MotionWorks IEC61131-3 Toolboxes: 2013-09-13 474
Reverse_MC_Direction
This function block was designed for use with the Home_LS_Pulse function block in the PLCopen Toolbox. It
changes the enumerated type MC_Direction#positive_direction to MC_Direction#negative_direction or vice
versa so that the function can move the motor one direction into a limit switch with MC_StepRefLimit, and the
other direction when searching for the Index Pulse with MC_StepRefPulse.
