Jog
Temporary command that runs the motor at a dedicated low speed for setup or positioning.
The Explain card
- Plain English
- Jog runs the motor at a fixed, usually slow, preset speed for as long as the jog input is held. Release it and the motor stops.
- Example
- A technician threads a web through a machine by tapping jog to inch the rolls forward. The machine moves a little each time and stops the moment the button is released.
- Why it matters
- Jog is for setup, threading and positioning by hand, and it bypasses the normal reference and the normal ramps. Because it is a maintained command with no seal in, it is also the safer way to move a machine while someone is near it.
- Hook
- Inch it forward, let go, it stops.
