Wait-On/Off - Mitsubishi Electric MELSEC iQ-R16MTCPU Programming Manual

WAIT-ON/OFF

The WAIT-ON/OFF function starts/pauses the positioning for points that are set, depending on the bit device status.
For WAIT-ON/OFF operation, set the expansion point item setting (b6) to ON, and set the WAIT-ON/OFF setting and device
No. for each point of machine positioning. WAIT-ON/OFF is set in the machine positioning data. (Page 55 Machine
Positioning Data)
Operation example
When WAIT-ON and dwell time are set to the second positioning point, WAIT-OFF is set to the third positioning point, and M-
codes "10 to 30" are set to each positioning point.
"[St.2122] Machine WAIT (M43906+32m)" turns ON when each point is waiting for the conditions to be established.

• WAIT-ON/OFF controls the start and pause of positioning for the positioning points that have WAIT-ON/OFF
set to them. In the example above, WAIT-ON is set to positioning point 2, and the operation stops at the
position of the point block set in positioning point 1 when waiting for the conditions to be established.
• The WAIT-ON/OFF set to the first positioning point where machine program operation started is disabled.
When executing WAIT-ON/OFF at the first positioning point, set a transition program describing the wait
conditions with an Motion SFC program directly before the machine program operation.
• When the value for the establishment of WAIT-ON/OFF conditions is updated during the decelerating of the
positioning point directly before, the updated values are used for WAIT-ON/OFF conditions, or positioning to
the next positioning point starts.
• When dwell time is set to the positioning point directly before the positioning point with WAIT-ON/OFF set,
the establishment of conditions/waiting for the conditions to be established for WAIT-ON/OFF is enabled
after the dwell time of the positioning point directly before has elapsed.
• When M-code is set to the positioning point with WAIT-ON/OFF set, and waiting for the WAIT-ON/OFF
conditions to be established, the M-code does not change until the conditions are established.
