Information About STP-DRV-80100
The STP-DRV-80100 is part of the SureStep series of enclosed DC stepper drives engineered for bipolar motor control. It utilizes a dual MOSFET H-bridge, 4-quadrant output stage with 4-state PWM current regulation at 20 kHz to optimize torque and efficiency. The drive supports multiple command interfaces including step and direction, CW/CCW, A/B quadrature, internal indexing through the communication port, and analog velocity control. Configuration and tuning are performed using SM-PRO software via the integrated RS-232 RJ11 port, allowing parameter adjustment and diagnostics for industrial environments.
Key Features:
- High Current Output: Provides up to 10A per phase for demanding stepper motor applications.
- Wide DC Input Range: Operates from 24 to 80 VDC for flexible system integration.
- Advanced Microstepping: Adjustable from 200 to 51,200 steps per revolution for precise positioning.
- Multiple Command Modes: Supports step and direction, CW/CCW, A/B quadrature, analog velocity, and internal indexing.
- RS-232 Communication Port: RJ11 interface supporting SCL and ASCII protocols up to 115.2k baud.
- Integrated Protection: Includes overvoltage, undervoltage, short circuit, and over-temperature safeguards.
- Performance Enhancements: Features anti-resonance damping, torque ripple smoothing, and command signal filtering.
- Idle Current Reduction: Automatically reduces motor current at standstill to minimize heat generation.
The STP-DRV-80100 delivers the reliability and precision required for industrial motion control, positioning systems, and automated machinery.
