Cont. Signal name
A Manual arbitrary reverse run mode
[Function]
This signal enables manual arbitrary reverse run function.
The manual arbitrary reverse run is performed by controlling the feedrate during automatic operation in the memory or
MDI mode. The feedrate is controlled in proportion to the manual (jog) feed speed or manual rotation speed (handle).
[Operation]
The manual arbitrary reverse run is enabled while in memory or MDI mode and when this signal is ON. During the manual
arbitrary reverse run, the manual mode (handle or jog) must be turned ON at the same time as this signal turns ON, as the
axis is moved in the manual mode (handle or jog).
Speed control during manual arbitrary reverse run is also enabled if the "Manual arbitrary reverse run speed selection"
(MORSP) and the "Manual arbitrary reverse run speed multiplier" (R379) are commanded.
However, when the parameter "#1260 set32/bit0" (Switching to actual cutting mode during automatic operation) is set to
"1", switching ON/OFF of this signal in a specific operation block during thread cutting, thread cutting cycle and tapping
cycle does not switch ON/OFF of the "Manual arbitrary reverse run mode ON" (X715). For the specific movement block,
refer to the section of the "Actual cutting mode (thread, tap) in manual arbitrary reverse run" (Y761).
