The PST5042 Stepper Drive is a versatile, fully digitalstepping drive based on a DSP (Digital Signal Processor) with advanced control algorithms.
Electrical Specifications:
· Output Current: Ranges from 0.5A to 4.2A (3.0RMS).
· Supply Voltage: +20V to +50V DC.
· Logic Signal Current: 6mA to 16mA.
· Pulse Input Frequency: Up to 200kHz.
· Isolation Resistance: 500M.
Function Description:
· Micro step Resolution: Programmable with 16 selectable micro step resolutions, allowing up to 25,600 steps/rev. Set using DIP switches.
· Current Setting: Operating current can be configured via DIP switches, supporting currents up to 4.2A.
· Automatic Standstill Current Reduction: After the last pulse, the current automatically reduces to 50% of the selected operating current within 0.4 seconds.
Control Signals: PUL+ and PUL-: Pulse command signal, DIR+ and DIR-: Direction control signal, ENA+ and ENA-: Enable/disable control signal.
· Motor Connector: A+, A-, B+, B- for motor connections (reversing wire connections changes default motion direction).
· Power Connector: Recommended power supply output of +24V to 48VDC.
· Indicators: LED indicators for power (Green) and fault status (Red). Reset the drive by re-powering it after resolving issues.
Applications:
· The PST5042 drive is suitable for a wide range of stepping motors, from NEMA 14 to NEMA 24.
· It finds use in various machines, including medical devices, laser cutters, laser markers, high-precision X-Y tables, and labelling machines.
