Electrical and performance details
- Chopper drive with MOSFET output stage; chopper frequency scales with supply voltage to reduce ripple losses and heating.
- Auto current reduction lowers holding current when idle to reduce heating and power consumption.
- Resonance compensation and mid‑band stability allow reliable full‑power operation across speeds; a “fill” circuit transitions current waveform from sinusoidal at low speed to square at high speed for maximum torque.
Mechanical, thermal, and protection notes
- Thermal design: low current consumption and efficient MOSFET outputs minimize drive heating; typical installations still require ventilation or heatsinking per the manual.
- Fault protection: built‑in fault detection (overcurrent/overtemperature) and protected outputs.
Controls, wiring, and compatibility
- Inputs: standard step/direction or pulse/direction logic (see manual for pinout and logic levels).
- Motor compatibility: designed for bipolar stepper motors commonly used in CNC, robotics, and automation; recommended for NEMA 23/34 frames.
