Stepper Motor
When you double click on an Stepper object, a window like the one pictured will open.
- At the top of the window, information about your device and the properties of this particular channel will be listed.
- In the middle, the motor position and velocity is displayed in real-time. Press the "Engage" button to provide power to the motor. By default, motor position is measured in sixteenths of a step. If you want to measure position in a different unit, change the rescale factor (for example, a rescale factor of 1/16 would result in steps instead of sixteenth steps).
- At the bottom, motor properties can be specified:
- Acceleration: How fast the motor will try to reach the specified velocity limit. If the motor is stalling before reaching max speed, the acceleration may be too high. If the acceleration is too low, the motor may spend too much time in the stepper's mechanically resonant speed and stall.
- Velocity Limit: The maximum speed the motor will try to reach. Measured in sixteenth steps per second.
- Target Position: The position in sixteenth steps (or another unit if the rescale factor is specified) that the motor will move to.
- Current Limit: The maximum amount of current supplied to the motor's coils. See your motor's recommended coil current to determine optimal settings.
A second tab allows for continuous rotation instead of specifying a position.
