Performance reference
Thrust-speed curves
The reference test used a DS-OLS8-FPD bipolar constant-current chopper microstep drive. Recommended load limit: 231 kg. Actual performance depends on lead, drive settings, acceleration, screw support and duty cycle.
Application-ready integration
Configure the complete linear-motion assembly
Lead choice establishes the basic balance between speed, resolution and force. Reliable machine performance also depends on winding selection, drive current, acceleration, external guidance, screw support and operating duty.
