Stepper configuration#
Axis can produce up to 75000 steps per second (75KHz step rate). The maximum output RPM depends on the desired micro-stepping (Steps/Rev). For linear applications, the maximum output linear speed depends additionally on the Unit/Rev setting.
E.g. With 8x micro-stepping we configure for 1600 Steps/Rev and this yields a maximum output RPM of 2812.5.
Additionally, in linear mode and in metric units, assuming a 5mm ballscrew/leadscrew pitch (Unit/Rev is 5mm) results in 14062.5 mm/min maximum speed.
