Cont. Signal name
A Manual arbitrary reverse run speed selection
[Function]
In speed control during manual arbitrary reverse run, this signal enables the program check speed constant.
[Operation]
When this signal is ON, the program check speed constant is used for speed control. When this signal is OFF, the
command speed in the normal machining program is used.
The feedrate for manual arbitrary reverse run is controlled by the "Manual arbitrary reverse run speed multiplier" (R379)
when operation is in jog mode. In handle mode, the feedrate is controlled by the ratio of the handle pulses per unit time
and "#19007 program check constant".
When this signal is OFF, the command speed in the normal machining program is used.
<The speed used when the "Manual arbitrary reverse run speed selection" (MORSP) is ON>
 When jog mode is selected:
Manual arbitrary reverse run speed is calculated from the following formula.
Manual arbitrary reverse run speed multiplier
Program check speed constant
 When handle mode is selected:
The manual arbitrary reverse run speed can be calculated from the following formula.
Change amount of handle pulse per unit time
× Manual arbitrary reverse run speed multiplier
Program check speed constant
 Rapid traverse override or cutting override can be exerted on the command speed in the machining program.
 Reverse motion is performed if the value of the manual arbitrary reverse run speed calculated with the above formula is
a negative value.
 As the same rate of change of the manual arbitrary reverse run speed is applied to all part systems, synchronization of
the part systems can be maintained.
However, synchronization is not guaranteed when synchronization relationship is broken due to rapid traverse override
or cutting override.
 If the value of the "Manual arbitrary reverse run speed multiplier" (R379) or the amount of change of handle pulses
exceeds "#19007 Prg check constant", the value is clamped at "#19007 Prg check constant".
The manual arbitrary reverse run speed never exceeds the command speed.
