Protects the motor and battery by capping the maximum amperage.
Indicates a self-test failure. Often requires a power cycle or indicates internal damage.
The controller uses a "Flash Code" system via a status LED or detailed text strings on a programmer to communicate errors. Common Diagnostic Codes: curtis 1520 controller manual
The throttle signal is outside the programmed range. Check for loose wires or a faulty potentiometer.
Designed to withstand harsh industrial environments, including moisture and dust. Protects the motor and battery by capping the
Dedicated pins for Forward, Reverse, Interlock, and Brake switches.
Always install a properly rated main fuse in the B+ line. The controller uses a "Flash Code" system via
Essential for speed and position feedback; usually requires a dual-channel (quadrature) encoder. ⚙️ Programming and Parameter Tuning
These are the three-phase outputs to the AC induction motor. Ensure these connections are tight and insulated. Low Power Control Wiring (35-Pin Connector)
Ensure the controller is mounted to a clean, flat metallic surface to facilitate heat dissipation.
