and deceleration with softened response for
smooth operation
✓ Current limiting in both driving and regenerative braking modes; increased
regen braking current limit available for applications requiring enhanced
braking
✓ Load compensation stabilizes speed on ramps and over obstacles
✓ High pedal disable (HPD) function monitors status of the throttle during
turn on and prevents operation until the throttle has been returned to neutral
✓ Key off decel function provides a controlled deceleration if the keyswitch is
turned off while driving
✓ Comprehensive fault detect monitors main contactor, output stage, throttle
demand vs. output, etc., and disables the drive functions if any conditions are
outside specified limits
✓ ISO 7176 compliant throttle fault detection circuitry shuts off controller if
throttle pot signal goes out of range for any reason
✓ Optional missing brake detector forces neutral in the event of an open brake
circuit
✓ Anti-rollback/anti-roll-forward circuitry sets brake delay according to speed
and direction for improved braking response and minimized rollback on
hills, etc.
