Product Description

The 5430-230 is manufactured by Pacific Scientific. It is part of the 5000 Series Stepper motor drives.  It is designed to run cost-effective board-level drivers as well as intelligent motion systems. The 5430-230 offers reliability, top performance, and user-friendly software control. The 5430-230 drive is a highly efficient bipolar chopper that uses pulse width modulation to control the winding currents of the stepper motor automatically. The 500 Series drive delivers the right outputs to drive the two-phase stepping motors and accepts direction, step pulse, and the current control inputs.

The stepper motor drive supplies controlled phase current and delivers voltages of around 18 to 75 vdc. The drive has a NEMA 23 rating, and the power levels are shielded against overheating and phase to ground and phase-to-phase short circuits. An output logic signal and brightened LED indicates the presence of a short circuit. After detecting a fault, the short circuit detector automatically clears. The 5000 Series Stepper motor drive comes with an ICR (Idle Current Reduction). This feature enables the motor winding currents to be electronically minimized by 50% when the motor is at a standstill. You can enable or disable it through a circuit board jumper.

Pacific Scientific has provided one logic input to enable the operator to program levels of output current to the stepper motor. The 5430-230 has programmable current levels of 0 and rated. Because of excitation of cosine/sine current in the microstepping mode, the actual level of RMS current while microstepping is 70% rated current. The feature of the current boost is switch selectable. The 5430-230 has extra circuitry to eradicate midrange frequency unsteadiness. Midrange unsteadiness can be described as a region of potential unsteadiness that comes because of magnetic, electronic, and mechanical aspects of any stepper motor system.
