Assigned to a particular function.
Command signal for stepper motors, indicates the commanded direction of
motion, either forward or reverse.
Electronic signal amplifier that converts motor control command signals
into higher-voltage signals suitable for driving motors.
A hardware device that provides signals or electrical current to activate a
transmission line.
A device that translates mechanical motion into electrical signals; used for
monitoring position or velocity in a closed-loop system.
The number of lines per unit of measure. Units can be inches, centimeters,
revolutions, and so on.
A type of signal conditioning that removes unwanted noise from the signal
being measured.
The coarsest mode of stepper motor driving that occurs when fully
energizing the windings.
A stepper motor mode. For a two phase motor, half-step mode is done by
alternately energizing two windings and then only one. In half step mode,
alternate steps are strong and weak but there is significant improvement in
low-speed smoothness over the full-step mode.
An input or output is high if the voltage is higher than the specified digital
logic high level.
