Curtis 1520 Controller Manual ^hot^ -

F1 and F2 connect to the motor field windings. Reversing these will change the default forward/reverse direction.

A casual glance at the wiring diagram shows battery positive → contactor → B+ terminal, B- to controller ground, and M- to motor armature. But the manual’s fine print hints at the half-bridge topology. The 1520 is typically a (though some versions support permanent magnet or separately excited). The manual’s discussion of "current sensing," "flyback diode protection," and "field weakening" (if present) quietly reveals the limits of the hardware: a maximum duty cycle of 100%? No—the manual will warn against 100% PWM for extended periods due to ripple current. The deep reader realizes the manual is a constraint map : every specification (e.g., 36V or 48V nominal, 200A peak) hides a thermal budget and a semiconductor junction temperature limit. curtis 1520 controller manual
