Function Block MCFB_JogPLCopen motion icon

Description

This function block is defined to jog an axis in the selected direction at a defined speed. The En input (FFLD editor only) must be high. Typically wired to the rail.

The AxisID selects the axis to jog. The JogPlus and JogMinus inputs select the direction the motion will occur in. Only one of these inputs should be enabled at a given time. If both are selected the motion will stop. If other motion is active when the jog is requested that motion will be aborted and the jog will start.
