MCFB_Jog

 Function - Define to jog an axis in the selected direction at a defined speed.

• This function or function block can be used with PLCopen Motion engines.
• This function or function block is used to command motion in a designated direction at a defined rate.
  • This may be used where continuous motion is required (e.g., a conveyor system or in a setup mode for manually jogging the axis).
• The JogPlus and JogMinus inputs select the direction the motion occurs in.
  • Motion starts when the JogPlus or JogMinus input is TRUE.
    Motion stops when the input is FALSE.
  • Only one of these inputs should be enabled at a time.
  • If both are selected, the motion stops.
• If another motion is active when the jog is requested, that motion is aborted and the jog starts.
• The En input (FFLD editor only) must be high.
  • Typically wired to the rail.
