Like all Curtis motor controllers, the 1230 offers superior operator control of
motor speed. Features include:
✓ 60–200 amp AC induction motor controller
✓ MultiMode™ feature allows two distinct user-selectable operation
modes
✓ Programmability through the Curtis 1311 handheld programmer and
1314 PC programming station
✓ Complete diagnostics through the 1311 and 1314 programmers and
through the controller's built-in Status LED
✓ Throttle input for single-ended or wigwag 5kΩ pots or 0–5V throttles
(both standard full stroke and restricted range)
✓ Active precharge of controller capacitor bank extends life of main
contactor tips
✓ Two hourmeters—total KSI-on hours and drive hours—and their associ-
ated maintenance timers are built into the controller, with EEPROM
storage (no battery)
✓ BDI calculations performed within controller
✓ Meets EEC fault detection requirements
✓ Fault detection circuitry on throttle inputs can be used to inhibit
operation if throttle signal goes out of range for any reason (applies both
to the traction throttle and, in applications that include a proportional
valve, to the hydraulic throttle as well)
✓ Stall protection
✓ Internal reverse polarity protection (no external diode required)
✓ Continuous diagnostics during operation, with microprocessor
power-on self-test
✓ All output drivers are short-circuit protected and provide built-in
coil spike protection
✓ Positive battery connections for all inputs
✓ Fully protected inputs
✓ Internal and external watchdog circuits ensure proper software operation
✓ High environmental protection rating (IP53)
✓ 3-wire serial interface for multifunction display
