VXM® Calculation of Steps, Direction and Speed Lead Screw Code for Velmex Linear Products BiSlide® (with standard 1.8º (200 step) motor) Speed for the VXM 1000 SPS (steps / sec)* Lead Screw Pitch > Gear Ratio Velmex Rotary Tables *Calculated with a VXM half step control and a 1.8° (200 step) motor

VXM® Calculation of Steps, Direction and Speed Lead Screw Code for Velmex Linear Products BiSlide® (with .9º (400 step) motor) Speed for the VXM 1000 SPS (steps / sec)** Lead Screw Pitch > Gear Ratio Velmex Rotary Tables **Calculated with a VXM half step control and a .9° (400 step) motor

VXM® Calculation of Steps, Direction and Speed - Direction is relative to the device the motor is on. On screw drive actuators like UniSlides®, BiSlides® and XSlides™, positive is the direction moving away from the motor. - On worm gear type Rotary Tables like the Velmex B4800 or B5990, positive is normally counter clockwise (CCW.) To convert from “real” units to steps when using a 1.8°, divide the distanced desired to move by the Advance Per Step. (Distance / Advance per Step = Steps for the VXM) Example #1: To move 3 inches with the BiSlide E04 lead screw (3 ÷ 0.001 = 3,000) requires a 3,000...

Linear Distance with Stepper Motors and Velmex Lead Screws (per minute) Velmex Lead Screw Code BiSlide® Step Motor Rate: in half Steps/Sec.

Linear Distance with Stepper Motors and Velmex Lead Screws (per second) Velmex Lead Screw Code BiSlide® Step Motor Rate: in half Steps/Sec. · Calculated with VXM™ Motor Controller which operates at 400 half-steps per revolution · Standard motor resolution is 1.8º per full step or 0.9º per half-step with the VXM

Shortest Advance with VXM and 1.8° (200 step) Step Motor The increment of a single half-step* is BiSlide® XSlide™ UniSlide® Lead Screw Pitch > · Calculated with VXM™ Motor Controller which operates at 400 half-steps per revolution · Standard motor resolution is 1.8º per full step or 0.9º per half-step with the VXM *System step resolution or smallest repeatable move is dependent on system orientation, rigidity, friction, wear and applied load. † Velmex also offers Vexta High Resolution 0.9° motors. When driven by the VXM, resolution is 800 steps/rev. This effectively doubles the resolution but...
